I want to plant cow peas as a cover crop. Can I just buy a bag of black eye peas at the grocery store or are those seeds treated?
They will do fine. Of course if youwant them only as a cover crop, I would suggest the little brown peas marketed as field peas.

That's what I would do unless I had a feed and seed store nearby where I could buy the seed in bulk inexpensively.
