How to Treat Bermuda Grass

Maintain your Bermuda lawn grass so it is healthy and attractive.

Botanically called Cynodon dactylon, Bermuda grass is a low-lying perennial grass commonly grown in southern United States. This warm-season grass thrives in full sunlight to partial shade and tolerates dry spells as well. It is commonly grown in sports fields, golf courses, parks and homes because it withstands rough usage and traffic. Homeowners should follow a well-planned regimen of Bermuda grass care and maintenance so their lawn grass grows to form a lush, green carpet.

Apply herbicide over Bermuda grass in mid to late February or early to mid March, to kill weeds such as crabgrass that remain dormant during the winter months. Follow the manufacturer's directions for proper application.

Apply a post-emergence herbicide anytime during growing season to spot kill competing weeds. Administer a second application over the weed five to seven days after the first one. Keep in mind that weeds such as Dallis grass are very stubborn and require up to five applications to be eliminated.

Walk through your lawn and look for small brown spots that are a few inches wide. These spots indicate the presence of a fungal disease known as dollar spot. This disease spreads in moist or wet conditions, specially in late evening or night, so water the lawn early in the morning.

Apply a fungicide such as Daconil 2787 to the dollar spot, if it still remains after two weeks. Follow the label directions.

Fertilize your Bermuda grass lawn in mid to late May, or three weeks after it changes color from brown to green, to feed it essential nutrients and prevent fungal diseases. Use 1/2 to 1 lb. nitrogen-rich fertilizer for every 1000 square feet of lawn area and apply with a lawn spreader for an even distribution.

Water your Bermuda grass once a week, early in the morning, so at least 6 inches of soil get moist. Use a garden hose or automatic sprinklers for a timely and controlled watering session.

Mow the Bermuda grass down to 1 to 1 1/2-inches once or twice a week from June to November, and remove thatch every three weeks. Follow manufacturer’s directions for applying a winterizing fertilizer with a 4-1-6 ratio of nitrogen, phosphorus and potassium to keep your lawn grass green in fall. Allow the lawn to rest in the winter from December to early March, when it goes dormant.
