Question: My St. Augustine is yellowing and looking dry along my sidewalk and out in the middle of the lawn. What is wrong?

Answer: Suspect chinch bugs. They will show up in the hottest parts of the yard and in the middle of the summer. The grass will appear dry, but watering won’t bring it back around. You can see the b-b-sized insects with white diamonds on their wings flitting around in the interface between dying and healthy grass. If left untreated they are capable of killing the grass in large patches. Use a general-purpose turf insecticide to eliminate them. Check again in a week to be sure they are gone. They often will reappear summer-after-summer in the same parts of your yard.
