7-day forecast and frost risk

The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 63136 load here. You can also open the NWS forecast for this ZIP.

Pre-emergent

Soil is 62°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 18 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

  • Garlic: fall sowing Sep 23–Oct 21
  • Shallot: fall sowing Sep 23–Oct 21

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Nov 4: 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 17
50% (the "average" last frost)Apr 2
10% (cautious: only 1 year in 10 freezes later)Apr 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 63136

Dates count from your average last spring frost (Apr 2) and first fall frost (Nov 4). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
