Plant Bermuda grass seed in Texas between late spring and early summer, when soil temperature reaches 65°F or higher and stays there consistently

Bermuda grass thrives in Texas heat and drought, but it germinates only when the soil is warm enough. In most of Texas, that window opens in May and closes by mid-July. If you plant too early, the seed sits dormant and rots. If you plant too late, the seedlings won't establish before fall stress arrives. Soil temperature matters more than air temperature—use a soil thermometer or check your local extension office's soil temperature map.

The best time varies by region. South Texas (San Antonio, Corpus Christi) can plant in late April. Central Texas (Austin, Dallas) should wait until mid-May. North Texas (Amarillo, Lubbock) typically plants in late May or early June. Coastal areas warm faster than inland areas at the same latitude.

Key Takeaways

  • Bermuda seed germinates only when soil temperature stays above 65°F, which in Texas means late May through mid-July depending on your region.
  • Prepare the soil by removing dead grass, breaking up compacted earth, and raking to expose bare soil—Bermuda seed needs direct contact with soil to sprout.
  • Spread seed at the rate your supplier recommends (usually 5 to 10 pounds per 1,000 square feet), then rake lightly so seed sits in the soil, not on top of it.
  • Water the seeded area lightly every day or every other day for the first two to three weeks until grass is 1 inch tall, then switch to deeper, less frequent watering.
  • Mow for the first time when seedlings reach 1.5 to 2 inches tall, cutting no lower than 1 inch to avoid scalping young plants.

Prepare the soil before spreading seed

Bermuda seed needs bare soil to germinate. If your lawn is patchy or thin, you do not need to remove all existing grass—just the dead thatch and compacted areas where seed cannot reach soil. Use a dethatcher or power rake to pull up dead grass and loosen the top half-inch of soil. Rake by hand afterward to break up clumps and create a fine seedbed.

If you are overseeding an existing lawn, mow it short (0.5 inches) a few days before seeding, then dethatch. If you are starting from bare ground or a dead patch, remove any debris, break up hard soil with a garden fork, and rake until the surface is relatively level and crumbly. Bermuda seed is small and needs direct contact with soil—it will not germinate sitting on top of thatch or mulch.

Test your soil pH if you can. Bermuda prefers slightly acidic to neutral soil (6.0 to 7.0 pH). Most Texas soils run neutral to alkaline, which Bermuda tolerates, but if your soil is very alkaline or very acidic, a soil test from your county extension office will tell you whether to amend it. Amendments take weeks to work, so do this before you seed.

Spread seed at the right rate and depth

Bermuda seed bags list a recommended seeding rate, usually between 5 and 10 pounds per 1,000 square feet. Measure your lawn or the area you are seeding, then calculate how much seed you need. Use a broadcast spreader (the spinning kind) or a drop spreader (the hopper kind). A broadcast spreader covers ground faster but requires more care to avoid bare spots and overlaps. A drop spreader is slower but gives you more control, especially near edges.

Spread seed in two passes at right angles to each other (one north-south, one east-west) to may support even coverage. Bermuda seed is tiny and straightforward to miss in spots. After spreading, rake lightly—just enough to work seed into the top quarter-inch of soil. Seed that sits on the surface will dry out and fail. Seed buried too deep will not reach sunlight and will not sprout.

Do not use a lawn roller after seeding. Rolling compacts soil and can bury seed too deep. Light raking is all you need.

Water consistently for the first three weeks

Bermuda seed needs constant moisture to germinate, but not standing water. Water lightly every day or every other day for the first two to three weeks. The goal is to keep the top half-inch of soil damp—not soggy, not dry. Early morning is the best time to water, before heat and wind dry the surface.

Germination usually begins within 7 to 10 days if conditions are right. You will see tiny green shoots. Keep watering on the same schedule until seedlings are about 1 inch tall and have developed a small root system. This usually takes 2 to 3 weeks. After that, switch to deeper, less frequent watering—water every 2 to 3 days, soaking the soil to 2 to 3 inches deep. This encourages roots to grow deeper and makes the lawn more drought-tolerant.

