That's a lot of tilling.i may try that sweet potato like you mentioned and some okra and tomatoes. Maybe something else green like beans or turnip greens.We had been getting cold and rain. Last days of rain fizzled out. Now the ground is dry enough to till. I've got 4-5 hours of tilling to to after noon tomorrow. That's a lot of walking. At least I have a Troybuilt electric start so I don't pull my shoulder out of joint. I already have it fired up and running. I have a bed builder attachment for building raised rows to plant on too. My onions, tomatoes, and sweet potatoes always go on a ridge of some kind.
