The accelerated growth of cities has led to the reduction of green areas and a disconnection from nature.This situation negatively affects well-being, causing stress, anxiety, and health problems stemming from a life surrounded by asphalt and concrete. To counteract these effects, a trend is emerging that transforms the perception of the urban environment: urban gardens, small green oases where people can grow their own food, maintain a connection with nature, and contribute to the sustainability of the planet.
What is an urban garden?
Un urban garden It is a space located within a city – on balconies, terraces, patios, rooftops or community spaces – where vegetables, fruits, aromatic herbs and flowers are grownThis type of cultivation doesn't require large areas of land: it can be grown in containers, growing tables, or small plots, adapting to both private and public spaces, or those shared by the community.
Urban gardens They are not a recent invention. They historically emerged in periods of scarcity to supplement food, and are currently used for both fresh food production to promote social welfare, environmental education and improving urban biodiversity. In addition, they have become popular in schools, neighborhood associations, and even hospitals, demonstrating their versatility and positive impact in all areas.
What benefits do urban gardens provide?
- Health and nutrition: They provide organic foods without chemicals, allowing you to enjoy fresher, healthier, and tastier products. Homegrown crops reduce the use of polluting plastics and packaging.
- Mental and physical well-being: Gardening acts as a natural therapy alleviating stress, improving mood, and promoting physical activity through planting, watering, and harvesting.
- Education and social cohesion: They are an educational tool for children and adults, allowing them to learn about the plant cycle, sustainability, and healthy habits. In the case of community gardens, they reinforce collaboration between neighbors and create intergenerational bonds.
- Ecological impact: They actively contribute to improving air quality, reducing the carbon footprint, and promoting urban biodiversity. Plants capture CO2, filter pollutants and moderate ambient temperature.
- Reducing food wasteHarvesting only what you need significantly reduces waste generation by adjusting consumption to actual demand.
- Landscape restoration: They transform degraded lots into quality green spaces, preventing their use as improvised landfills and revitalizing neighborhoods.
Direct contact with nature It provides important positive effects, especially in urban environments where screens and technology abound. Simply watching plants grow, collaborating with others, or eating food nurtured from seed strengthens self-esteem and ecological connection.
Types of urban gardens
- Home gardensSmall spaces in private homes, such as terraces, large windows, or balconies. They allow for family consumption of vegetables, herbs, and fruits.
- School gardens: It is usually located in schools or institutes, promoting the environmental education and student participation.
- Community gardens: Plots or land shared by several families, neighbors, or associations, where farming is done collaboratively and community activities are encouraged.
- Municipal gardens: Spaces managed by local councils, open for public use under specific regulations.
- Guerrilla gardens: Informal crops in unused public spaces, promoting urban revitalization without the need for large investments.
- Therapeutic orchards: Added in hospitals or health centers, where the crop is used as a therapy to improve quality of life and physical and mental rehabilitation.
- Hydroponic and vertical systems: Recent technologies that allow for the use of very small spaces and the consumption of less water, using nutrient solutions and vertical structures.
What to plant in an urban garden?
The success of the urban garden is linked to the appropriate choice of species according to space, climate and lightSome of the most recommended plants for urban cultivation are:
- Short-cycle vegetablesLettuce, radishes, spinach, or carrots. They're easy to grow, require little substrate, and allow for continuous harvests.
- VegetablesTomatoes, cucumbers, eggplants, peppers. These plants can grow in deep pots and require plenty of sun exposure.
- Aromatic herbsBasil, parsley, mint, thyme, chives, and rosemary. Ideal for small pots and very useful in the kitchen.
- Small fruitsStrawberries, raspberries, blueberries. Some varieties are suitable for pots or planters.
- comestible flowersMarigolds, pansies, nasturtiums. They beautify the garden and attract pollinators.
To maximize space, it is recommended to practice compatible crop associations and the use of techniques such as rotation to promote soil fertility.
How to create an urban garden step by step
- Choose the location.: Find a sunny location, protected from strong winds and with good ventilation.
- Select containers and growing tables: You can opt for planters, pots, raised growing tables or modular systems such as Minigarden, which allow for a better use of vertical space and water saving.
- Prepare the substrateUse nutrient-rich organic substrate. Mix compost, coconut fiber, and worm castings for greater water retention and aeration. Avoid nutrient-poor soil if you want vigorous plants.
- Fertilize ecologically: Use organic fertilizers, homemade compost or worm castings to enrich the soil, especially during transplanting.
- Efficient irrigationWater deeply, avoiding waterlogging, and adjust the amount according to the season and the needs of each species. Watering during the coolest hours reduces evaporation and water stress.
- Planting and careMaintain the recommended distances between plants to avoid overcrowding. Prune lightly, remove weeds, and monitor for pests and diseases.
- Pollinator attraction: Add flowers, install insect hotels, or use aromatic plants, which are essential for ensuring pollination and biodiversity.
Tackling pests ecologically
Prevent and treat pests It is essential in the urban garden. The use of repellent plants such as basil or marigold, crop rotation and association, and biological control systems, promoting the presence of predators like ladybugs. Natural preparations such as garlic or neem oil are effective and safe for the environment.
Additional recommendations for a thriving urban garden
- Choose suitable containersClassic pots for narrow corridors, trays for leafy crops, growing tables for added convenience, and planters for combining species.
- Take advantage of every seasonThere are ideal crops for every season. Some vegetables, such as carrots and lettuce, can be planted almost year-round under protected conditions.
- Acquire knowledgeParticipate in workshops, courses, or local urban garden networks, where you can share resources, tips, and seeds.
There are also numerous initiatives at the local level to bring urban agriculture to the entire population, in schools, neighborhoods, and municipalities. Neighborhood networks, associations, workshops, and school projects are increasing the presence and impact of urban gardens as a driver of ecological and social change in cities every day.
Everyone can benefit from an urban garden, adapting it to their available space and time. Whether at home, at school, in a community, or for therapeutic purposes, gardening in the city is possible, rewarding, and transformative for both those involved and the urban environment as a whole.
