I ploughed a couple of small fields at the end of May/ beginning of june. Glyphosate before, then rolled and cultivated them using a shallow spring tine cultivator and chain harrows. I then intended to create a stale seedbed with glyphosate. It had been very dry, but the rains started soon after cultivation. My question is, apart from chickweed in one area the weeds have not shot up, there are some seedlings but I would probably expect more after this time? Is it likely to be due to fewer seeds than i expected in the seedbed, ploughed at 6 inches and had not been ploughed in at least 70 years. Do they need more time? Do I just harrow again a few times and then plant?
