Most homeowners assume spring is the season for new grass. Around here, the calendar says otherwise. In Collin and Grayson County, September and October are the best two months of the year to install sod, and it is not close. The soil is still warm from summer, the air finally is not brutal, and your new lawn gets six to ten weeks of rooting weather before the first frost.
We install sod across McKinney, Allen, Prosper, Celina, Anna, Van Alstyne, Sherman, and Denison, and fall is when our best-looking lawns of the following year go in. Here is why, and how to time it right.
Why fall sod outperforms spring sod here
Warm soil, mild air. Sod roots respond to soil temperature, not air temperature. North Texas soil holds 70 to 85 degrees deep into October, which is exactly the range bermuda and zoysia roots grow fastest in. Meanwhile the afternoon air has backed off from the 100s, so the sod loses far less water while it establishes. In spring you get the reverse: cold soil, erratic swings, and grass that just sits there until May.
Less watering. New sod in July needs water constantly to survive its first two weeks. The same sod installed in late September needs noticeably less because evaporation drops with the temperature. Your water bill will show the difference.
Weed pressure collapses. Crabgrass and the rest of the summer weeds are done germinating by fall. Sod laid in September faces almost no competition while it knits down. Spring sod fights weeds from day one.
You skip the spring rush. Every landscaper’s phone rings in March. Fall projects book easier, and installs happen on schedule instead of in a six-week backlog.
The fall window, month by month
| Month | Verdict | What to know |
|---|---|---|
| September | Prime | Warm soil, cooling air. Sod roots aggressively. The best month of the year. |
| October | Very good | Still plenty of rooting time, especially the first half. Lawns knit down before dormancy. |
| November | Workable | Sod goes dormant after the first frost, usually around mid-November. It will sit brown and root slowly, then take off in spring. Fine for builders and patient homeowners. |
| December–February | Dormant installs only | Sod can be laid dormant, but establishment waits for spring. Water lightly, stay off it. |
Which grass for a fall install
Bermuda and zoysia both establish well in September. St. Augustine likes a little more runway before frost, so for St. Augustine we would rather install in early September than late October. If you are still deciding between them, our North Texas grass comparison walks through sun, shade, traffic, and maintenance for each.
What a fall install costs
Fall pricing is the same as any other season: most projects in our area run $1.20 to $3.00 per square foot installed, depending on grass type and how much prep the yard needs. Tear-out of a dead lawn costs more than sodding a graded builder lot. Our sod cost guide has a calculator, and there is a McKinney-specific cost breakdown if you want local numbers.
Watering new fall sod
Plan on keeping the top inch of soil consistently moist for the first two weeks, then tapering off as roots take hold. Fall makes this easier, but check your city’s watering rules first. Most cities on the NTMWD system run twice-weekly watering schedules, and many offer a new-lawn establishment variance for the first 30 days.

Common questions about fall sod
Can you lay sod in September in Texas?
Yes, and it is the best month for it in North Texas. Warm soil and mild air give sod ideal rooting conditions with less watering than a summer install.
How late in the year can sod be installed?
Actively growing installs work through about mid-October. After the first frost, usually mid-November here, sod goes in dormant. Dormant sod is normal practice on new construction; it greens up and roots in spring.
Will new sod survive a North Texas winter?
Yes. Bermuda and zoysia are fully winter-hardy here. Sod that roots in fall comes back thicker in spring than sod planted the following March, because it spends winter with an established root system.
Is fall sod cheaper?
Sod farm prices are steady year-round, so the per-foot price is similar. What fall saves you is water, weed treatment, and scheduling headaches.
