I live in Florida and have St. Augustine grass. Your email topic was timely as I want to go "organic" to keep my lawn looking acceptable for the HOA. I have used a lawn-service in the past to fertilize and for weed-control, but don't want to put pesticides on my lawn anymore. How do I deal with pest problems such as chinch bugs who love St. Augustine grass? How do I prevent them to begin with? Thanks.
