Timing is the difference between sod that roots in three weeks and sod you’re replacing next year. I’ve installed sod across Grayson and Collin Counties for over a decade. Here’s when to put it down — and when not to.
The short answer
Best window in North Texas: mid-April through early July, and mid-September through mid-October.
Acceptable but riskier: late July through August (heat stress), early November (frost risk).
Avoid: December through mid-March. Soil is too cold for warm-season grasses to root.
The rest of this post is the why behind those windows, plus how to handle each one if you’re already committed to a timeline.
Why timing matters for warm-season sod
Bermuda, Zoysia, and St. Augustine — the three sods we install in North Texas — are all warm-season grasses. They go dormant when soil temperatures drop below 55°F and they don’t push new root growth until soil hits a consistent 65°F or warmer.
New sod has to root into the soil below it within the first 14-21 days. That’s the window where if the roots don’t grab, the sod dies — no matter how much you water. Soil temperature, sun exposure, and watering frequency all drive that root strike.
Air temperature matters less than soil temperature. A 75°F afternoon in mid-March still has 50°F soil underneath, and that sod is going to sit there doing nothing until the soil warms up. Worse, cold roots are vulnerable to fungal issues.
April through early July — the sweet spot
By mid-April, North Texas soil is reliably warm. Daytime highs are in the 70s-80s, lows stay above 50°F, and rainfall in April-May helps establish without you having to baby the lawn.
This is the window we install most sod in. Roots strike within 10-14 days, new growth is visible within 3 weeks, and by July the lawn is fully established and ready to handle summer heat on its own.
The catch: this is also the busiest install season. If you want sod down by Memorial Day, schedule by mid-April. We typically book out 2-3 weeks during peak.
Late July through August — possible but riskier
Summer installs work if you have automatic irrigation and you can commit to watering twice a day for the first three weeks. Sod laid in 100°F heat needs aggressive moisture management — without it, the edges dry out and the sod curls before the roots have a chance to grab.
If you don’t have an irrigation system, summer install is a bad idea. Hand-watering 5,000 sq ft of new sod twice a day in Texas heat is a job. Most homeowners can’t keep it up for three weeks.
One workaround: install or upgrade irrigation as part of the sod project. We bundle these regularly because the upfront install handles its own watering for the establishment window.
Mid-September through mid-October — the second window
Fall is the underrated install season. Soil is still warm enough to push roots, daytime temps drop into the 80s, and rainfall picks back up. Sod installed in late September is fully established before the first hard frost in November.
Fall installs are also cheaper in some cases — most landscapers have more availability after the summer rush, so quotes tend to come in faster.
The downside: if you wait too long, you risk a frost hitting fresh sod that hasn’t fully rooted. Frost on unrooted sod is a near-guaranteed kill. October 15 is roughly the latest we’ll install without insisting on cold-protection plans.
November through March — avoid
Cool soil means no root growth. Bermuda goes brown-dormant from late October until April. Sod laid in this window will sit there until soil temperatures recover, and during that time it’s vulnerable to:
- Frost damage on exposed edges
- Soil settling and gaps between rolls
- Birds and animals pulling at unrooted seams
- Drying out from winter winds
If you absolutely have to install in winter — for a property closing, a builder deadline, a landscape contract — we use heavy mulch covers and recommend daily monitoring. But it’s a risk, and we always tell clients straight: it’s better to wait until April.
Specific timing by city
The whole I-75 corridor in our service area runs on roughly the same timeline. Slight variations:
- Denison, Pottsboro, and northern Grayson: Soil warms about 1 week later than south of the lake. Late April is more reliable than mid-April here.
- Sherman, Van Alstyne, Howe: Standard mid-April through October window.
- Allen, McKinney, Prosper, Celina: Soil warms 5-7 days earlier than Grayson. Mid-April is reliable, and the fall window stretches slightly later into October.
Frequently asked questions
Can I install sod in February if we have a warm winter?
No. Soil temperature is what matters, not air temperature. A 70°F February day still has 45-50°F soil underneath, which is too cold for warm-season grass roots. Wait for April.
What if my yard is bare and muddy right now (March)?
Best plan: grade the yard, add topsoil if needed, and wait for sod installation in April. In the meantime, a temporary cover crop or straw mulch keeps the mud down without committing to sod that’ll fail.
How long until new sod is fully established?
Roots strike in 10-14 days. Light foot traffic OK at 3 weeks. Full establishment — meaning the lawn can handle mowing, normal foot traffic, and reduced watering — takes 6-8 weeks during the warm season.
Do you offer cool-season grass options (fescue) for shaded yards?
No. Cool-season grasses don’t survive North Texas summers. For shaded yards we install St. Augustine sod, which handles 4-6 hours of filtered shade and still tolerates summer heat.
Will frost damage sod I install in October?
Fully rooted sod (4+ weeks old) handles frost without issue and just goes dormant. Unrooted sod (less than 3 weeks) can be killed by frost. That’s why we generally won’t install after October 15.
