Ok, I appreciate all the suggestions. After considering some of your opinions I am going to do the following; -Spray with Quick Pro 2 times. This week and then the week after next. -Scalp down as low as possible. -I will till to create a good seed bed rather then just aerate for new seeding. -Seed at new lawn seed rate, fert, cover with pete moss. -Tell customer I will need to treat 2 times a year for the next 2 or 3 years to keep bermuda subsided. In this area and the existing lawn adjacent to this area. Im hoping after that, the lawn will be in the clear. Does this sound good?
