I planted Buckwheat 2-3 times for my bees, when I kept bees. It grows fast, reseeds pretty good and you'll have to bush hog it a couple of times between now and dove season. It has a very short growing cycle. I never noticed many doves eating it, but it's a good soil builder.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
