Bermudagrass is one of the most widely used turfgrasses in Texas. From football fields in Dallas, golf courses in San Antonio, to neighborhood lawns across Houston and Austin, this grass is everywhere. Texans love it for its toughness, drought tolerance, and thick green carpet during spring and summer.
But when winter sets in, many homeowners get worried. Suddenly, that vibrant green yard turns straw-brown.
Does this mean your grass has died? Should you water it? Fertilize it? Mow it? Or just wait for spring?
The good news is, bermudagrass in winter is simply dormant, not dead. It has adapted to Texas’s climate by slowing down in colder months to conserve energy.
But your role as a homeowner is important—what you do in the fall and winter directly impacts how healthy and green your lawn will be in spring.
This guide will give you everything you need to know about managing bermudagrass in winter in Texas—including preparation, mowing, watering, fertilization, overseeding, and weed control. Think of it as your seasonal lawn-care roadmap.
Why Bermudagrass Goes Dormant in Winter
To understand winter care, you first need to understand bermudagrass biology.
- Warm-season grass: Bermudagrass thrives when soil temps are 75–90°F. That’s why it grows so quickly in Texas summers.
- Dormancy trigger: Once night temps consistently drop below 55°F, growth slows dramatically. Eventually, the grass stops growing altogether and turns brown.
- Survival strategy: Dormancy is the plant’s way of protecting itself from cold damage. Energy is redirected to the roots instead of the blades.
In North Texas (Dallas, Fort Worth), dormancy typically starts by late October or early November. In Central and South Texas (San Antonio, Houston, Corpus Christi), lawns may stay green longer and enter dormancy closer to December.
By late March or April, as soil warms back up, bermudagrass “wakes up” and begins to green again.
Pre-Winter Preparation: The Fall Checklist
Think of fall as the training season for your lawn. The stronger your bermudagrass is in October, the easier it will handle winter dormancy.
1. Mowing Adjustments
- In early fall, gradually lower your mowing height to 1–1.5 inches.
- Avoid drastic scalping—just reduce little by little each cut.
- A shorter cut allows more sunlight to reach the crown and helps grass transition smoothly into dormancy.
2. Fertilizer Timing
- Stop high-nitrogen fertilizer about 6 weeks before your expected first frost.
- Switch to a fertilizer with higher potassium, which strengthens roots against stress.
- Nitrogen in late fall can push weak, frost-sensitive growth that won’t survive.
3. Weed Prevention
- Apply a pre-emergent herbicide in September or October. This prevents cool-season weeds like henbit and annual bluegrass from taking over while your grass rests.
- Choose products labeled safe for bermudagrass and follow directions carefully.
4. Overseeding Decision
- If you want a green lawn through the winter, plan to overseed with ryegrass in late September–early October.
- If you’re fine with the natural brown dormancy, skip this step.
Mowing Bermudagrass in Winter
Once bermudagrass is dormant, mowing takes a back seat.
- Frequency drops: You may not need to mow for 2–3 months.
- Tidy cuts only: If winter weeds sprout or overseeded ryegrass grows, you’ll still need occasional mowing.
- Avoid scalping: Cutting too low in winter exposes the crown to damage and increases weed risk.
Pro tip: Sharpen your mower blades in winter so you’re ready for spring’s heavy growth surge.
Watering Bermudagrass in Winter
Texas winters vary—some regions get mild rain, others are dry for weeks. So how much water does dormant bermudagrass need?
- Reduced needs: Dormant grass uses very little water compared to summer.
- Moisture check: If there’s no rainfall for 2–3 weeks, give your lawn about ½ to 1 inch of irrigation.
- Why water? Roots still need hydration to survive, especially in drought-prone West Texas.
- Avoid excess: Overwatering can cause fungal disease like spring dead spot.
In most of Texas, watering once per month in winter is enough—unless your region is unusually dry.
Fertilizing Bermudagrass in Winter
Many homeowners think lawns need fertilizer all year—but that’s a myth for warm-season grasses.
- Skip nitrogen: Fertilizing in winter wastes money and can harm bermudagrass. The grass simply won’t use it.
- Late-fall feed is key: If you applied a potassium-rich fertilizer before frost, you’ve already given roots what they need.
- Spring restart: Wait until the grass begins greening up (April in Texas) before applying a nitrogen fertilizer.
Rule of thumb: Feed the roots in fall, feed the blades in spring.
Weed Control in Dormant Bermudagrass
Weeds are the #1 nuisance for Texas lawns in winter. Since bermudagrass isn’t actively growing, weeds face little competition.
Common Winter Weeds in Texas Lawns
- Annual bluegrass (Poa annua)
- Henbit
- Clover
- Chickweed
- Dandelions
Control Methods
- Pre-emergents in fall: Prevent weeds before they sprout.
- Post-emergents in winter: Spot-treat any weeds that emerge.
- Hand pulling: Effective for isolated weeds in smaller lawns.
Weed-free lawns in winter = less competition for bermudagrass come spring.
