I live in the Houston Galveston area with an old St. Augustine lawn that has developed numerous dead circles. The blades have totally shriveled & died, but still are standing upright. The circles are no larger (at the moment) than 8″. It does not apprear to be brown spot or chinch bugs or resemble any other photos I have seen. I do have 2 rather large dogs, so I thought it could be urine, but I don’t think they go that much!
