Winter in The Woodlands looks different from winter up north. We rarely see snow, and temperatures usually stay above freezing. But our lawns still shift into a slower gear from December through February. St. Augustine grass goes dormant when nighttime temperatures consistently drop below 55 degrees, while Bermuda grass turns brown even earlier. Understanding how these grasses behave during cooler months helps you avoid common mistakes and set up your yard for a strong spring.
Adjust Your Mowing Schedule
Once your grass stops actively growing, you can put the mower away for weeks at a time. St. Augustine typically slows down by late November, and Bermuda goes fully dormant even sooner. If you keep mowing on your summer schedule, you risk scalping the turf and exposing it to cold damage. When you do mow during winter, raise your blade height slightly. Taller grass blades protect the crown of the plant and help insulate roots during occasional freezes. Most homeowners in North Houston only need to mow once or twice between December and February, if at all.
Water Much Less Frequently
Dormant grass needs very little water. The cooler air and shorter days mean evaporation slows way down, and our clay soil holds moisture longer. Overwatering during winter invites fungal problems like brown patch and creates soggy conditions that stress grass roots. Cut back to watering once every two to three weeks, and only if we go through an unusually dry stretch. Check the soil before you water. If the top two inches feel moist, skip it. Your grass is resting, not growing, so it simply does not need the same hydration it demanded in July.
Hold Off on Fertilizer
Fertilizing dormant grass does more harm than good. The nutrients just sit there because the grass is not actively taking them up. Worse, pushing new growth during winter makes your turf vulnerable to freeze damage. Save your fertilizer applications for spring when soil temperatures rise above 65 degrees and your grass greens up naturally. That usually happens in late March or early April around here. Applying fertilizer too early wastes money and can encourage weeds that do grow in cool weather.
Watch for Winter Weeds
While your grass rests, cool-season weeds take advantage. Henbit, chickweed, and annual bluegrass pop up in lawns across The Woodlands during winter. These weeds actually thrive in the cooler temperatures that slow down your turf. If you applied a pre-emergent herbicide in fall, you should see fewer weeds now. For the ones that do appear, spot-treat with a post-emergent herbicide labeled for your grass type, or pull them by hand if there are just a few. Keeping weeds under control now means they will not go to seed and create bigger problems next year.
Prepare for Occasional Freezes
Most winters here stay mild, but we get a few nights that dip into the low 30s or even the 20s. St. Augustine grass can handle brief freezes, especially if it went into winter healthy and well-established. Avoid walking on frosted grass, since the blades are brittle and break easily. If a hard freeze is forecast, water your lawn the day before. Moist soil holds heat better than dry soil and provides some protection to grass roots. Do not panic if your St. Augustine looks brown or purple after a freeze. It usually recovers once temperatures warm up.
Plan Ahead for Spring
Winter is a good time to take stock of your lawn and think about what it will need when growing season returns. Walk your yard and note any bare spots, drainage issues, or areas where the grass struggled last year. Consider whether you need to aerate, topdress, or overseed come spring. Having a plan now means you can jump on those tasks as soon as the weather cooperates.
