Abstract

:
Urban horticulture represents a sustainable way of dealing with the challenges of modern cities, including urbanization processes, population growth tendencies, a lack of green areas, environmental pollution and food insecurity. This study aimed to (1) investigate the perceptions of citizens of Novi Sad municipality, Republic of Serbia, toward urban horticulture and (2) assess plant materials appropriate for cultivation in urban gardens and suggest urban spaces completely designed with the use of various forms of edible fruit species, including roses. The same questionnaire was administered with a four-year time gap, in 2019 and again in 2023, before and after the coronavirus pandemic. To investigate plant materials suitable for urban gardening, relevant articles in Google Scholar, Scopus and Web of Science platforms were searched. The questionnaires’ results showed significant differences between the two years concerning respondents’ attitudes toward urban horticulture’s impact on food safety, socialization and personal health and development, which could have been influenced by the pandemic. Vegetables were grown by most respondents, commonly in household yards and gardens. The main motivations for participating in community urban gardens were to grow food for their own consumption and to make charitable contributions, followed by the motivation ‘to socialize and relax’. Exemplary designs of an urban pocket, kindergarten yard and atrium courtyard are presented, providing insights into numerous possibilities for landscaping with fruits.

1. Introduction

Food security has been seen as the fulfillment of the entire population’s needs at all times regarding physical and economic access to sufficient, safe and nutritious food that will enable them to live active and healthy lives [1]. It is conditioned by the food system’s success, comprising a wide range of activities from production to consumption, whose individual aspects, paradoxically, pose serious environmental threats [2]. The current trend of population growth has led to an estimate that, by 2030, about 60% of the world population will live in urban areas [3]. Urban agriculture could substantially influence global food production through the exploration of new locations for cultivation, with at least 100 million people actively engaged in this form of gardening worldwide [4]. Concomitantly with advocating a more sustainable approach to food production, urban horticultural activities are being performed in a number of urban spaces, including private home gardens, public community gardens, allotment gardens, gardens within schools and universities and rooftop gardens, as well as small spaces such as balconies and spaces that occupy larger areas, such as urban farms [5].
Although practiced since cities’ emergence, the production of food in some contemporary dense and high-rise-filled urban areas is not always residents’ first-choice activity [6]. Throughout history, every rapid and large-scale initiative that resulted in an increase in city dwellers’ engagement in the maintenance of urban gardens has been related to the increased need for fresh food in times of crisis, including poor living standards in periods during and after wars, financial crises and, most recently, the pandemic waves in 2020 and 2021 [7]. In countries with low living standards, urban agriculture is generally practiced in order to provide nutritionally adequate and safe food while at the same time generating self-employment opportunities, direct revenues or savings, which contribute to greater social stability [8]. Even when food security is not endangered, the reasons for urban gardening are numerous. Urban horticulture is associated with a number of benefits to individuals, society and the environment. According to Lovell [9], urban horticulture provides a wide range of functions, thus contributing to food production, energy conservation, waste management, biodiversity conservation, microclimate control, the greening of urban areas, economic improvement, community socialization, residents’ health and well-being, cultural heritage and education. Many studies have shown that food is certainly not the only and, for many participants, not the main motivation to become involved in agricultural activities in urban conditions. The multifunctionality of urban gardens was confirmed by Pourias et al. [10]. They found that the motivation of gardeners to participate in urban collective gardens, in addition to the amount of produced food and its quality, is closely linked to opportunities to socialize with others, to improve their physical and mental health, to expand their knowledge and skills, to enjoy their leisure time, to make contact with nature and escape city life, and to make an impact on the urban landscape. Freeman et al. [11] found that people also valued their private gardens because of the process of ‘creating’ the space over time, as an expression of ownership and identity, and that gardens were seen as a means for learning to care about life and respecting nature. In a study conducted by Chalmin-Pui et al. [12], the results indicated that most people engaged in home gardening for pleasure and joy, while Church et al. [13] found that regardless of the motivations for growing their own food, gardening practitioners were happier than those who were not engaged in this activity. According to Goldstein et al. [14], the practice of producing food in urban areas significantly affects environmental impacts on urban food demand, concurrently influencing environmental issues such as runoff attenuation, urban heat island mitigation and carbon sequestration, while Scheromm [15] concluded that the existence of collective gardens and the residents who take care of them bring the agricultural and urban worlds together, contributing to the achievement of many sustainability goals [16].
Developed, industrialized countries are experiencing an increasing interest in urban horticulture, resulting in increases in the number of locations for food-growing purposes, their diversity and the number of participants enrolling in waiting lists to join a garden—as in Paris, Montreal and New York [10]. Although urban gardening practices and possibilities for food growing in urban conditions in countries of Southeast Europe have been studied in recent years [17,18,19,20,21,22,23,24,25,26,27], research on urban horticultural practices and spaces suitable for this form of food production in the Republic of Serbia is still limited. Djokić et al. [28] studied the character and history of urban gardens and gardening practices in Belgrade, the capital of Serbia, questioning the further development of the investigated urban spaces from aspects of regulation, legislation and design improvement. There is no adequate legislation in Serbia that would recognize urban gardening as a type of green area use, although some initial steps toward the regulation of collective urban gardens have been made [29]. Čepić et al. [29] studied the motivations of citizens to participate in urban gardening in three municipalities of Belgrade. Their results showed the high interest of respondents in this form of activity, but individual plots were preferred over shared gardens. Access to healthy and fresh food, followed by recreation and light physical activity, proved to be the most important motivation to garden. During the assessment of urban pockets in Novi Sad, the second-largest city in Serbia, Narandžić and Ljubojević [30] identified spaces suitable for urban gardening purposes. To the authors’ knowledge, similar studies in Novi Sad, except for studies on urban soil quality in terms of edible plant cultivation [31,32] and plant materials suitable for urban gardens [33], have not been conducted. Despite the presence of different informal spaces of unknown ownership and wild gardens in the urban environment of Novi Sad, where the growing of edible plants by city residents was observed, in addition to food production in private household gardens and spaces between buildings, research is lacking on the areas that they occupy; their number, ownership and locations; gardeners’ characteristics; and the types of plants grown. Also, there are no studies on citizens’ perceptions of urban horticulture, nor their willingness to produce food for their own needs or to participate in collective gardens.
