There certainly are community gardens in the area. How interestingly that you'd ask because, just today, I put together a list to provide to 211 Big Bend and to the UF Extension Service so they can refer folks along to subscription community gardens (those are the ones where you can rent a plot in which to grow your own food).
Before I send you to my website to see the list of five Tallahassee-area subscription community gardens, I ought to share that there are two additional community gardens in the planning stages: one at the Walker Ford Community Center (Contact Daniel Dombrowski 891-1836) and one in Midtown at the Park at 9th and Terrace (Contact Aliki Moncrief 443-7609). I'm walking both these communities through the community garden development process. There are also whisperings of a community garden in Southwood.
Here's the link to the list of local community gardens
If none of these suit your fancy, and you find that you want to create a garden, take a look at the American Community Gardening Association's website
. They have great start-up resources, models, advice... and most important: a step-by-step check-list to follow. Let me know if you'd like to chat further on the subject. Community Gardens are my passion.
