What to do in Dallas now
Dallas is in warm-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Dallas Faa Ap; each status uses this year's soil estimates.
Cool-season: tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue
- Crabgrass pre-emergent Closed Feb 15 Typical: Feb 4 – Mar 32-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 4 – Mar 3, 2027.
- Seed or overseed Opens any day now Typical: Oct 26 – Dec 2Fall is the best time to seed. Start once 4-inch soil cools below 70°F, typically Oct 26, and finish while it is above 55°F, typically Dec 2.
- Late-fall feeding Soil rarely cools to 40°F Typical: Through winterRoots stay active through most winters here. Feed on the fall schedule your extension office gives for your grass, and avoid feeding a lawn that is dormant from drought.
Warm-season: bermudagrass, zoysia, St. Augustine, centipede, bahia
- Crabgrass pre-emergent Closed Feb 15 Typical: Feb 4 – Mar 32-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 4 – Mar 3, 2027.
- Seed or sod Seed or sod now Typical: Mar 21 – Oct 264-inch soil is 73°. Seed planted later than late summer has little warm weather left to establish before dormancy.
- Fall pre-emergent (Poa annua) Apply now Typical: By Oct 24Annual bluegrass (Poa annua) starts sprouting when 4-inch soil falls below 70°F, typically Oct 24. A fall pre-emergent must be down before then. Skip it if you plan to overseed with ryegrass.
- Dormancy and last feeding Expected about Dec 2 Typical: Around Dec 2Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 2. Make the last nitrogen feeding at least a month before that.
The last 60 days and the week ahead
Dallas soil is 9° warmer than normal for Nov 3, warmer than on 90% of those dates since 2005, and 10° warmer than a year ago.
The green line is our estimate of the daily average soil temperature 2 inches down, driven by temperatures at Dallas Faa Ap, 8.2 km from the city center. The dashed part runs the National Weather Service forecast through the same model. Hover or tap for any day.

Which grass grows in Dallas
With mild winters (January averages 48°F), most Dallas lawns are warm-season grasses such as bermudagrass, St. Augustine, zoysia and centipede. They grow through summer and slow or go dormant in winter.

Weekly 2-inch estimates for 2026 so far against 2025 and the normal for each week. The red lines mark 50°F, when crabgrass pre-emergent should be down, and 65°F, when warm-season seed sprouts well.

Typical lawn dates in Dallas
Each date is when the soil estimate (or the air, for freezes) crossed the threshold, year by year since 2005. “Early” and “late” are the 10th and 90th percentile years, so 8 years in 10 fall between them.

Where these numbers come from
There is no soil sensor in most cities, so we estimate it. Shallow soil follows air temperature with a lag of a few days, and runs a little warmer than the air in fall. We fitted that relationship to 190 USDA soil-sensor stations; on years held out of the fit, the estimate was off by 3.3°F on an average day, and it put the spring 55°F date within a median of 3 days.

Dallas questions
What is the soil temperature in Dallas today? Our estimate for Nov 3 is 71°F at 2 inches and 73°F at 4 inches, as a daily average. Early-morning soil runs a few degrees cooler than that, and afternoon soil warmer.
When should I put down crabgrass pre-emergent in Dallas? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 4 to Mar 3 in Dallas. For 2026 the window closed on Feb 15.
When can I seed bermudagrass in Dallas? Seed or sod now. 4-inch soil is 73°. Seed planted later than late summer has little warm weather left to establish before dormancy.
Is it too late to fertilize in Dallas? Expected about Dec 2. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Dec 2. Make the last nitrogen feeding at least a month before that.
When is the last frost in Dallas? The last 32°F night of spring has typically come around Feb 22, and as late as Mar 12 in 1 year in 10. The first fall freeze typically arrives around Dec 1.
Why 2 inches and 4 inches? Crabgrass and most weed seeds sprout in the top inch or two, so pre-emergent timing follows 2-inch soil. Grass seed and roots respond to the slightly steadier soil at about 4 inches.
How accurate is this? It is a model, not a probe in your yard. Expect about 3–4°F of difference on a given day; shade, slope, mulch and irrigation all move real soil. The dates and trends are more reliable than any single day.
