re: Weird brown spots in St. Augustine

I just got back from a work trip and I believe chinch bugs are the culprit. There are a few new spots in the front and now about 5-7 in the back yard. I’m going to tractor supply and Home Depot to find a good pesticide, so I can wage war rather quickly.

I did do some reading and they recommend dethatching the lawn as part of the treatment. Several blogs I have read frown upon detracting St. Augustine because it doesn’t have rhizomes. However all of those blogs recommended aerating instead, in the late spring and early summer. I was going to wait until next year to aerate, but with Ronk’s approval, I think will go ahead.

What’s the boards opinion on dethatching St. Augustine vs Aerating?