This study aimed to investigate what the citizens of Novi Sad municipality consider to be the benefits of urban gardening, from the aspects of its relation to the environment, food security and the economy, socialization and society, human well-being and opportunities to learn and play, and to evaluate their familiarity with, participation in and motivation for urban gardening. The pilot study was conducted in 2019 and 2023 to observe whether their attitudes had changed over time due to the occurrence of the COVID-19 pandemic.
The second part of the study aimed to show how edible species—fruits, including roses—could be incorporated into the urban space by suggesting three different types of urban gardens. The plant materials suitable for edible landscaping purposes have been investigated.

2. Materials and Methods

The questionnaire was administered with a four-year time gap, in 2019 and 2023, in order to observe changes in the public’s awareness of urban horticulture over time—their familiarity with the term and potential benefits of activities included in this form of food production, their involvement in food production, the choice of edible plants and spaces for growing purposes, their willingness to expand their knowledge on that topic and their motivation to eventually participate in urban gardening at the community level. As a study area, the City of Novi Sad was selected (longitude 19°50′ E, latitude 45°19′ N), the capital of the Autonomous Province of Vojvodina and the second-largest city in the Republic of Serbia. The municipality of Novi Sad occupies an area of 699 km2 with its 16 settlements [34,35]. According to the Statistical Office of the Republic of Serbia [36], the population estimate in the City of Novi Sad in 2021 was 363,789, with a constant increasing trend. Urban community gardens are not present in the city area, and research on private urban gardens and allotment gardens has not been conducted to the authors’ knowledge. Therefore, there are no data on citizens’ involvement in urban gardening, although spaces suitable for this type of activity were investigated by Narandžić and Ljubojević [30].
An online questionnaire was adopted to collect data, as it is one of the most straightforward methods that allows participants to freely reply, is less expensive and, in a short period of time, can be made available to a large number of people [37]. The first survey was conducted between 10 April and 10 June 2019, while the second was carried out between 7 February and 7 April 2023. The questionnaire was formed and distributed on social networks using the Google Forms platform via a link and emails sent by members of the research group. The link was accessible by computers and mobile phone devices. Also, to expand the sample of respondents, hard copies of the same questionnaire were distributed during different sessions held in the City of Novi Sad, enabling part of the population who do not have access to the internet to participate in the survey. All respondents were volunteers who had been previously informed that their answers would be used for research purposes only, thus protecting respondents’ confidentiality. Participants who gave incomplete responses or skipped answering particular questions were excluded from the research during data cleaning (eight respondents in 2019 and five respondents in 2023). After data cleaning, the final number of respondents in 2019 was 333, while in 2023, 217 respondents were included in the study, making a total of 550 participants.
The questionnaire’s form was structured and consisted of 14 questions: 9 close-ended multiple-choice questions, 4 multiple-answer multiple-choice questions with an additional ‘other’ answer option and comment field, and 1 question comprising 21 statements with a four-point Likert scale for each statement (1—disagree; 2—not sure; 3—partly agree; 4—agree). The questions were grouped into five segments: five questions were asked to gather information on demographic characteristics (gender, age, occupation, education, place of residence); two questions were asked to find out respondents’ familiarity with the term urban horticulture and how they found out about it; 21 statements within one question aimed to provide insight into personal attitudes toward food production, gardening activities and urban gardens; three questions were about growing food in urban conditions, the plants that are grown and the spaces in which production occur; and three questions were asked to investigate respondents’ interest in learning about opportunities that urban horticulture offers and their willingness to participate in workshops on that topic and in the maintenance of an urban garden in the immediate vicinity of their place of residence, without monetary compensation. Statements were divided into five sets, which were related to the impact of activities encompassed by urban horticulture/gardening. These included four statements regarding the impact on the environment, four statements related to the impact on food safety and the economy, four statements regarding the impact on social relations and society, five statements related to the impact on personal health and development, and four statements with regard to the impact on learning and play activities. With regard to places in which food-provisioning activities are performed, answers included both household yards and gardens. To avoid misunderstandings arising from the different terminology used for similar spaces in different cultures, definitions for both terms in the context of this study are given. The term ‘yard’ is considered an area immediately adjacent to the house that, depending on its position in relation to the entrance to the household area, could be seen as the front yard, side yard or backyard; it is often partially surfaced, with or without an area where plants are grown. On the other hand, the term ‘garden’ represents an area within the yard or within walking distance from the family home, mainly with open soil, where different plants are cultivated, mostly edibles. For the full questionnaire, see Appendix A, Table A1.
Data analysis was completed in MATLAB software, version 7.8 (R2009a). This also included sample reduction, which allowed us to draw conclusions about part of the population with certain characteristics and test whether those characteristics affect opinions about various questions concerning urban horticulture. A non-parametric Chi-square homogeneity test and Mann–Whitney test were performed to test the distributions of two independent samples at levels of significance of α = 0.01 and α = 0.05. Also, a correspondence analysis was performed to explore the relationship between categories with regard to responses to multiple-choice questions.
When assessing plant materials suitable for urban horticulture by searching for relevant articles in Google Scholar, Scopus and Web of Science platforms, different search strings for crop characteristics were used, including the following keywords: ‘fruit’ (different species), ‘cultivar’, ‘low vigor’, ‘compact’, ‘columnar’, ‘dwarf’, ‘disease’, ‘pest’, ‘resistant’, ‘tolerant’ etc. The investigation was oriented toward temperate fruit species, including pome, stone, berry and nut fruits. The search was conducted exclusively in English.
The proposed designs of three urban spaces—urban pocket, kindergarten yard and atrium courtyard—were established on the basis of several principles. Plant materials were planned to provide a diversity of species, plant sizes and growth forms, textures, colors and scents, forming an attractive space that engages all senses. The cultivars were chosen with the aim of enabling fruit harvesting throughout the season. The vegetation was used as a buffer from urban environmental threats, as a protective layer from insolation and as a visual and physical barrier within the space. The plants were planned to be planted directly in the soil or in different forms of containers, enabling the utilization of species with specific growth requirements. In order to protect children and enable a safe and healthy space within the kindergarten yard, thornless cultivars were chosen. Where applicable, cultivars resistant or tolerant to the main diseases and pests were proposed, while rootstocks were chosen to attain the size-controlling effect on scions. The proposed urban gardens were designed according to principles of design such as balance, rhythm, repetition, emphasis, proportion, contrast and harmony in order to attain both the optimal functionality and high esthetic value of the space.

