Question for Ronk, Crawdude concerning St. Augustine.

If I understand your question correctly, St Augustine does fill sparse areas of the lawn pretty quickly by sending out ”runners” (stolons) when the grass is healthy - certainly my experience in backyard lawn, when compared to my front yard centipede lawn.

If that is what you trying to achieve, more spreading to fill in sparse areas, maintain St Aug health by cutting it at the proper height and fertilize it on the recommended schedule. I’m trying say you should be getting both good spreading and grass height in a healthy St Aug lawn.

Cut it long (4 inches) and it will spread like a MFer and choke out weeds so fast. I didn't put down any pre emergent this year being lazy, had quite a few weed varieties this spring in Dallas with all the rain.

Have just been cutting at 4 inches, fertilizing at something like a 16-4-4 ratio (ish) at the first of the month starting May 1 and my yard is golden, zero weeds and literally haven't had to spray celsius once.

St. Augustine can be a little biotch but when its healthy, it's pretty great looking.

Also put down one treatment of Scott's disease X back in May.

Thanks to our two resident lawn guru's!
