Look for plots and places to garden, and that's step two. If you’re with a church, consider asking if there is a suitable spot on the property for communal space. Some churches might even allow you to use some land regardless of affiliation.
Other potential sites could be on a school campus, with permission, of course. Some interested gardeners may offer up a small corner of their yard, and there are even apartment complexes set aside space for tenants to garden. If you see some property and don’t know the owner, you can contact your local county tax assessor to learn that information.
Consider several factors when determining whether an area is suitable for cultivation. First, does the area receive enough sunlight? Thriving gardens require at least 6–8 hours of sun daily, but it needs more than the sun.
Second, sustainable gardens need a water source and should drain well. Ideally, they are flat and within walking distance to where people live. Also, these plots need to be free of debris. Finally, take soil samples to determine soil quality and pollutants — following acquiring permission from the landowner.
