I wonder if it's possible to overdo it with cover crops.
Last spring I created a new gardening space (about 4ft. x 15 ft.) First thing I did was plant a crop of a mixture of winter and annual rye. Then, when it got thick, dug it under. Then planted black eyed peas, then dug them under.
Finally now, I have a crop of thick clover going which I will leave thru the winter til next spring. I'll fork that under then and finally plant a crop. I wonder if that's too much? This is a spot that has never been gardened before.
