What to do in Shreveport now

Shreveport is in warm-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Shreveport Ap; each status uses this year's soil estimates.

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

  • Crabgrass pre-emergent Closed Feb 15 Typical: Feb 4 – Feb 262-inch soil held 55°F for a week from Feb 15, so crabgrass was sprouting. Next window: about Feb 4 – Feb 26, 2027.
  • Seed or sod Wait for late spring Typical: Mar 23 – Oct 21Warm-season seed needs 4-inch soil at 65°F or more, and seedlings need the rest of summer to establish. Next window opens about Mar 23.
  • Fall pre-emergent (Poa annua) Germinating since Oct 21 Typical: By Oct 204-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 20 next year.
  • Dormancy and last feeding Expected about Nov 27 Typical: Around Nov 27Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 27. Make the last nitrogen feeding at least a month before that.

The last 60 days and the week ahead

Shreveport soil is 8° warmer than normal for Nov 2, warmer than on 90% of those dates since 2005, and 11° warmer than a year ago.

The green line is our estimate of the daily average soil temperature 2 inches down, driven by temperatures at Shreveport Ap, 3.7 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 Shreveport

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

Typical lawn dates in Shreveport

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.

Shreveport questions

What is the soil temperature in Shreveport today? Our estimate for Nov 2 is 70°F at 2 inches and 71°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 Shreveport? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 4 to Feb 26 in Shreveport. For 2026 the window closed on Feb 15.

When can I seed bermudagrass in Shreveport? 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 Mar 23.

Is it too late to fertilize in Shreveport? Expected about Nov 27. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 27. Make the last nitrogen feeding at least a month before that.

When is the last frost in Shreveport? The last 32°F night of spring has typically come around Mar 3, and as late as Mar 24 in 1 year in 10. The first fall freeze typically arrives around Nov 21.

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.
