RE: What about buckwheat?
I plan on planting some this year with sunflowers in the mix, in theory the buckwheat will grow quickly,flower then die back allowing the sunflowers to come up and flower.
I read this on an organic farming website somewhere so I will let you guys know how it goes. I have 50lbs of buckwheat seed so it should cover about an acre.
It is also supposed to make good cover for game birds and other small game as well.
