I have five beds of varying sizes and arrangements in my community garden plot. To really maximize my space, most of my beds ironically end up looking rather disorganized (consider my zigzags of peas over potato vines). But one bed is arranged into neat rows of alternating crops, and is now looking rather orderly after I weeded and put down a mulch of dried leaves:
The leaves will help keep the weed population down, and then at the end of the season I can just turn them under and they’ll enrich the soil. The rows are only six inches apart, but most of the greens will be finished by the end of June when the sweltering heat causes them to bolt. This will free up a lot of space for the beets and alliums, which are planted every other row. So my bed of greens will become a bed of roots!
