I did a search, read through some posts and got some good ideas on eradicating Chickweed from Bermuda. Wanted to pose the question in a different manner. I have a 26,000 sq ft Bermuda lawn that we closely follow the Lesco recommended maintenance schedule on. We're coming up on the 2nd PRE-M application in a few weeks. This particular lawn has an abundance of Chickweed. I sprayed all I saw with Roundup on the last PRE-M application in February while the Bermuda was dormant. That was killed but now it's back with a force. Is there any Weed and Feed or anything else you would substitute for the next PRE-M application in April to help get rid of the Chickweed? This is the only weed problem we have here with the exception of a few wild onions. Crabgrass has never been an issue. It's just too much to spray with backpack sprayers. I don't want to lose this customer and I want to know if my only option is to hire someone with a broadcast sprayer to spray the entire yard. Also, is there any type of pre-emergent I could use in the future to prevent this problem? Thanks for any help.
