My garden looked liked this...

This was a few months after I started gardening in this community garden. I was so ambitious, I must have had more than 30 different vegetables growing at one time. My plot is only 15x15.
One problem that you can encounter in a community garden is having a neighbor who lets his plot go. We are also dealing with a constant barrage of false garlic seedlings and nut grass. We grow food, not too much food. You also have to rotate crops in the small space. I tried it all...intensive gardening...only 6 months gardening...companion planting...summer gardening. Snails are a big problem here.

This is a school garden bed behind my class. There are five of these plastic lumber garden beds that are filled with soil. The kids love planting seeds and smelling the flowers. It is still a garden in progress.