3. Results and Discussion

3.1. Investigation of Citizens’ Familiarity with Food Production in Urban Conditions and Its Benefits—Survey Results

For surveys conducted in 2019 and 2023, the sample populations consisted of 87.69% and 69.12% women, respectively (Table 1). A higher rate of questionnaires filled out by women in comparison to the number of male respondents was also obtained by other authors [13,38], indicating the possibility that women are more open to participating in surveys. However, this by no means indicates that women are more involved in urban food production. The demographics with regard to the age, occupation and education of respondents are shown in Table 1.
Concerning age, the lowest number of participants were older than 65 years and retired in both years, which is presumably related to the inability of the older generation to access the questionnaire online, not to less engagement in urban horticulture by respondents within this age category. Our assumption is in line with the findings of Čepić et al. [29], who found that older citizens in Belgrade (Serbia) seemed more willing to engage in collective urban gardening, considering that they have more free time and possess the necessary skills to garden. The highest number of respondents in both years belonged to the age category between 25 and 40 years (56.46% in 2019 and 59.91% in 2023), followed by respondents from 41 to 65 years old (26.42% in 2019 and 28.57% in 2023). In terms of occupation, respondents were predominantly employed, with a share of 67.87% in 2019 and 78.34% in 2023 in relation to the total sample population. The highest number of respondents had finished bachelor studies, followed by high school graduates and respondents with a master’s degree. The sample distribution with regard to the place of residence was consistent in both years of the questionnaire’s administration, with around 80% of participants living in the city and the remaining respondents living in rural settlements.
The survey showed that in relation to the total number of respondents, 66.06% in 2019 (220 respondents) and 71.43% in 2023 (155 respondents) were familiar with the term ‘urban horticulture’ in its modern perception, referring to the growing of plants in an urban environment with the aim of producing food. In both years, more than 50% of individuals in the sample population familiar with the term were females. In 2019 and 2023, 73.68% and 65.21% of respondents younger than 25 years, respectively, were familiar with the investigated activity. Of the total number of 25–40-year-old respondents, 61.17% in the first year and 66.92% in the second year were familiar with the term. The results obtained for the third age group, where 71.59% in 2019 and 82.25% in 2023 positively answered the asked question, indicated that survey participants 41–65 years old were to the greatest extent aware of urban horticulture in 2023, followed by the first age group in 2019. With regard to occupation and education, the highest share of respondents familiar with urban agriculture in 2019 was recorded among the ‘pupil/student’, ‘high school’ and ‘bachelor studies’ categories, while in 2023, ‘employed’, ‘high school’ and ‘master studies’ categories dominated (values above 70% in relation to the number of residents in that occupation/education category). It is interesting that in 2019, 76.56% of respondents from rural settlements were familiar with urban horticulture, while urban residents reached a share of 63.57% in relation to the total number of respondents in this category. In 2023, the situation had changed slightly, with 70.73% of respondents from rural and 72.59% of respondents from urban settlements being aware of the term. Dunnett and Qasim [39] found that younger adults were less involved in gardening than adults older than 35 years. This is, to some extent, in line with our results, showing that respondents from 41 to 65 years old were more familiar with the term urban horticulture than those aged 25 to 40 years (significant difference at the level of significance α = 0.05). Similar findings were obtained by Church et al. [13], who found a significant increase in food growing with the increase in respondents’ age, where the largest number of respondents who grew their food were older than 65 years. However, the same authors did not find a strong influence of the respondent’s gender and education on engagement in this form of activity. Our results corroborate these findings regarding the influence of gender and education on the respondent’s familiarity with urban horticulture.
For each structural category (gender, age, occupation, etc.), tests were performed to determine whether there was a significant difference between subcategories with respect to respondents’ familiarity with the term urban horticulture. In order to test these differences, the Mann–Whitney test for large samples (α = 0.05) was performed. The tests were conducted in pairs for each pair of subcategories having a large enough sample size, and in the cases where there were significant differences, one-sided tests were performed in order to test whether respondents in a certain category were more familiar with urban horticulture than those in the other one. Subcategories with only a few sampled respondents were excluded from the analysis since small sample sizes cannot give reliable test results. The conducted Mann–Whitney test showed that the only significant difference within categories was between the two age groups, as stated above. In the same manner, the Mann–Whitney test was conducted to test whether respondents in a certain category tended to express a greater desire to learn about urban horticulture than those in the other one. At the level of significance α = 0.05, it was confirmed that there were no significant differences within the gender, age, occupation and education categories. However, the place of residence did significantly influence respondents’ willingness to expand their knowledge, where survey participants living in urban settlements expressed a greater desire to learn about urban horticulture. As presented in Table 2, more than 60% of respondents in both 2019 and 2023 (61.56% and 66.82%, respectively) who wanted to learn more about the opportunities that urban horticulture provides belonged to the ‘urban’ category regarding the place of residence.
The largest number of respondents familiar with urban horticulture found out about this form of activity on the internet—about 42% in both surveys (Figure 1). In 2019, 12.61% of survey participants had learned about urban horticulture from social sources—family members, neighbors or friends—as well as from television or radio shows. The second survey’s results showed an increase in the number of respondents who became familiar with the term through social interaction (23.50%) and via television/radio (15.67%). The source of information for the lowest number of respondents was printed publications, while under ‘other’, the respondents indicated that they had found out about urban horticulture during their education. These findings are partially in accordance with the study conducted by Pollard et al. [40], in which online sources, family and friends were highly rated responses, while, in contrast to our results, almost 80% learned about food gardening from books. Contingency tables with the corresponding residuals show that responses varied with regard to population age, occupation and education, as well as regarding the year of investigation (see Supplement, Tables S1–S3). In 2019, respondents in the youngest part of the population (<25 years old) were more likely to find out about the term from family members, neighbors or friends, while respondents who were 41 to 65 years old were more likely to be informed via the internet. Interestingly, in the year after the pandemic, adults from the category 41–65 years old were mostly informed through social interactions and from newspapers/journals. The respondents within the 25–40-year-old category were more likely to be unfamiliar with the term than other categories of respondents in both years. Most employed respondents found out about urban horticulture via the internet in both years and were also less likely to be informed about it via social contacts. Regarding education, social interaction was most likely the source of information within the ‘high school’ category, while respondents with a faculty degree were more likely to find out about urban horticulture via internet sources in both 2019 and 2023.
