Well established clover plot that's been there for at least 8 years. Sometimes I think it's to established to drill grains into but come late winter the grains will be doing there part to feed the deer.
I just spray once a year and at a rate of 16 ounces per acre. Normally it is in June or as late as the first week in July which is later than most people but spring time is for turkey hunting and crappie fishing. IMO
