Looking for non-invasive, non-vining annual full sun ground cover
I'm starting a garden in my backyard.
The soil is not up to par, so I plan to double-dig it and try to prepare the soil some this year, and then plant it next year.
One thing I've read is that it might be a good idea to plant some annual groundcover there this year to use the area and get it working, but then have some organic matter for next year that I can till into the soil when I go to plant next year.
I'm in SW Missouri. It gets pretty hot and dry here come August. I'm looking for some non-invasive, non-vining annual full sun ground cover that I can plant in this area once I get it dug up. Any suggestions?