City residents’ answers to the question ‘Do you or someone in your immediate environment engage in food production to meet your own needs, in urban conditions?’ are presented in Table 3. All retired respondents answered positively to this question in both years, although their number was insufficient to make an assumption. The results show that the highest number of residents who live in the city and who personally grow or whose family members grow plants for their own consumption, with regard to occupation, belonged to the ‘pupil/student’ and ‘unemployed’ categories. In terms of education, the groups of respondents who finished high school and had a bachelor’s degree gave the most affirmative answers in 2019, while in the second survey, the highest share within the category was recorded for ‘doctoral studies’ and ‘high school’ categories (disregarding only one respondent within the first group). Such results do not indicate a strong connection between education and food-producing activities, corroborating the findings of Church et al. [13], but rather point to other factors determining respondents’ involvement in urban horticulture, such as experience in agricultural practices or having the time and space to grow edibles [41]. A limitation of this question is that we do not know exactly who in the household was involved in food production, since the question referred to the respondents themselves but also to their family members. Because of this, it was not valid to perform tests that could provide answers to questions like ‘Whether the unemployed are more inclined to grow their own food than the employed respondents?’ or ‘Whether the respondents with lower education are more inclined to engage in food production for their own needs than respondents with higher education?’.
The respondents’ perceptions toward the benefits of urban horticulture in terms of the mean level of agreement showed differences between both the individual statements and the impact categories (Table 4). The highest level of agreement for an individual statement in 2019 (average value 3.78) was recorded for statements 4, regarding the impact of urban gardens’ establishment on the revival and beautification of the urban environment, and 19, regarding the influence of gardening on the individual’s connection with nature. In 2023, statement 19 was rated with the highest level of agreement (3.87). In both years, the average scores for statements within the ‘Impact on learning and play activities’ and ‘Impact on environment’ groups were the highest—3.63 and 3.60 in 2019 and 3.67 and 3.65 in 2023, respectively. The statements’ average score for the ‘Impact on social relations and society’ was the lowest, with values of 3.25 in 2019 and 3.32 in 2023. The lowest rating in both 2019 and 2023 was given to statement 9—‘Gardening encourages socialization with other people’—with means of 2.83 and 3.02, respectively. Such low scores indicate that the main form of urban gardening present in the investigated area is individual gardening in the privacy of people’s own households due to the absence of allotment gardens in Novi Sad. For all other statements, the average level of agreement was ‘partly agree’ to ‘agree’. These results indicate that, although almost completely based on food production in households’ gardens, urban horticulture was highly valued among survey participants in both 2019 and 2023. This is no surprise, bearing in mind that food production in a more traditional context in Serbia, regarding mainly agricultural activities in households located in non-urban settlements, represents a valuable source of food that contributes greatly to food supplies throughout the year, enabling both fresh and stored products’ consumption. For example, the overall vegetable production in yards and gardens in Serbia constitutes about 20% of open-field production [42]. The phenomenon of growing food in urban environments has thrived under different circumstances within different societies, where the history of allotment gardens dates back more than a hundred years [43]. In order to better understand the tendencies of the urban population in Novi Sad to engage in food-provisioning activities, further research should focus on changes affecting population demographics and urbanization processes that may increase residents’ desire to return to nature through urban horticulture [33]. In order to test the hypothesis that the opinions of the population about the statements did not change over the four years, the Mann–Whitney and Chi-square homogeneity tests were used. Based on the two independent samples from the years 2019 and 2023, the aim of the two-sided Mann–Whitney test for large samples was to test the hypothesis that the distributions of the corresponding populations do not differ at the level of significance α = 0.05. In other words, the ‘significant’ (abbreviation ‘Sign.’ used in Table 4) results show that the attitude of the population with respect to the chosen statement was not the same in the two years. In order to test the same hypothesis using the Chi-square test, the 2019 and 2023 populations were divided into four categories depending on their attitudes toward the corresponding statement, and the test was performed for levels of significance α = 0.01 and α = 0.05.
The performed tests indicated a change in general attitudes toward urban horticulture’s impact on food safety, socialization and personal health and development, as well as on the improvement of gardening skills, over the four years. The most significant differences were found between the respondents’ opinions with regard to the impact of urban horticulture on issues regarding food provisioning and the health and development of individuals engaged in such activities. Those results were reflected in the highest mean differences per category. In 2023, respondents were more convinced that the food production for their own needs affects food sustainability and provides access to a wider range of healthy, nutritious food. This could be related to the experience of growing their own food at a time when they were working from home and the inability to participate in a large number of activities outside the household, as well as the reduced food supply in markets due to transportation problems, as also noticed by Chari et al. [44]. Similarly, Bhattarai and Adhikari [6] stated that since the coronavirus pandemic, people who lived in urban settlements have begun to realize that the delivery of food from distant areas is not always reliable, which indisputably affects the provision of different food products. The results are in line with the findings of Lindsay et al. [45], who found that the COVID outbreak had changed people’s consumption practices and engagement in different activities not practiced before, such as bread baking, food growing and bicycle riding. The same authors concluded that the public’s response to the pandemic demonstrated that consuming less was possible and that household food production could be enjoyable. Although rated with the lowest score in both years, the influence of gardening on socialization was more appreciated in 2023, presumably indicating the growing need to connect with others after home isolation during the pandemic and the recognized benefits of social interaction for human well-being [46]. Gross and Lane [47] found that the social dimension was an integral part of the engagement in urban gardening, especially for those at a younger age and adults reminiscing about their childhood. This included opportunities to use the garden as a space for social games and sports activities, enabling siblings’ relationships to flourish, but also as a place to remember and commemorate past relationships and people. Regarding the positive impact on personal health and development, more respondents in 2023 valued gardening as an opportunity for recreational purposes and relaxation [48], as well as an activity that encourages personal development [49], strengthens self-confidence [50] and positively affects the emotional status of an individual [51] and a child’s development [52].