If a heat wave or dry spell hits during germination, you may need to water twice a day to keep the soil from drying out. Watch the forecast and adjust. Once seedlings are established, Bermuda is tough and forgiving—it is the first few weeks that are critical.

Mow when seedlings reach 1.5 to 2 inches tall

Do not mow until seedlings have developed a few leaves and are firmly rooted. This usually takes 3 to 4 weeks. When grass reaches 1.5 to 2 inches tall, mow for the first time. Set your mower to 1 inch—no lower. Cutting too short (called scalping) stresses young plants and can kill them. Bermuda is a warm-season grass and prefers to be mowed at 0.5 to 1 inch once it is mature, but young seedlings need more leaf area to photosynthesize and recover.

After the first mow, continue mowing every 5 to 7 days at 1 inch until the lawn is thick and established (usually by late summer). Then you can lower the mower to 0.5 inches if you prefer a shorter cut. Bermuda spreads by rhizomes and stolons (underground and above-ground runners), so regular mowing actually encourages it to fill in faster.

Fertilize lightly during establishment

Do not fertilize newly seeded Bermuda for the first 4 to 6 weeks. Young seedlings are sensitive to fertilizer burn, and excess nitrogen can promote disease. After seedlings are established and you have mowed a few times, explore a light fertilizer—something like a 10-10-10 or 15-0-15 formulation at half the recommended rate. Water well after fertilizing.

Once your Bermuda lawn is mature (by late summer or fall), you can follow a regular fertilization schedule. Most Texas lawns benefit from fertilizer in late spring and again in mid-summer. Your county extension office publishes fertilizer recommendations for Bermuda in your region—these are free and specific to Texas soils.

Handle common problems during germination

If you see bare patches after 3 weeks, the seed may not have made contact with soil, or it dried out during germination. Rake those areas lightly to expose soil, add a thin layer of seed, and water daily until new seedlings appear. You can overseed problem spots throughout the growing season as long as soil temperature stays above 65°F.

If seedlings look yellow or stunted, check your watering. Overwatering causes fungal disease and root rot. Underwatering causes drought stress. The soil should feel damp, not wet. If disease appears (gray or brown patches, slimy seedlings), reduce watering frequency and improve air circulation by mowing or removing nearby debris. Most seedling diseases clear up once the lawn dries out and grows stronger.

If weeds appear during the first month, do not use herbicide—it will kill seedlings too. Hand-pull weeds or wait until the Bermuda is thick enough to shade them out. Once your lawn is established, Bermuda's dense growth naturally crowds out most weeds.

Frequently Asked Questions

Can I plant Bermuda seed in fall or winter in Texas?

No. Bermuda seed will not germinate in cool soil. Fall and winter temperatures in Texas are too low. If you seed in fall, the seed sits dormant and often rots before spring. Spring and early summer are the only windows. If you need to establish grass in fall, consider cool-season seed like ryegrass, or wait until spring to seed Bermuda.

What is the difference between Bermuda seed and sod?

Seed is cheaper and takes longer to establish (4 to 8 weeks to a usable lawn). Sod is mature grass laid in rolls and is ready to use in 2 to 3 weeks, but costs significantly more. Seed is a good choice if you have time and patience. Sod is better if you need a lawn quickly or are filling a large bare area.

Do I need to water Bermuda seed during rain?

If rain falls during your watering window, you can skip that day's watering. But do not rely on rain alone—Texas weather is unpredictable, and a dry spell during germination will kill seedlings. Water on your schedule unless rain is heavy enough to soak the soil to 2 inches deep.

How long before Bermuda seed fills in bare spots?

Once seedlings are established and you start mowing, Bermuda spreads by runners and fills in gaps within 4 to 8 weeks. The warmer and more consistent your watering and mowing, the faster it spreads. By late summer or early fall, a well-maintained seeded area should look thick and uniform.

Can I seed Bermuda over existing dead grass?

You can overseed thin or patchy areas without removing all the dead grass, but you must dethatch first to expose bare soil. If the dead grass layer is thick (more than half an inch), seed will not reach soil and will fail. Dethatch, rake, then seed.
