Mowing: Achieving the Ideal Height

To keep Bermuda grass looking its best, it’s important to follow proper mowing practices. In the spring, set your mower to a 1-inch cutting height and remove debris before the grass turns green. During the growing season, maintain a mowing height of 1 inch for common Bermuda grass and 3/4 to 1 inch for hybrid Bermuda grass. Avoid allowing the grass to grow above 1 1/2 inches between mowings. If the grass becomes excessively high during a wet period, raise the mower and cut off one-quarter to one-half of the existing growth. Reel mowers are preferred for a clean cut, but rotary mowers can also be used if the blades are sharp and set to the appropriate height.

Fertilization: Nourishing the Grass

Proper fertilization is essential for maintaining healthy Bermuda grass. Apply 1 pound of nitrogen per thousand square feet two to three weeks after the grass turns green. Additionally, apply a complete fertilizer with a 3-1-2 or 4-1-2 ratio once or twice annually. For the remaining applications, use nitrogen sources such as urea (45-0-0) and ammonium sulfate (21-0-0). If the grass appears to be growing slowly and has a yellowish-green color, apply a nitrogen source every four to six weeks at a rate of 1 pound per thousand square feet.

Irrigation: Watering Wisely

Bermuda grass requires regular watering to thrive. In the absence of rainfall, apply approximately 1 inch of water per week. In sandy soils, apply about 1/2 inch of water every three to four days. Watering early in the morning is ideal, and you should avoid irrigating again until signs of wilt appear, such as folded or curled leaves. To determine if the soil is dry, probe it with your finger. Be cautious of shallow and frequent irrigations, as they can promote shallow rooting and encourage the growth of algae and moss.

Soil Cultivation: Keeping the Soil Healthy

Soil cultivation practices, such as vertical mowing and aerification, are essential for maintaining healthy Bermuda grass. Vertical mowing helps remove thatch (dead plant residue) and should be done about two to three weeks after the grass turns green. Aerification, which relieves compaction on heavily trafficked fields, should be done two to four times during the growing season. Use 3/4- to 1-inch-diameter tines to remove soil cores. These practices help improve drainage and promote healthier root growth.

Weed Management: Keeping Bermuda Grass Weed-Free

Successful weed management is crucial for Bermuda grass athletic fields. Regular aerification to relieve compaction and the use of herbicides that do not inhibit root growth are important strategies. Goosegrass, a major weed problem on athletic fields, can be controlled using oxadiazon (Ronstar). Preemergence herbicides are also effective for controlling crabgrass. For sedges and broadleaf weeds, several herbicides are available, including trifloxysulfuron (Monument) and 2,4-D mixtures. It’s important to follow the recommended application rates and timings for each herbicide.