In order to test the hypothesis that the place of residence does not affect one’s opinion about statements on urban horticulture, the Mann–Whitney test for large samples was performed. The results confirmed the hypothesis, which showed that at the level of significance α = 0.05, rural and urban residents had similar opinions on the investigated matter. The means for individual statements were also calculated to determine the difference between the means of populations living in rural and urban settlements (Table 5). The highest difference between means was found for the statements regarding the employment opportunities that urban horticulture provides, the influence of gardening on children’s development and its educational function.
Compared to the respondents from the city, respondents from rural settlements agreed to a greater extent with the statement, ‘The establishment of urban gardens increases the chances of employment for the urban population’. This could reflect the overall opinion of the rural population that agricultural activity such as urban horticulture could provide employment, since food production is one of the main job opportunities in rural areas [53]. The greater connection of rural residents to food production was also found by Ančić et al. [19], who recorded that food self-provisioning was more frequently practiced in rural areas and smaller settlements than in urban environments. Almost 80% of respondents who lived in the city agreed that ‘Gardening has a positive effect on a child’s development’, about 10% more compared to rural residents. This could indicate the accentuated need of urban residents to provide safe and healthy spaces for their children, being aware of the negative consequences of growing up without a yard or a garden and a devastating lack of green spaces in the immediate vicinity of their homes, but also of the importance of open spaces during the restricted usage of indoor spaces [54,55,56]. According to Miller [52], children who participate in gardening activities communicate their knowledge of the world to others and convey and learn how to manage their emotions while developing valuable skills—self-confidence, initiative, science skills, etc. In a study conducted by Dunnett and Qasim [39], a fifth of respondents perceived gardens as an important aspect of creating a safe environment for children because of their protective enclosure, which mitigates urban threats. The higher agreement of urban residents with the educational character of gardening in comparison to rural residents could be presumably due to urban residents’ understanding of food production as a great opportunity to learn how to grow and maintain plants with the possibility of tasting their own products [10,57], rather than perceiving it as a work opportunity and the main source of the household’s food supply in the case of some rural residents. Scheromm [15] agrees that, even if urban horticulture does not provide a realistic alternative for food production that completely meets the needs of residents, urban gardens do provide a valuable opportunity for environmental and agricultural education.
In both years of investigation, more than half of the survey’s participants, although familiar with urban horticulture, were eager to learn something more about food production in cities (Table 6). About half of the participants who declared that they were not familiar with the subject of the research in 2019 wanted to acquire new knowledge, while that share in 2023 was higher. In general, people in 2023 were more interested in learning, but not in participating in workshops on that topic, with only 35.94% of respondents interested in such events. The lack of interest in participating in events related to urban horticulture promotion could be influenced by the reduced willingness to stay in crowded places due to the previously experienced risk of contagion during the pandemic [58].
The plants mostly grown in the urban environment were different vegetable crops—as answered by 44.74% and 47.93% of respondents in 2019 and 2023, respectively (Figure 2). The responses ‘fruits’ and ‘herbs’ were marked by around 30% of respondents, while ‘other’ responses included different flowering species (edible) and ornamentals, with one respondent particularly worried about safety issues regarding the production of food in the polluted urban environment. The cultivation of plants for the family’s own consumption most often took place in the household yard, which was selected by 34.23% and 38.25% of survey participants in 2019 and 2023, respectively (Figure 3). A private garden was marked by around 30% of respondents, while balconies were least but not negligibly used for food production. Under the category ‘other’, orchards, raised wooden garden beds in the spaces between multihouse buildings and apartment buildings’ hallways were recorded, as well as the growing of plants in pots in apartments and on window sills. Similar to responses about the plant type, some respondents marked more than one answer regarding the spaces in which the plants were grown. While investigating urban gardens in Paris and Montreal, Pourias et al. [10] found that vegetables and small fruits, aromatic herbs and flowers (including edible flower species) were mostly grown, while in larger gardens, pome and stone fruits and nuts were found. The diversity of plants in the garden was also valued, although some gardeners produced only one crop or range of crops, which is in accordance with our findings. Cruz-Cárdenas and Oleas [59] found that private urban gardens in their study mostly comprised ornamentals, followed by food and medicinal plants, while fruit trees were grown by about half of the investigated gardeners. Djokić et al. [28] found that in gardens located in urban areas, the cultivated plants were vegetables, herbs and flowers. The restricted growing of fruiting trees and bushes is indisputably related to the small dimensions of spaces, where ornamental species and recreational purposes become priorities [39], but it could also be related to the higher level of maintenance associated with fruit growing or having less knowledge of the cultivation practices needed for successful fruit production.
