I took an existing plot of Biologic Perennial and seeded in the Maximum to bring back the brassicas. I hit the plot lightly with a disc spread the seed and then rolled it. As of last weekend none of the Maximum had come up. I don' t know if the clover has choked it out or what but the clover that was left over from last year is doing very well and is probably 12" to 14" high. We have had plenty of rain and that probably contributed to the clover coming back so strong.
