Yes and if they do - they are not as “tough” when it comes to mowing off. My experience is that a low rate of a good quality oats, allows the clover to establish well before the oats die and the clover over winters - without excess competition. Once established established. I am fine with over seed oats, rye, ww, brassicas, etc. into a clover patch.@Buckhunter10 Sounds like the point of using oats/black oats is they won’t overwinter vs fall planted rye?