When asked about their motivations to join urban gardens in the immediate vicinity of their homes without monetary compensation, some respondents marked more than one reason for participation, showing their strong willingness to engage in this sort of activity (Figure 4). With regard to the motives to participate, the highest number of responses in 2019 (32.13% of respondents) was recorded for the reason ‘I would participate if the produced food is intended for humanitarian purposes’, which reflects the social value of community gardens. In 2023, the largest number of respondents (36.41%) marked the answer regarding the food-provisioning urban horticulture dimension—‘I would participate if it were possible for me to use produced food’—which was possibly influenced by the previously discussed pandemic-related issues. After possibilities to consume produced food, to make a charitable contribution and to socialize and relax (recreational dimension of community gardens), for some respondents, it was appealing to participate if all materials needed for gardening were provided (less than 20% of participants in both years). Less than 5% of respondents were not attracted to join a community garden in both years, while 28.53% in 2019 and 22.58% in 2023 said that they did not have time to engage in such activities. The responses regarding the motivations to engage in food production in urban gardens per respondent category are shown in Supplement, Tables S4–S6. The respondents from the second age group (25–40 years old) were most likely motivated by the possibility of using the produced food in both years, while for 41–65-year-old respondents, the main motivations to participate in urban gardens were ‘to donate food’ and ‘to socialize and relax’. In 2019, respondents younger than 25 years were most likely to participate if all of the resources needed for production were provided, while after the pandemic, they were more likely to consider urban gardens as places for socialization and relaxation. The employed respondents were more likely to be motivated to join urban gardens ‘to socialize and relax’ rather than for other reasons in both years, but in 2023, they were more likely to respond that they did not have time for such activities. Regarding the unemployed, the respondents in 2019 were mostly motivated by the possibilities of using and donating the produced food, while after the pandemic, they were more likely to participate in urban gardens if all resources for production were provided. As expected, a lack of time as a reason to not engage in urban horticulture was mostly marked by employed respondents. The motivation ‘to socialize and relax’ was most likely to be valued by respondents with higher education (master’s and doctoral degrees) in both years, while respondents within separate education categories were differently motivated by the possibilities of using and donating the produced food before and after the pandemic. Pollard et al. [40] found that motivations for home and community gardeners differ slightly, where production-, enjoyment- and health-related motives were the most significant for home gardeners, while social interaction was among the first three motives for community gardeners. According to Church et al. [13], an increase in ‘growing your own food’ in European countries was largely associated with poorer households and possibly economic hardship, with geographical aspects involved. The economic dimension of food production for one’s own needs was also recognized in a study by Wakefield et al. [60], where participants referred to improved food access and the cost-saving aspect of such practices. In their research on the food function of urban gardens, Pourias et al. [10] found that more than half of gardeners produced enough food to cover 50 to 100% of the needs for some fresh products during the season, greatly contributing to the household’s food supply. In a survey conducted by Partalidou and Anthopoulou [61], ‘the need to grow my own food’ was the most important motive for gardening, which was associated with the physical need for fresh, healthy products. While investigating the motivations of small-scale gardeners, Turner [62] found that food safety and access to clean and safe vegetables that do not pose health risks were priority motives for gardening, rather than simply availability and access to large quantities of food. The ‘sharing and giving’ of produced food to others, primarily to adult children who do not live with their parents in the same household anymore and members of the extended family, followed by friends and colleagues, was observed as a strong motivation for gardening by Pourias et al. [10]. The gardeners who produce the largest quantities of food are not necessarily those who share the food to the largest extent, according to Pourias et al. [63]. Pollard et al. [40] found that 95% of participants in their survey shared, gifted or donated food, but only 36% of them purposefully grew extra food to share it with others. On their list of food recipients, giving the food to charities was in fifth place. Vitiello et al. [64] recorded that almost all of their community garden participants reported sharing their produce with those in need, while in their study of communal and private urban gardens, da Cunha et al. [65] noted that products from almost half of the gardens were donated.
In order to prevent limitations that could arise from the selected form of the question, an option to add an opinion or motivation that was not listed by the authors was added to the questionnaire. However, no additional significant motivations were listed by survey participants, despite the wide range of motivations observed by other authors [12,57,66,67].

3.2. Urban Spaces’ Designs with Fruit Species and Roses as Edible Alternatives to Inedible Ornamentals

Urban horticulture is integrated into the urban economic and ecological systems, where urban residents represent producers, directly affecting the urban environment and urban food system [68]. As a result of intensive urban population growth, interest in the development of innovative technologies and sustainable urban farming practices is constantly increasing [69]. Ju et al. [70] argued that for uncontrolled, ground-based outdoor food production in urban conditions, the main goals encompass ecosystem service provision and environmental damage reduction, rather than the achievement of higher productivity, while Ramaiah and Avtar [71] agreed that growing plants in cities, in spaces free from concrete pavement, could significantly mitigate the negative consequences of climate change. From the perspective of a gardener, food could be grown in both conventional and unconventional ways, including variations between, where the first offers the possibility of growing almost any desired plant at the cost of unlimited resource exploitation—thus harming the environment—while the latter is based on the sustainable, thoughtful usage of plants and resource conservation [66,72]. Gardeners often choose varieties for their organoleptic characteristics, which provide them with tasty, fresh products, but they also value the opportunity to provide food with a known origin, without unnecessary chemicals applied during the process of production [10]. As our results and other studies discussed have shown, fruit species in urban gardening were present to a significantly smaller extent than vegetables, while opportunities for growing edible flower species in urban horticulture were recognized by only a few respondents.
Specific rootstocks’ and cultivars’ breeding objectives differ between separate groups of fruit species. However, the main fruit-breeding trends concern the simplification of orchard practices, the resistance or tolerance to negative biotic and abiotic influences, the expansion of production zones, the diversification of fruit traits, the achievement of greater health benefits and the consistently high quality of fruits—all with regard to the preservation of the environment [73]. Due to the numerous environmental issues related to fruit growing, including pesticide usage, uncontrolled water use and quality, biodiversity degradation, high energy consumption and the pollution of soil and air, integrated and organic approaches to fruit production emerged as sustainable methods for fruit production [74]. In terms of the growth habit of fruit plants for the purposes of urban horticulture, a gardener often chooses a plant to fit the garden, rather than for the improvement of production efficiency, which is the case in commercial production [75]. Various growth habits can be utilized even in small-sized urban gardens, including dwarf, compact, semi-dwarf, columnar, weeping and upright habits, as well as the combination of different growth habits in one plant—dwarf × compact, columnar × compact, dwarf × columnar, and many more [76]. The vigorous growth of many cultivars does not represent an obstacle to their utilization, even in smaller spaces, due to the easily attainable size-controlling effect of adequate rootstocks’ selection, which also improves the productivity and fruit quality of scions and adaptability to different pedo-climatic conditions and uncertain climate-change-induced meteorological events [77,78,79,80]. In this way, some old varieties can be preserved and used in urban conditions [81], while autochthonous germplasm can be utilized due to its valuable traits through its introduction to breeding programs with the purpose of enabling sustainable urban gardening [82,83]. The wide range of diseases and pests can severely impact food production, especially in home gardens where growers are not willing to use any chemicals that could harm the environment. On the contrary, some gardeners use inadequate doses of plant protection preparations, without thinking of possible soil contamination. Fruit breeding for resistance aims to provide cultivars resistant or tolerant to different diseases and pests occurring in fruits when plants are attacked by numerous causal agents—viruses and viroids, phytoplasmas, bacteria, fungi, etc. [84]. With the thoughtful selection of cultivars for the urban garden’s design, individual and community fruit gardens will thrive in any condition, providing gardeners with a high number of tasteful, non-chemically treated fruits throughout the season.
