Choosing Your Farming Space & Crops

Choosing the right crops for your urban farm is essential for making the most of your available space. This section will guide you through selecting crops that thrive in your environment and offer high yields, while also helping you optimize your space for maximum productivity.

Commonly Used Spaces

Rooftop Farming

Rooftops are an excellent choice for urban farms, particularly in densely populated cities where ground space is limited. These elevated spaces can support container gardening, raised beds, and small greenhouses, allowing you to grow fresh produce without requiring traditional farmland.

When considering rooftop farming, it's essential to assess the structural integrity of the roof to ensure it can bear the load of soil, water, and plants. Additionally, take into account sunlight exposure and wind patterns, as rooftops are often more exposed to the elements.

Vacant Lots

Urban areas often have unused or underutilized lots that can be converted into productive farms. These spaces are ideal for growing a wide variety of crops, especially if the soil quality is suitable.

Before starting, it's crucial to conduct soil tests to check for contaminants like lead or other pollutants, which are common in urban environments. If the soil isn't safe, raised beds or container gardening can be a viable alternative.

Working with local governments or private owners to gain access to these lots can also help secure affordable land for your urban farming project.

Indoor & Vertical Farming

Indoor farming offers year-round growing opportunities, especially when paired with technologies like hydroponics or aquaponics.

By utilizing artificial lighting and climate control, you can cultivate crops in unconventional spaces such as warehouses, basements, or even unused office spaces.

Vertical farming, in particular, allows you to maximize the use of limited square footage by growing plants in stacked layers. This method is highly efficient in terms of water and space, making it ideal for urban farmers looking to scale production in a small footprint.

Considerations for Farming Space

Sun

Sunlight and Water Access

Ensure your chosen space receives adequate sunlight for the crops you intend to grow. Rooftops and outdoor lots generally have good exposure, but indoor farms will need to rely on artificial lighting systems. Water access is also crucial. If you're farming outdoors, ensure that your water source is reliable and close by.

Ground

Soil Quality and Safety

For outdoor spaces, soil quality is a significant factor. Urban soils can be contaminated by industrial activity or previous land use, so testing for heavy metals and other pollutants is vital. If the soil is unsuitable, consider using raised beds or containers with clean, imported soil to avoid potential health risks.

Field

Space Layout and Design

Efficiently using your space is essential to maximize productivity. In rooftop and vacant lot setups, plan for pathways, irrigation systems, and composting areas. In vertical and indoor farming, ensure that your layout allows for proper airflow, access to plants for maintenance, and efficient use of lighting and water resources.

Choosing Your Crops

When choosing crops for your urban farm, it’s essential to consider factors like space limitations, local climate, and community demand. By selecting crops that are well-suited to your environment and goals, you can maximize your yield and ensure the success of your farm, whether you're growing for personal use or market sales.

Factors to Consider When Choosing Crops:

  • Space Constraints: Crops like leafy greens, herbs, and small vegetables (lettuce, spinach, basil) are ideal for small or vertical spaces.
  • Growing Conditions: Consider crops that thrive in urban climates. If space is indoors, look into crops that grow well in controlled environments, like microgreens or hydroponic plants.
  • Market Demand: If the farm is commercial, assess local demand (from restaurants, markets, or community members). Highlight how understanding your market can drive your choice of crops.
  • Ease of Maintenance: For beginners, suggest crops that are relatively easy to grow and maintain, such as radishes, peppers, tomatoes, or herbs like mint and basil.
  • Leafy Greens

    Leafy greens are an excellent choice for urban farms because they grow well in small containers, making them perfect for limited spaces like rooftops, balconies, or even vertical gardens. Spinach, kale, and arugula are fast-growing crops that can be harvested multiple times throughout the growing season, providing a continuous supply of fresh greens.

    These plants thrive in cooler temperatures, so they’re well-suited for early spring and fall planting. Additionally, they have shallow root systems, which means they don’t require deep soil, making them ideal for raised beds and other space-conserving setups. Plus, leafy greens are a popular staple in many diets, ensuring there’s always a market for them in urban settings.

    Herbs

    Herbs like basil, parsley, and cilantro are a high-demand option for urban farmers because they offer great returns even in limited space. These herbs grow well in containers, window boxes, and small garden plots, making them ideal for urban environments.

    With minimal water and maintenance needs, herbs are relatively easy to grow, making them perfect for beginners. Basil is a favorite for home cooks, while parsley and cilantro are key ingredients in many cuisines, meaning there’s always demand from local restaurants and markets. Urban farmers can also stagger their planting to provide a steady supply of fresh herbs throughout the year, boosting both the farm’s productivity and potential profit.

    Fruit-Bearing Vegetables

    Tomatoes and peppers are two of the most popular fruit-bearing vegetables for urban farms, offering high yields even in compact spaces. With proper support systems like trellises or stakes, tomatoes can grow vertically, maximizing the use of limited space.

    Peppers, both hot and sweet varieties, thrive in small garden beds or large containers, making them versatile for any urban farming setup. These vegetables are also relatively hardy and can adapt to various growing conditions, including container gardens and greenhouses.

    Because tomatoes and peppers are commonly used in a wide range of recipes and cuisines, they have a consistent demand in local markets and households, making them a profitable option for urban farmers.

    Climate & Seasonality

    Understanding your local climate is essential for selecting the right crops for your urban farm. The USDA Plant Hardiness Zone Map helps you determine which plants will thrive in your region by showing the average annual minimum winter temperature for different areas. This tool is a valuable resource for ensuring your crop choices are well-suited to your environment, leading to healthier plants and better yields!

    You can also reach out to your local Extension Office to learn more about which crops will thrive in your area.
