7-day forecast and frost risk

The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 78260 load here. You can also open the NWS forecast for this ZIP.

Pre-emergent

Soil is 73°F at 4 inches. Fall pre-emergent (annual bluegrass, winter weeds): window open as soil cools through the 70s and 60s.

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 13 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 28: 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.

90% (early: most years still freeze after this)Jan 29
50% (the "average" last frost)Feb 26
10% (cautious: only 1 year in 10 freezes later)Mar 17

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).

Vegetable planting calendar for 78260

Dates count from your average last spring frost (Feb 26) and first fall frost (Nov 28). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