The lack of space in the urban environment, which limits the usage of vigorous plants, the perennial character of which postpones the harvesting of first fruits from the garden and, in most cases, necessary pesticide usage in fruit production, indisputably affects growers’ decisions regarding the choice of plant material [33,85]. Research on vigor, habit, productivity and adaptability to site conditions, as well as resistance to biotic stressors, leads to the selection of the most suitable and attractive rootstocks/cultivars for cultivation in numerous urban environments [86]. The investigation of the literature focused on plant materials suitable for growing in urban gardens, as explained in the Materials and Methods section, has provided insight into the wide range of cultivars characterized by low-to-moderate vigor, compact and/or columnar growth habits, resistance and/or tolerance to the main fruit diseases and pests, unfavorable growing conditions, etc.—traits of importance in urban horticulture. Some cultivars considered suitable for cultivation in urban gardens among pome and stone fruits are the apple cultivars ‘Goldlane’ [87], ‘Monnlight’, ‘Smaragd’ [88], ‘Lilac’, ‘Magenta’ [89] and ‘Colonade’ [90]; the pear cultivars ‘Ivanino zlato’ [91], ‘Armida’, ‘Manon’ and ‘Uta’ [92]; the peach cultivars ‘Bolero’, ‘UF ONE’ [87] and ‘GulfAtlas’ [92]; the almond cultivars ‘Kester’ [93], ‘Carina’ and ‘Rhea’ [94]; the plum cultivars ‘Dwarf’ [95] and ‘Jojo’ [96]; the apricot cultivars ‘Apridwarf’ and ‘Aprimed’ [93]; and the sweet and sour cherry cultivars ‘Chelan’, ‘Ebony Pearl’ [97] and ‘Morina’ [98]. Berry fruits also offer a wide range of cultivars characterized by desired traits, including the raspberry cultivars ‘Valentina’ [99], ‘Glen Doll’ [100], ‘Autumn Treasure’ [101] and ‘Cascade Harvest’ [102]; the blackberry cultivars ‘Fruloche’ [87], ‘Sweetie pie’ [94] and ‘DrisBlackEighteen’ [89]; the blueberry cultivars ‘Augusta’ [87], ‘Cosmopolitan’ and ‘Lielogu’ [102]; the currant cultivars ‘Ben Chaska’ [102], ‘Stikine’ and ‘Tiben’ [89]; the gooseberry cultivar ‘Hinsel’ [87]; and the strawberry cultivars ‘Grandarosa’, ‘Linosa’, ‘Merced’ [93] and ‘Florida Brilliance’ [94]. Among nuts, some cultivars are considered adequate to grow in urban gardens, such as the Persian walnut cultivar ‘Sexton’ [100], the hazelnut cultivars ‘Sacajawea’ [100], ‘Dorris’ [92] and ‘Somerset’ [89], and the chestnut cultivar ‘Jianding Youli’ [89]. For more details and species, see Appendix B, Table A2.
Besides the traditional fruit species, the genus Rosa sp. includes around 150–300 botanical species and thousands of hybrids and cultivars [103] that have the potential to be used in everyday nutrition. The ornamental value of roses has been recognized since the dawn of civilization, and today, they are used as cut flowers and garden or indoor pot plants [104]. Rose fruits are widely known as a valuable source of polyphenols and vitamin C, which exhibit various medicinal properties [105]. Although rose flowers have been used since ancient times as food ingredients and medical products, roses were mainly appreciated and recognized for their scent, aesthetic and decorative value. However, the edible aspect of rose cultivars is becoming more popular, because consumers are eager to try new flavors and to utilize the bioactive compounds in edible flowers [106]. People are changing their eating habits with the aim of achieving a healthier lifestyle, which has resulted in edible rose cultivars emerging as pioneers in both the food and nutraceutical industries due to the recognition of their valuable traits [107,108]. The growing of edible roses has been the object of various studies. Inter alia, De Morais et al. [109] evaluated the influence of different farming systems on the bioactive compounds, microbial diversity, aroma and color of edible red mini-roses (Rosa chinensis Jacq.); Butcaru and Stănică [110] investigated edible roses’ organic production, while the vegetative growth and production of three climbing edible roses (‘Crown Princess Margareta’, ‘Falstaff’ and ‘Brother Cadfael’) were assessed from the aspect of organic cultivation by Butcaru et al. [111]. In order to cultivate resistant and healthy garden roses that do not require chemical protection, the breeding of garden roses, next to fragrance, has been oriented toward disease resistance and extreme-condition tolerance [33]. Friedman et al. [112] investigated the yield, susceptibility to Botrytis cinerea and levels of antioxidants of 12 edible garden rose cultivars, concluding that the cultivars ‘English Sachet’, ‘Eterna’, ‘San Francisco’ and ‘Maxim’ exhibited the lowest sensitivity to disease. Rose material investigated by Božanić Tanjga et al. [113] included seven garden rose cultivars from the ‘Mella’ series, bred by the private breeding company ‘Pheno Geno Roses’. The results indicated the high potential of varieties from the ‘Mella’ collection for growing in urban conditions due to their attraction of a significant number of pollinators and their tolerance to the main disease-causing agents. In a study conducted by the same research group, Ljubojević et al. [33] further investigated those varieties, as well as varieties from eight other collections, in terms of disease resistance and added and aesthetic values. Prospective collection candidates that showed traits of importance for urban horticulture, including edible character and disease resistance to powdery mildew and/or black spot, included ‘Ruby Mella’ from the ‘Mella’ collection; ‘Dolce’, ‘Nadia Zerouali’ and ‘Jordi Roca’ from the ‘Edible’ collection; ‘Aromatic Aurora’, ‘White Aurora’, ‘Berry Bush Aurora’ and ‘Purple Aurora’ from the ‘Aurora’ collection (they are drought- and heat-resistant, have roots that can tolerate poor, heavy and saline soils and provide a plenitude of bright-orange edible hips); ‘Mina Frayla’, ‘Jelena Frayla’ and ‘Isidora Frayla’ from the ‘Frayla’ collection (most fragrant type); ‘Blush pixie’ from the ‘Pixie’ collection (patio roses, suitable for container cultivation) and ‘Blush Winterjewel’ from the ‘Winterjewel’ collection (hardy to low winter temperatures, very healthy and reliable).
The possibilities for fruit species’ utilization in the planning of different types of urban gardens have been explored through the design of three spaces—private, educational and public.
