What to do in Redding now

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

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

  • Crabgrass pre-emergent Closed Mar 3 Typical: Feb 7 – Mar 152-inch soil held 55°F for a week from Mar 3, so crabgrass was sprouting. Next window: about Feb 7 – Mar 15, 2027.
  • Seed or sod Wait for late spring Typical: Apr 26 – Oct 11Warm-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 26.
  • Fall pre-emergent (Poa annua) Germinating since Oct 19 Typical: By Oct 94-inch soil fell below 70°F on Oct 19, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Oct 9 next year.
  • Dormancy and last feeding Expected about Nov 20 Typical: Around Nov 20Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 20. Make the last nitrogen feeding at least a month before that.

Which grass grows in Redding

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

Redding soil through the year

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 Redding

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.

Checked against a real sensor

Measured nearby: 46°F at 2 inches on Nov 3, at the USDA SCAN site “French Gulch”, 18 miles away.

Our estimate for Redding on Nov 3 is 53°F; the sensor read 50°F at 4 inches against our 55°F. Sensor sites sit in open, unwatered ground outside town, so they often run a few degrees apart from city lawns; use them as a check on the trend.

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.

Redding questions

What is the soil temperature in Redding today? Our estimate for Nov 3 is 53°F at 2 inches and 55°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 Redding? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been Feb 7 to Mar 15 in Redding. For 2026 the window closed on Mar 3.

When can I seed bermudagrass in Redding? 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 26.

Is it too late to fertilize in Redding? Expected about Nov 20. Warm-season grass slows and browns once 4-inch soil stays under 55°F, typically Nov 20. Make the last nitrogen feeding at least a month before that.

When is the last frost in Redding? The last 32°F night of spring has typically come around Mar 4, and as late as Apr 12 in 1 year in 10. The first fall freeze typically arrives around Nov 24.

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.
