The Q&A Archives: St Augustine and brown patches

Question: We live near Dallas and planted St Augustine about 8 years ago in shaded area that Bermuda did not thrive in. The St Augustine spread nicely and looked great, but last year was plagued with large brown patches, mostly in one part of the lawn. Is there anything we should do now to try to keep it from repeating? Or should we look for another type of grass for that part of lawn?

Answer: I can't guess at which insect or disease did this without seeing a sample. However, I suspect it is either Take All Patch or chinch bugs. I suggest that you take a sample from the turf (cut a 4X4 inch plug with some roots and place it in a zip type bag) along with a photo of the plant in its growing location (if possible) to your County Extension Office to see if they can help diagnose the problem and recommend an appropriate course of action. Info on each of the above two problems is at the following two web pages: Take All Patch (click on ("Printable View") Chinch Bugs (click on ("Printable View") Thanks for the question. Please stop in again soon!