The urban garden shown in Figure 5 is a closed-type atrium courtyard, bordered on three sides by the walls of the house and on one side by a wall that separates the gardens of two neighboring houses. The paved areas at both exits from the house are connected by a path, which, like the planned vegetation, follows a circular pattern. The paved area positioned on the southwest side represents an area for the relaxation and gathering of household members, next to which are symbolically planted family apple trees, with varieties with different fruit colors and ripening times. In the southeastern corner of the garden, next to the paved area, it is planned to plant fruit species with a lower habit—currants and raspberries—thus leaving the sight from the window to the garden area clear, while the dynamics of the composition was achieved by alternating bushy raspberries and highly grafted currants. To attain an unobstructed view from the inside of the house from the northeastern side of the garden, an Asian pear, Nanking cherry and juniper with a horizontal–prostrate habit in planters and Buddha’s hand in a pot are planned. In the central part of the yard, flowering Japanese quince bushes are planned, combined with plumcot and cherry trees. Next to the wall in the garden’s northwest, disease-resistant edible roses, as well as a variety chosen for its high pollinator attraction ability, are recommended. Considering the small dimensions and closed character of the space, a properly raised lawn represents an important design component, providing a balanced composition. The element of water was introduced into the space in the form of water mirrors, which do not require much maintenance and increase the garden’s attractiveness. Since this kind of garden is a valuable family space, the proposed design offers opportunities for numerous playing, learning and gardening activities.
The design of the kindergarten’s fruit garden is presented in Figure 6. The garden is protected from the negative impacts of the high-traffic street on the southeast, as well as the medium-traffic street on the southwest, by the vertical layer formed with the use of sour and sweet cherry trees. On the northwest side, the garden is enclosed by a residential building, which is vertically greened with a kiwi vine. The garden is dominated by species and cultivars that do not require the use of chemical treatments, while for educational purposes, all types of fruit species are planned in the garden—pome, stone, berry and nut species, as well as citruses. Focus is placed on the variety of forms and colors throughout the growing season. The edible and sustainable context further encompasses the planting of local landrace of plum, chokeberry and corkscrew hazel shrubs, forming the middle layer of vegetation. A subtropical species—kumquat, for which children could care even during the winter months, when it is planned to be moved indoors—complements the seating space. Both kiwi and kumquat are ready to use, without peeling the skin, immediately after picking, which allows the children to enjoy a wide range of tastes right in the garden. The lowest vegetation layer consists of wild yellow strawberries, dwarf apple and apricot trees, blueberries and cranberries in high-raised planting beds. High-grafted black currant is also present in the design as a potted plant that adorns the northeast corner of the garden.
The edible design of an urban pocket in Novi Sad is shown in Figure 7. The concept aims to transform an uninviting, neglected space located in a busy transit area into a quiet urban garden for leisure time and an escape from the urban hustle.
A dogwood hedge encloses the garden from the street side, with an entrance framed with columnar apple cultivars extending over the trellis. An appealing entrance in the dense green hedge invites passers-by to stop and spend some time in the garden, further discovering other interesting species and forms. The space inside the garden is divided into two areas, with the use of the high-grafted European ground cherry trees and the jostaberry bush forming a visual barrier in the central part of the garden, enabling a more private stay for several people at the same time, despite the small dimensions of the garden. Dwarf and decorative forms dominate in the garden space, primarily due to a lack of space for the growing of more vigorous plants. Additionally, plant materials are selected in order to demonstrate that fruit species offer numerous possibilities for horizontal and vertical greening. Thus, wild strawberries are planned as ground cover instead of a lawn, while the next vegetation layer consists of dwarf forms of cherry, peach and apricot, complemented with sand cherry. Disease-resistant edible roses, with soft-peach-colored and gentle-pink petals, are planned to be located in the northern part of the garden. Along the wall of the residential building at the northwest garden edge, very decorative forms of cultivation are planned—Omega espalier and LePage of resistant apple varieties. The overall design is complemented by the soothing sound of water from the fountain in the central part of the garden.

4. Conclusions

Urban horticulture indisputably provides numerous benefits to both humans and the environment. The activities it encompasses offer valuable opportunities for citizens to contribute to the creation of sustainable and resilient settlements through food production practices strongly associated with human well-being on a myriad of levels. To investigate urban gardening preferences in Novi Sad, the second-largest city in Serbia, online and printed questionnaires were distributed in 2019 and 2023.
This study has shown that in the area of Novi Sad (Serbia), 69.35% of the respondents in 2019 and 67.63% in 2023 produced their own food (directly or by family members). The assessment of respondents’ attitudes toward urban horticulture showed that the levels of agreement with statements on urban horticulture’s impact on food safety, socialization and personal health and development were significantly different between the two surveys conducted in 2019 and 2023. Such results presumably indicate the impact of the coronavirus outbreak on respondents’ perceptions due to the many consequences of isolation and the inability to engage in one’s favorite activities, both individually and with others. Between the attitudes of respondents from rural settlements and citizens, the most significant differences were found to concern the employment opportunities provided by urban horticulture in cities, the influence of gardening on children’s development and the educational character of gardening—all of which could be related to the different opportunities provided by these two types of living environments and the main reasons for engagement in food production in those environments. Low scores (around 3 on a 4-point scale) for the influence of urban gardening on socialization indicate that the main form of urban gardening present in the investigated area is individual gardening in the privacy of people’s own households due to the absence of allotment gardens in Novi Sad. Nevertheless, survey participants were interested in engaging in community gardens mostly due to the possibility of consuming the produced food and donating the food to those in need. Fruit species were grown by less than 35% of respondents or their family members, while edible flowers were mentioned by only a few respondents. This accentuates the need to inform urban residents about the possibilities of fruit growing (including roses, often seen as non-standard fruit for ornamental purposes) in their gardens and yards and on balconies and roofs, as well as in different indoor spaces, through the three urban garden designs proposed in this article (private, educational and public). Fruit and rose breeding for the purposes of urban horticulture has resulted in a large number of cultivars suitable for urban gardens, enabling edible landscaping as a component of sustainable living. Future research should focus on the investigation of the number and character of gardens in the urban area, individual gardeners’ motivations to grow their own food, and the number, quality and safety of foods produced in urban households of Novi Sad.
