Renovated backyard planting Princess 77 bermuda. It is coming up but so is all the crabgrass and other grassy weeds. Has only been 3 weeks but already trying to cut every two days to keep the weeds cut back enough to try to help the bermuda compete. I have heard of drive but was told by Pennington to spary use NOTHING for weed control for 60 days. Afraid by that time bermuda will lose the battle. Was also told by another reputable source that I do not want to use anything on the new seedlings for some time. BASF rep says that drive will take care of this problem. Anyone have experience? What should I do?
