I have a big garden (60?x30) and a huge garden (145x25). Before I had the big garden, I would work half of the huge garden and planted the other half in some kind of cover crop. The asparagus bed was in the middle, so it was the dividing line.
Tip: Alfalfa is very difficult to get rid of, if you don't till it to death. If you don't plan to till your garden a couple times (at least!) or use some kind of herbicide, alfalfa will come back from the roots. Again. And again. There are STILL alfalfa plants coming up along the edge of one part of the huge garden.Plant buckwheat instead. Or cover rye.
I realized that if I planted something like butternut squash which takes over a LARGE area, I was out of space, so I decided to use the entire huge garden. Then I saw how much more light the area where I put the big garden got, and decided the stuff like tomatoes and peppers would go there.
I love the idea of part of the garden "resting" and being a place for compost. Good luck to those of you who do that. I bet it works well!
