September is a swing month in the Texas garden world with the official arrival of Autumn later this month, which hopefully means the return of cooler weather. Despite lingering heat, this is still one of the better times of the year to be gardening, especially for landscaping plants.
You will want to pay attention to your lawn this month. The dry, hot weather encourages bugs which can really do damage on St. Augustine grass. Watch out for brown patch in the lawn. Fall is the prime season for this fungal disease. Symptoms appear as fairly circular areas of brown St. Augustine, which may expand outward and may green up again in the center. It is rarely fatal, just ugly. The dead leaves can be pulled off the green runners easily.
This month, apply fertilizer to keep your grass healthy and growing during frosts and cold snaps. It’s also a great time to take care of weeds that may be springing up from last fall.
