What to do in Bend now
Bend is in cool-season grass country. Dates are typical for this spot, worked out from 23 years of weather at Redmond Airport; each status uses this year's soil estimates.
Cool-season: tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue
- Crabgrass pre-emergent Closed May 7 Typical: May 3 – May 202-inch soil held 55°F for a week from May 7, so crabgrass was sprouting. Next window: about May 3 – May 20, 2027.
- Seed or overseed Too late this fall Typical: Aug 19 – Oct 74-inch soil fell below 50°F on Oct 16; new seedlings rarely establish now. Seed next fall from about Aug 19, or dormant-seed once soil is near freezing so seed sprouts in spring.
- Late-fall feeding Last call · about 21 days Typical: Oct 17 – Nov 24Top growth has slowed but roots keep feeding until 4-inch soil cools to about 40°F, typically Nov 24. A final nitrogen feeding now goes to the roots.
Warm-season: bermudagrass, zoysia, St. Augustine, centipede, bahia
- Crabgrass pre-emergent Closed May 7 Typical: May 3 – May 202-inch soil held 55°F for a week from May 7, so crabgrass was sprouting. Next window: about May 3 – May 20, 2027.
- Seed or sod Wait for late spring Typical: Jun 24 – Aug 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 Jun 24.
- Fall pre-emergent (Poa annua) Germinating since Aug 30 Typical: By Aug 184-inch soil fell below 70°F on Aug 30, when annual bluegrass begins to sprout. A pre-emergent now only stops later flushes; plan to apply by about Aug 18 next year.
- Dormancy and last feeding Dormant since about Oct 13 Typical: Around Oct 74-inch soil has stayed under 55°F since Oct 13, so warm-season grass is going brown. It is too late to fertilize; feed again after spring green-up, once soil holds 65°F (typically Jun 24).

Which grass grows in Bend
Bend winters are cold enough (January averages 35°F) that cool-season grasses, mostly Kentucky bluegrass, tall fescue and perennial ryegrass, make up most lawns. They grow in spring and fall and slow down in summer heat.
Bend 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 Bend
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.

Bend questions
What is the soil temperature in Bend today? Our estimate for Nov 3 is 37°F at 2 inches and 39°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 Bend? Apply when 2-inch soil holds about 50°F and before it holds 55°F. That has typically been May 3 to May 20 in Bend. For 2026 the window closed on May 7.
Is it too late to overseed in Bend? Too late this fall. 4-inch soil fell below 50°F on Oct 16; new seedlings rarely establish now. Seed next fall from about Aug 19, or dormant-seed once soil is near freezing so seed sprouts in spring.
Is it too late to fertilize in Bend? Last call · about 21 days. Top growth has slowed but roots keep feeding until 4-inch soil cools to about 40°F, typically Nov 24. A final nitrogen feeding now goes to the roots.
When is the last frost in Bend? The last 32°F night of spring has typically come around Jun 16, and as late as Jun 22 in 1 year in 10. The first fall freeze typically arrives around Sep 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.
