Diseases & Insects
The two common diseases are Dollar Spot Disease and Brown Patch Disease. Dollar Spot, which is most common in Bermuda grass, appears as a series of brown spots—each about the size of a silver dollar. To fix the problem, the affected area is fertilized. As its name suggests, the symptom of Brown Patch Disease is brown circular patches of grass. It is more common in St. Augustine and is usually treated with a fungicide.
Chinch bugs and white grubs are two prominent insects in the Houston area. Chinch bugs affect St. Augustine grass in the summer, usually starting in June and lasting until September. White grubs feed on the grass root systems, and their damage will become apparent mid- to late-August. These two insects will cause large areas of the lawn to turn brown and die if not properly treated.
