Brief history: 2 years ago l had established Fescue in my customers lawn after having sprayed it all with some round up. Sure 'nuff the bermuda came back the following year in some spots. This year, as you would expect, the bermuda expanded itself and took over more parts of the fescue lawn. Mid August this year, I sprayed the lawn with Prosecute and "knowing" it is better than the round up, i just "knew" it would take care of the bermuda and i'd be ready to seed the lawn again shortly after maybe one more checkup spray to ensure total kill out. Well, after rechecking a few times, it still has green stolons and we're approaching October. My people told me that they're not going to do this every year, and i totally understand! What's the best thing to do here? Maybe leave the lawn dead over the winter and let the cold weather kill the stolons and sew in the spring? BTW, i'm sewing fescue and the new bluegrass that has been adapted to the transition zone. Thanks in advance for your advise.
