Need some guidance from the experienced. I have a 1 acre buckwheat plot in flower/turning seed that I want to seed to brassica mix for fall/winter food source. Would it be best to broadcast brassica seed into standing buckwheat - THEN mow or roll? Or mow, disc then broadcast seed? I've read on here that it's best to broadcast before a rain, but the other process I'm not sure of. Any help much appreciated.
