When winter arrives, many North Texas homeowners turn their sprinkler systems off completely. It feels like the right move—grass is dormant, growth has slowed, and water usage drops.
But here’s what surprises many homeowners: most winter lawn damage isn’t caused by cold weather alone. It’s caused by dry soil when cold temperatures hit.
Why warm winter days can be a problem
In North Texas, winter doesn’t mean consistently cold weather. We often see warm spells in the 60s and 70s followed by sudden drops into the 20s overnight. During those warm days, soil dries out—even though the lawn appears dormant.
When a hard freeze follows dry conditions, turf and sensitive plants are far more vulnerable to damage.
Why St. Augustine and Zoysia lawns suffer most
St. Augustine and Zoysia lawns are especially sensitive during winter dormancy. Over the past several years, dry soil combined with sudden temperature drops has been one of the most common reasons these lawns struggle to recover in spring.
How much should you water in winter?
You don’t need to water nearly as much as you do in summer. As a general rule:
- About 20% of your normal summer watering is enough in winter
- For spray heads in full sun, this is often around 10 minutes per zone
- The goal is soil moisture, not growth
The most important step before a hard freeze
When temperatures are expected to drop well below freezing:
- Water one to two days before the freeze
- Make sure the soil is not dry when cold air arrives
Moist soil holds heat better than dry soil, helping protect turf and landscape plants during temperature swings.
The payoff comes in spring
Lawns that maintain proper soil moisture through winter typically green up faster, recover more evenly, and require fewer repairs in spring.
