Pre-emergent

Soil is 78°F at 4 inches. Fall pre-emergent (annual bluegrass, winter weeds): not yet. Apply as soil cools toward 70°F (typically September to early October).

Fertilizer window

Lawn region: South Central plains. Timing only; always follow the product label.

  • Bermudagrass (warm-season): Spring: Several weeks after the lawn is fully green (April–May) (about Apr 20 here, using green-up about 3–4 weeks after your average last frost); Summer: Every 4–6 weeks through mid-August (heaviest feeder of the group); Late: Light, low-nitrogen/high-potassium feeding about 4 weeks before first frost, or skip. Avoid: Heavy late-fall nitrogen (linked to spring dead spot).
  • Tall fescue (cool-season): Early fall: September (main feeding); Late fall: November, while still green; Late winter: Optional light feeding February–March. Avoid: Feeding after mid-spring and through summer in the transition zone (stress and brown patch).

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Nov 22: skip heavy pruning in the 6–8 weeks before it, because new growth may not harden off in time.

Spring-flowering shrubs are pruned right after their flowers fade, not by date. See the pruning guide.

JanFebMarAprMayJunJulAugSepOctNovDecLight blue: spring freeze risk (90% to 10%). Tan: fall freeze risk (10% to 90%). Dark lines: 50% dates.

Last spring frost odds

90% (early: most years still freeze after this)Feb 10
50% (the "average" last frost)Mar 5
10% (cautious: only 1 year in 10 freezes later)Mar 30

Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