Overseeding for Green Winter Color
Many Texans don’t like the brown dormant look. Overseeding offers a temporary solution.
Options:
- Annual ryegrass: Cheap, fast-growing, bright green. Dies out in spring.
- Perennial ryegrass: Darker green, finer blades, longer-lasting.
Benefits:
- Keeps lawn green all winter.
- Prevents erosion.
- Adds aesthetic curb appeal.
Drawbacks:
- Requires extra mowing and watering.
- May compete with bermudagrass during spring transition.
- Increases maintenance costs.
If overseeding, do it by early October so grass has time to establish before cold hits.
Protecting Against Frost and Freeze
Texas winters are unpredictable. One week may be 70°F, and the next may bring a hard freeze.
- Frost won’t kill bermudagrass—it simply accelerates dormancy.
- New sod is vulnerable: If you installed bermudagrass in late summer or fall, cover it with frost blankets to protect shallow roots.
- Foot traffic warning: Avoid walking on frosted lawns, as brittle blades snap and damage crowns.
Spring Transition: Waking Bermudagrass Up
By late March or April, soil temperatures rise and bermudagrass comes back to life.
What to Do in Early Spring:
- Wait to fertilize: Don’t fertilize until at least 50% of your lawn is green.
- Mow gradually: Start higher and lower the height over a few mowings.
- Pre-emergents: Apply a spring pre-emergent to stop summer weeds like crabgrass.
- Aeration: If your lawn feels compacted, aerate in late spring.
Patience is key—the greener your lawn gets naturally, the more effective your fertilizer will be.
Regional Differences Across Texas
Not all Texas lawns experience winter the same way.
- North Texas (Dallas, Fort Worth): Longer dormancy, more freeze risk. Overseeding is common.
- Central Texas (Austin, Waco, San Antonio): Moderate dormancy. Winter weeds are the main issue.
- South Texas (Houston, Corpus Christi, Rio Grande Valley): Short dormancy. Bermudagrass may stay partially green all winter.
- West Texas (Lubbock, Midland): Dry winters—occasional irrigation is critical.
Knowing your region helps fine-tune your winter lawn care routine.
Pro Tips from Texas Lawn Experts
- Rake leaves regularly in fall and winter. Leaves block sunlight and trap moisture, creating disease risk.
- Use mulch mowing if winter mowing is needed—nutrients from clippings return to the soil.
- Keep an eye out for pests like armyworms in early fall, which weaken bermudagrass before winter.
- Test your soil every 2–3 years. A soil test tells you exactly what nutrients to add in fall.
Final Thoughts
Caring for bermudagrass in winter in Texas is less about doing more, and more about doing the right things at the right time.
- Mow less.
- Water sparingly.
- Skip nitrogen fertilizers.
- Control winter weeds.
- Consider overseeding if you want green color.
If you prepare your lawn properly in fall and maintain these simple habits in winter, you’ll enjoy a healthier, thicker, greener bermudagrass lawn once spring arrives.

FAQs
Can bermudagrass stay green all winter in Texas?
In most of Texas, bermudagrass will go dormant and turn brown once temperatures drop consistently below 55°F. However, in the southernmost regions—like the Rio Grande Valley and coastal South Texas—mild winters sometimes allow the grass to keep a hint of green. For homeowners who want a consistently green lawn throughout winter, overseeding with ryegrass in early fall is the best option. It provides temporary color until bermudagrass greens up again in spring.
Should I dethatch bermudagrass in winter?
No, winter is not the right season for dethatching bermudagrass. Since the grass is dormant, it cannot recover from the stress caused by dethatching, which could leave the lawn thin and patchy. The best time to dethatch is in late spring or early summer when the grass is actively growing. That way, bermudagrass can heal quickly and fill in bare spots.
What happens if I fertilize in January?
Applying fertilizer in January won’t benefit dormant bermudagrass, because it isn’t actively absorbing nutrients. Instead, the fertilizer mostly feeds winter weeds like clover and annual bluegrass. Not only is this a waste of money, but it can also disrupt your soil’s balance and make weed problems worse. It’s best to wait until the grass begins greening up in spring before fertilizing.
Can I lay new bermudagrass sod in winter?
Installing new bermudagrass sod during winter is not recommended. Since the grass is dormant, the roots establish very slowly, making the sod more vulnerable to frost damage and weed invasion. For the healthiest start, plan to lay sod in late spring through summer, when warm soil temperatures help the roots spread and strengthen. This ensures your new lawn thrives going into the next winter.
How do I make my lawn green faster in spring?
The fastest way to encourage bermudagrass to green up is by maintaining proper winter care—controlling weeds, avoiding unnecessary nitrogen, and giving light irrigation during dry spells. Once temperatures rise, apply a balanced fertilizer, mow at the recommended height, and ensure your lawn gets at least 6 hours of direct sunlight daily. With these steps, your bermudagrass will transition out of dormancy more quickly and come back lush.
