I have an area 3/4 acres.It hadn't been planted in about 4 yrs.I sprayed for weeds,Had the soil tested.I spread Lime & fertilizer.Tilled it in & then planted Clover/Chicory.Everything started coming up fast.This past late summer I noticed that a vine type weed was taking over and blocking out everything.I spot sprayed as much of the weed as I could see.Now 3/4 of my food plot is dead.My local farm service person suggested that in March I spread New Clover Seed over this area with the thought that the snow will push it down in the ground.Any suggestions.Would you till this area up & start over or Just spread new seed. Help,Roger
