I'm scheduled to meet with the outgoing plot owner over the next few weeks and help her pull out all of the old/dead plants. What sort of overwintering soil amendments should I prepare? Should I try a cover crop? I'm in zone 7.
Red clover is a good cover crop, it puts nitrogen in the soil and you can make the blossoms into tea! Also it's nice for pollinators. Although you may have to spend some time weeding it out once you put your crops into the ground.
Garlic seems like a good thing to put into the ground now too, and maybe some daikon radish? They're pretty good for aerating soil, and of course they are yummy to boot!
I'm waiting to hear if there is space available at a community garden near me.. fingers crossed!
