7-day forecast and frost risk

Pre-emergent

Soil is 64°F at 4 inches (estimated soil temperature, not a station reading). Fall pre-emergent (annual bluegrass, winter weeds): window open as soil cools through the 70s and 60s.

Fertilizer window

Lawn region: Transition zone. Timing only; always follow the product label.

  • Bermudagrass (warm-season): Spring: Several weeks after the lawn is fully green (April–May) (about May 31 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).

Plant now

No vegetable planting windows are open this week.

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Oct 25: 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

Chance of a 32°F freeze after this dateDate
90% (early: most years still freeze after this)Mar 31
50% (the "average" last frost)Apr 15
10% (cautious: only 1 year in 10 freezes later)May 4

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

First fall frost odds

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 24521

Dates count from your average last spring frost (Apr 15) and first fall frost (Oct 25). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
