What to do in Frisco now
Frisco is in the transition zone, where both cool- and warm-season lawns grow. Dates are typical for this spot, worked out from 23 years of weather at Mckinney Municipal 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 9 – Mar 62-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 9 – Mar 6, 2027.
- Seed or overseed Seed now · about 19 days left Typical: Oct 19 – Nov 224-inch soil is 70°, inside the 55–70°F range where tall fescue and bluegrass sprout fastest. The window typically closes around Nov 22.
- 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 9 – Mar 62-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 9 – Mar 6, 2027.
- Seed or sod Wait for late spring Typical: Apr 8 – Oct 19Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Apr 8.
- Fall pre-emergent (Poa annua) Germinating since Oct 20 Typical: By Oct 164-inch soil fell below 70°F on Oct 20, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Oct 16 next year.
- Dormancy and last feeding Expected about Nov 22 Typical: Around Nov 22Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 22. Make the last nitrogen feeding at least a month before that.

Typical lawn dates in Frisco
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. Read the methodology.

Frisco questions
What is the soil temperature in Frisco today? Our estimate for Nov 3 is 69°F at 2 inches and 70°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 Frisco? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 9 to Mar 6 in Frisco. For 2026 the window closed on Feb 15.
When can I seed bermudagrass in Frisco? Wait for late spring. Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Apr 8.
Is it too late to fertilize in Frisco? Expected about Nov 22. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 22. Make the last nitrogen feeding at least a month before that.
When is the last frost in Frisco? The last 32°F night of spring has typically come around Mar 16, and as late as Apr 15 in 1 year in 10. The first fall freeze typically arrives around Nov 10.
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.
