Winter in Texas is a different animal than winter in, say, Minnesota. You’re not dealing with months of snow cover and deep freezes. But Texas winters bring their own set of challenges—unpredictable temperature swings, occasional hard freezes, persistent winter weeds, and the anxiety of watching your beautiful Bermuda lawn turn brown.

The truth is, winter is one of the most important seasons for Texas lawn care. What you do (and don’t do) between December and February has a massive impact on how quickly and beautifully your lawn greens up in spring.

Understanding Winter Dormancy in Texas

Most Texas lawns feature warm-season grasses: Bermuda, St. Augustine, Zoysia, or Buffalo grass. All of these go dormant when soil temperatures consistently drop below 55°F. The grass turns brown, top growth stops, and energy retreats to the root system.

This is completely normal and healthy. Dormancy is your grass’s survival strategy—it’s not dying, it’s conserving resources.

The timing of dormancy varies across Texas. In the Panhandle and North Texas, lawns typically go dormant by late November. In Central Texas, it’s usually December. Along the Gulf Coast and in the Rio Grande Valley, some lawns may never fully go dormant in mild winters.

Mowing During Winter

Once your grass is fully dormant, you can put the mower away. There’s nothing to cut. But during the transition into dormancy—which can stretch from November through December—continue mowing as long as there’s active growth.

For your final mow, set the blade to about 2 to 2.5 inches. This height:

  • Prevents matting during winter rain and occasional frost
  • Discourages voles and other rodents from nesting
  • Allows air circulation at the soil surface
  • Makes overseeded ryegrass (if applicable) easier to manage

If you’ve overseeded with ryegrass for winter color, you’ll continue mowing through winter at 2 to 2.5 inches whenever the ryegrass reaches 3 inches or taller.

Watering a Dormant Lawn

This is where many Texas homeowners go wrong. They either water too much (wasting money and encouraging disease) or not at all (stressing the root system).

Dormant grass still needs occasional moisture. The root system is alive and can suffer in extended dry periods. Here’s a practical approach:

  • Water deeply once every 2-3 weeks if there’s been no significant rainfall
  • Skip watering if it’s rained recently or if temperatures are below freezing
  • Water in the morning so any surface moisture evaporates before nightfall
  • Reduce sprinkler run times by about 50-60% from summer settings

If you’ve overseeded with ryegrass, water more frequently—about once per week, applying roughly three-quarters to one inch. Ryegrass has shallower roots and is less drought-tolerant than established warm-season grasses.

Pro tip: check your irrigation system before winter sets in. Run each zone and look for broken heads, leaks, or coverage gaps. In North Texas and the Panhandle, winterize exposed pipes and backflow preventers before the first hard freeze.

Winter Weed Prevention

Winter weeds are arguably the biggest headache for Texas lawn care between December and February. Without active grass growth to compete, weeds have the lawn all to themselves. Common culprits include:

  • Henbit – purple flowers, square stems, appears everywhere
  • Chickweed – low-growing, spreads rapidly in cool weather
  • Annual bluegrass (Poa annua) – light green clumps, extremely common
  • Clover – persistent and hard to eliminate once established
  • Rescue grass – tall, clumpy, and unsightly

The best defense is a pre-emergent herbicide applied in September or October, before these weeds germinate. If you missed that window, you’ll need to rely on post-emergent control.

For broadleaf weeds like henbit and chickweed, spot-treat with a selective broadleaf herbicide on days when temperatures are above 50°F. For grassy weeds like Poa annua, options are more limited—hand-pulling may be your best bet for small infestations.

One important caveat: if you’ve overseeded with ryegrass, many herbicides will damage the ryegrass too. Read labels carefully and consider tolerating a few weeds rather than risking your winter turf.

Fertilization: What to Do (And Not Do)

For dormant lawns without overseeding: Do not fertilize. Your Bermuda, St. Augustine, or Zoysia can’t absorb nutrients while dormant. Any fertilizer applied now will feed weeds or wash away. Save your fertilizer budget for the first application in spring when green-up begins.

For overseeded ryegrass: Apply a light fertilizer application about 4-6 weeks after germination, then again in late January or February. Use a balanced formula with moderate nitrogen—something like 15-5-10. Don’t overdo it; ryegrass is temporary and doesn’t need the same heavy feeding as your permanent lawn.

Dealing with Freeze Events

Texas is famous for its unpredictable winter weather. One day it’s 70°F, the next it’s 25°F with ice. These temperature swings are tough on lawns, but there are steps you can take:

Before a freeze:

  • Water your lawn lightly the day before a predicted freeze. Moist soil holds heat better than dry soil, providing a buffer for roots.
  • If you have newly planted grass or sensitive areas, cover them with frost blankets or old sheets.

After a freeze:

  • Don’t walk on frosted grass. Frozen blades are brittle and will snap, damaging the plant.
  • Don’t rush to assess damage. Brown, mushy grass after a freeze often recovers once temperatures warm. Give it time.
  • If temperatures stay above freezing for several days after a freeze event, water lightly to help the lawn recover.

For severe freeze events (like the infamous Texas winter storms), the recovery timeline is longer. Some grass varieties, particularly St. Augustine, are less cold-hardy than Bermuda and may suffer significant damage from prolonged sub-freezing temperatures.

Soil and Landscape Care

Winter is a great time for soil-related tasks that you’re too busy for during the growing season:

Soil testing: Send a sample to your local Texas A&M AgriLife Extension office. Results will guide your spring fertilization plan.

Compost topdressing: A thin layer (quarter inch) of quality compost spread over the lawn can improve soil biology even during dormancy. Microorganisms in the compost remain active in soil that stays above freezing.

Drainage assessment: After winter rains, observe where water pools on your lawn. These low spots should be addressed in spring with grading or drainage solutions.

Equipment Maintenance

With the mower parked for winter (unless you’re mowing ryegrass), take advantage of the downtime:

  • Drain or stabilize fuel in gas-powered equipment
  • Sharpen mower blades
  • Change oil and replace filters
  • Clean and organize your tool shed or garage

Having everything serviced and ready to go makes spring so much smoother.

Planning for Spring Green-Up

Spring green-up in Texas typically begins in late February in South Texas and progresses northward through March and April. Now is the time to plan:

  • First fertilization should happen 2-3 weeks after consistent green-up
  • Pre-emergent for summer weeds goes down when soil temperatures hit 55°F
  • Aeration is best done in late spring when warm-season grasses are actively growing

Patience Is Key

The hardest part of winter lawn care in Texas is resisting the urge to “do something” about the brown lawn. It’s tempting to throw down fertilizer, crank up the sprinklers, or start aerating—but most of these actions do more harm than good during dormancy.

Trust the process. Protect your lawn from weeds, water occasionally, and keep an eye out for problems. When spring arrives, a well-rested lawn greens up faster and stronger than one that was fussed over all winter.
