What to do in Little Rock now

Little Rock 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 Little Rock Ap Adams Field; each status uses this year's soil estimates.

Warm-season: bermudagrass, zoysia, St. Augustine, centipede, bahia

  • Crabgrass pre-emergent Closed Feb 20 Typical: Feb 16 – Mar 142-inch soil held 55°F for a week from Feb 20, so crabgrass was sprouting. Next window: about Feb 16 – Mar 14, 2027.
  • Seed or sod Wait for late spring Typical: Apr 20 – Oct 15Warm-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 20.
  • Fall pre-emergent (Poa annua) Germinating since Oct 21 Typical: By Oct 144-inch soil fell below 70°F on Oct 21, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Oct 14 next year.
  • Dormancy and last feeding Expected about Nov 19 Typical: Around Nov 19Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 19. Make the last nitrogen feeding at least a month before that.

Typical lawn dates in Little Rock

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.

Little Rock questions

What is the soil temperature in Little Rock today? Our estimate for Nov 3 is 68°F at 2 inches and 69°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 Little Rock? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 16 to Mar 14 in Little Rock. For 2026 the window closed on Feb 20.

When can I seed bermudagrass in Little Rock? 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 20.

Is it too late to fertilize in Little Rock? Expected about Nov 19. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 19. Make the last nitrogen feeding at least a month before that.

When is the last frost in Little Rock? The last 32°F night of spring has typically come around Mar 13, and as late as Mar 27 in 1 year in 10. The first fall freeze typically arrives around Nov 12.

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.
