How to start a community garden

What the research shows

Shared ground has a way of turning neighbors into a community. The evidence for health benefits is real but modest. In a randomized trial in Denver and Aurora, Colorado, published in The Lancet Planetary Health in 2023, adults given a community garden plot ate somewhat more fiber, were somewhat more physically active, and saw larger drops in stress and anxiety than those on the waitlist. The authors note the fiber and activity gains came with wide uncertainty.

That's a fair way to think about it: a community garden isn't a cure, but it's a good place to be, with real people and real food.

Start with a group

A garden that depends on one person rarely lasts. Alabama Cooperative Extension's guide to starting a community garden suggests a core group of at least five interested families or a comparable group, meeting regularly, with at least three officers to set rules, assign plots, collect dues, and pay the water bill.

Find land, and get it in writing

The same guide recommends a site with at least 6 to 8 hours of sun a day, close to where members live. Short-list a few options. County tax records can tell you who owns a vacant lot, and you'll need the owner's permission before you dig.

Many groups lease land for a nominal $1 a year. The guide suggests seeking a lease of at least three years, so the work you put into the soil isn't lost, and including a hold-harmless waiver. Some landowners will also require liability insurance, so budget for it.

Water first

No water, no garden. Alabama Extension suggests asking your water provider to assess the site early; a lot with an existing hookup costs less to set up. Plan for about one hose bib for every four plots.

Test the soil for lead

City soil can carry lead from old paint, past buildings, and traffic. The EPA advises getting a lab test, through an accredited lab or your extension office, before growing food. Its gardening guidance recommends keeping gardens at least 10 feet from buildings, roads, and driveways, washing produce, peeling root crops, and removing outer leaves of greens. Root vegetables and leafy greens take up more lead than fruiting crops like tomatoes, peppers, and cucumbers.

EPA's 2014 gardening guidance groups soil by lead level. Under 100 parts per million is considered low risk with good hygiene. From 100 to 400, it recommends more care and fewer root crops. From 400 to 1,200, consider moving the garden or building raised beds and favoring fruiting crops and fruit trees. Above 1,200, raised beds or soil replacement are strongly recommended, and children shouldn't garden in the contaminated soil. About 24 inches of clean soil is generally considered an adequate cover.

Note that this is gardening guidance. In 2025, EPA lowered its separate residential screening level for lead at cleanup sites to 200 ppm. If your results come back high, talk to your extension office or health department.

Rules, plots, and agreements

Clear rules prevent most conflicts. Alabama Extension recommends written plot agreements signed by each gardener, fees, a waitlist, and a planting deadline, after which unplanted plots go to the next person on the list. Its suggested layout includes at least 15 plots, paths 3 to 4 feet wide, a fence, a shed, and a compost area.

• Who can have a plot, and how they're assigned.
• Fees and what they pay for.
• Workdays and shared chores.
• What happens when a plot is neglected.
• Rules on pesticides, water use, and harvesting from shared areas.

Budget and funding

Alabama Extension estimates a basic community garden at roughly $2,500 to $5,000 to start. Grants can help, but the guide warns that responses can take six months or longer, and some require a fiscal sponsor or 501(c)(3) status. Start small, with what you can fund now, and grow.
