Knowing when to dethatch your lawn in Texas is the secret sauce to keeping your lawn looking its best. For warm season-grasses, late spring is your go-to time. If you’ve got cool-season grass, early fall is the way to go.
Timing is everything when it comes to dethatching. In this guide, we’ll dive into the details, helping you figure out the perfect time and approach to give your Texas lawn the TLC it needs.
Best time to dethatch lawns in Texas
Timing is everything when it comes to dethatching. The best time to dethatch your lawn in Texas depends on your specific grass type. Let’s dive in.
| Grass type | Best time to dethatch |
| Bermudagrass | Early spring to late summer |
| St. Augustinegrass | Mid-spring to late summer |
| Zoysiagrass | Early spring to late fall |
| Buffalograss | Late spring |
| Kentucky bluegrass | Early fall |
| Tall fescue | Early fall |
Pro Tip: Aim to dethatch during the early part of your grass’s dethatching window to minimize stress as the lawn recovers.
Warm-season grasses
1. Bermudagrass: Early spring to late summer
Bermudagrass starts actively growing in the spring. Dethatching during this time ensures that your lawn recovers quickly and takes full advantage of the warm, sunny days ahead.
For more tips on caring for Bermudagrass, check out this article: “Bermudagrass Maintenance Calendar for Texas.”
2. St. Augustinegrass: Mid-spring to late summer
St. Augustinegrass is a bit more sensitive to cold. Waiting until mid-spring ensures that the grass is fully out of dormancy and ready to grow vigorously, helping it bounce back from dethatching.
You can find more detailed care instructions in our article: “St. Augustinegrass Maintenance Calendar for Texas.”
3. Zoysiagrass: Early spring to late fall
Zoysiagrass has a slower growth rate compared to Bermudagrass, so it’s best to wait until the soil has warmed up enough to support new growth.
For more detailed guidance, see our article: “Zoysiagrass Maintenance Calendar for Texas.”
4. Buffalograss: Late spring
Buffalograss lawns don’t need to be dethatched often when well maintained. If the thatch is over 1/2 inch, dethatching in mid-May gives it plenty of time to recover before the heat of summer sets in.
Cool-season grasses
1. Kentucky bluegrass: Early fall
Kentucky bluegrass thrives in cooler temperatures. Dethatching in early fall, when temperatures are between 60 to 75 F, allows the grass to recover and strengthens it before the winter.
2. Tall fescue: Early fall
Like Kentucky bluegrass, tall fescue prefers cooler weather, and while it doesn’t produce much thatch, it can still benefit from dethatching every few years. Early fall dethatching gives it time to regrow and prepare for the winter months.
How to dethatch your Texas lawn and other info
You can use a rake or dethatching machine to remove thatch buildup in your Texas lawn. Not sure if your lawn needs dethatching? Dig up a small section (about 6 inches wide), and if the thatch layer is over 1/2 inch thick, it’s time to dethatch. For more details, check out this article: “How to Dethatch Your Lawn.”

FAQ about dethatching in Texas
Can I dethatch my warm-season Texas lawn in the summer heat?
Dethatching warm-season grasses during the peak of summer heat isn’t ideal. High temperatures and potential drought conditions can stress your lawn. Aim to dethatch during the early part of your grass’s dethatching window (see chart above) to give your lawn time to recover before the dog days of summer.
What should I do after dethatching my lawn?
After dethatching, your lawn will need some extra TLC to bounce back. Here are some key steps:
- Water deeply to help your lawn recover.
- Aerate the soil to improve soil compaction and boost root growth.
- Fertilize lightly to replenish nutrients and encourage new growth. For some great fertilizer options, check out: “The Best Lawn Fertilizers for Texas.”
Can dethatching help with lawn diseases?
Yes, dethatching can help reduce the risk of lawn diseases. A thick thatch layer traps moisture and creates a cozy spot for fungi and insects. By getting rid of excess thatch, you improve air circulation and reduce moisture buildup, making it harder for lawn diseases and pests to thrive. And that’s just one of the many benefits of dethatching your lawn.
When to call a pro
Dethatching is an essential part of maintaining a lush lawn in Texas. By regularly checking for thatch and dethatching at the right time, you can help your lawn thrive even in the challenging Texas climate.
