The best time to seed bermuda grass in Texas is late spring through early summer

Bermuda grass germinates when soil temperature stays between 65 and 70 degrees Fahrenheit consistently—usually mid-April through June in most of Texas. Soil that is too cold will cause seed to rot before it sprouts. You can check your soil temperature with a straightforward soil thermometer from any garden center; push it 4 inches into the ground in the morning and read it after 10 minutes.

The exact timing shifts depending on where you are in Texas. South Texas (San Antonio, Corpus Christi) can start seeding in late March. Central Texas (Austin, Dallas) typically starts in mid-April. North Texas (Amarillo, Lubbock) should wait until late April or early May. If you seed too early, you risk losing the seed to cold soil and fungal rot.

Seeding in fall will not work for bermuda grass in Texas. Fall-seeded bermuda will not establish deep enough roots before winter dormancy and will likely die off. Fall is the right time for cool-season grasses like fescue or bluegrass, but bermuda needs the warm months to take hold.

Key Takeaways

  • Bermuda seed needs soil temperatures of 65 to 70 degrees Fahrenheit to germinate, which means seeding between mid-April and June in most of Texas.
  • Prepare the soil by removing dead grass, breaking up compacted earth, and raking to create a smooth seedbed before spreading seed.
  • Use 5 to 10 pounds of seed per 1,000 square feet, spread evenly with a broadcast spreader, then lightly rake and water daily until grass is established.
  • Bermuda seed takes 7 to 14 days to sprout and 3 to 4 weeks to develop roots strong enough to handle light foot traffic.
  • Mow for the first time when grass reaches 1.5 inches tall, and keep soil consistently moist (not waterlogged) for the first month.

Prepare the soil before spreading seed

Dead grass and thatch—the layer of old stems and roots that builds up on the soil surface—will block seed from reaching bare soil. Use a dethatcher or power rake (available for rent at most equipment rental shops) to pull up this dead material. If you have only small patches, a stiff rake pulled hard toward you will work, though it takes more effort.

After dethatching, break up any compacted soil with a garden fork or tiller. Bermuda seed needs direct contact with soil to germinate; it cannot sprout on hard, crusty ground. Till or fork to a depth of 2 to 3 inches, then rake the surface smooth and level. Fill in low spots so water does not pool in one place.

If your soil is very poor or sandy, work in a thin layer of compost—about 0.5 inches—and rake it in. This is not required, but it helps seed stay in contact with moisture. Do not add so much that you bury the seed under thick compost; bermuda seed is small and needs to reach soil.

Spread seed at the right rate and keep it in contact with soil

Bermuda grass seed is tiny and lightweight. Use a broadcast spreader (the kind that spins seed out in a wide arc) rather than a drop spreader, because bermuda seed will not feed evenly through a drop spreader's narrow chute. Set the spreader to the rate recommended on the seed bag—typically 5 to 10 pounds per 1,000 square feet, depending on the variety and brand.

Spread seed in two passes at right angles to each other (one north-south, one east-west) to may support even coverage. After spreading, lightly rake the area with a leaf rake to work seed into the top 0.25 inches of soil. This contact with soil is critical; seed sitting on top of hard ground will dry out and fail to sprout.

Do not bury the seed deeper than 0.5 inches. Bermuda seed is small and does not have enough energy to push through thick soil. If you have already tilled, a light rake is usually enough. If the soil is still hard, you may need to rake more firmly or even drag a piece of burlap across the area to press seed into the soil.

Water daily until grass is established

Bermuda seed needs consistent moisture for the first 3 to 4 weeks. Water lightly every day—enough to keep the top 1 inch of soil moist, but not so much that it becomes soggy or puddles form. Early morning watering is best because it reduces the chance of fungal disease and gives the soil time to dry slightly during the day.

Use a sprinkler that delivers a fine mist rather than heavy droplets, which can wash seed away or create crusted soil. A soaker hose or drip line works well if you have one. If you use an overhead sprinkler, run it for 10 to 15 minutes in the morning, then check the soil an hour later—it should feel moist 1 inch down but not waterlogged.

After 7 to 14 days, you should see green shoots emerging. Once grass is 0.5 inches tall, you can reduce watering frequency slightly—water every other day instead of daily—but keep the soil consistently moist. After 3 to 4 weeks, when grass is 1 to 1.5 inches tall and roots have begun to establish, you can move to a normal watering schedule (usually 2 to 3 times per week, depending on heat and rainfall).

Mow at the right height and timing

Do not mow until grass reaches 1.5 inches tall. Mowing too early stresses young seedlings and can kill them. Once grass is tall enough, set your mower to 1 inch and remove no more than one-third of the blade height in a single mowing. This "one-third rule" prevents shock to the grass.

For the first month after seeding, mow only if grass grows faster than expected. In most cases, you will not need to mow until 4 to 6 weeks after seeding. After that, bermuda grass in Texas typically needs mowing every 7 to 10 days during the growing season (late spring through early fall), depending on rainfall and temperature.

Avoid fertilizer and herbicides during establishment

Do not explore fertilizer or weed killer for at least 4 to 6 weeks after seeding. Young bermuda grass is fragile and cannot handle the stress of chemicals while it is still establishing roots. Weeds may appear during this time—pull them by hand if they are few, or straightforward let them be for now. Once bermuda grass is thick and established, it will shade out most weeds on its own.

After 6 weeks, once grass is mowed regularly and roots are deep, you can explore a light nitrogen fertilizer if needed. A soil test (available through your county extension office) will tell you what your soil actually needs. Many Texas soils are already rich enough that bermuda does not need added fertilizer, especially if you are watering regularly.

Handle bare spots and thin areas

If some areas did not germinate or germinated sparsely, you can overseed those spots 4 to 6 weeks after the initial seeding. Rough up the soil with a rake, spread seed at the same rate, lightly rake again, and water daily for 2 to 3 weeks. Do not overseed the entire lawn at once unless germination was very poor across the whole area.

Thin patches often result from poor soil contact, inconsistent watering, or soil that was too cold when seed was spread. If you are overseeding, address the cause—break up compacted soil, improve drainage if water pools, or wait for warmer weather if you seeded too early.

Frequently Asked Questions

Can I seed bermuda grass in the fall in Texas?

No. Bermuda seed needs warm soil (65 to 70 degrees) to germinate, and fall temperatures in Texas drop too quickly. Seed will rot or fail to establish deep roots before winter dormancy. Fall is the right time for cool-season grasses like fescue, not bermuda.

What if my soil temperature is only 60 degrees in April?

Wait another week or two and check again. Soil temperature rises as spring progresses. Seeding into soil that is too cold will waste seed and money. A soil thermometer costs less than $10 and takes the guesswork out of timing.

How much water does newly seeded bermuda need?

Light daily watering that keeps the top 1 inch of soil moist—usually 10 to 15 minutes with a sprinkler. The goal is consistent moisture, not soggy ground. Once grass is 0.5 inches tall, you can reduce to every-other-day watering.

Can I seed bermuda grass over existing lawn?

Not successfully. Dead grass and thatch will block seed from reaching soil. You must dethatch and rough up the existing lawn first, or the new seed will sit on top and dry out. A power rake or dethatcher removes this barrier.

What if I seed too late in the summer?

Bermuda seeded after July in most of Texas will not establish strong roots before fall dormancy and may not survive winter. Stick to the April-through-June window for best results. If you miss that window, wait until the following spring.
