Soil Requirements for Bermuda Grass

Bermuda grass is commonly used for lawns, parks, sports fields, golf courses and utility turf. It grows in the southern United States, India, Australia and South America. It's a perennial that spreads by rhizomes, seed and stolons. The stolons root at the nodes, then lateral buds produced at the nodes produce grass stems with leaves.

Soil Temperature

Soil temperature must be above 65 degrees F for the rhizomes, roots and stolons to grow and produce grass. The roots grow best in soil that is at least 80 degrees. If the soil is cooler, Bermuda grass grows slower, or goes dormant in winter.

Soil pH

Bermuda grass needs a soil pH of 6.0 to 7.0. If the soil is too acidic (below 6.0), lime is used to raise the pH of the soil to the proper pH. If the soil is too alkaline (over 7.0, which is neutral), sulfur is used to lower the pH of the soil. If the soil is in the proper pH, there is no reason to spread lime every spring. To determine whether your soil needs to be amended with lime or sulfur to adjust the pH, take a sample of the soil to your local county extension office, which will test the soil for you.

Soil Moisture

All plants require moisture to help absorb the nutrients in the soil. Bermuda grass prefers well-drained, moist soil, but tolerates some drought. During the spring, you might not need to water if your area gets plenty of spring rain. In the summer, when it tends to rain less, provide Bermuda grass with at least an inch of water per week. Watering deeply ensures that the deeper roots get the moisture and requirements needed for a healthy lawn, and encourages root growth.
