Which legume to grow?
I'm hoping to add nitrogen into my raised beds. I have a crop of garlic in most of the beds, but am looking for something that will grow well after the garlic is out. Evidently garlic comes out in july. I've been looking at black eyed peas, because they are easy to get the seeds from the grocery store, and even if they go to seed they can still help the soil. This last one isn't a requirement, but it is convenient.
Looks like i have about 80-90 days of no frost, and have a small hoop house over the top of my beds if needed.
I'm wondering, what legumes am i not thinking of? I want to either til them into the soil by hand (using a plot to cut them at the ground, and then a fork to mix them into the soil) or throw them on the compost pile, either is fine. If i can get beans out awesome, if not, no worries.
Any suggestions? And why :)?
