This looks suspiciously like a garden from one of its' members in Beech Grove
This is from the seed swap page of the Middle Tennessee Plant Swap Facebook page. The link to their FB page is below as well as the link to the main group page. It is an open group and a bunch of great people to mix and learn with. While it is up in Spring Hill, you might be surprised how many folk are from the Bedford County area as well.
"Learn about multiple methods of seed starting without expensive equipment. A "Silent Demo" of the technique known as "wintersowing" will be on hand - including free instructions - as well as people who can give you tips and pointers. Doors open at 8:00 am to set up (tables and chairs provided). Bring a few seeds, or a lot! We will have some free seeds for you in any case. A special treat is in store after the potluck lunch at 11:00 or shortly before. Marty DeHart (of MTPS fame and also on The Volunteer Gardener program) will be speaking to us about seed starting and plant propagation at 11:30. Shortly after noon (or whenever we good and well get around to it or can tear ourselves away from Marty), we will have an auction! This will be a fun day all around! Bring seeds, cash, a covered dish, and hugs for friends old and new."
