7-day forecast and frost risk

The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 30075 load here. You can also open the NWS forecast for this ZIP.

Pre-emergent

Soil is 70°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: Southeast (warm, humid). Timing only; always follow the product label.

  • Centipedegrass (warm-season): Spring: Not before mid-May (NC State); after full green-up (about May 10 here, using green-up about 3–4 weeks after your average last frost); Summer: Optional mid-summer feeding, especially on sandy coastal soils. Avoid: Early-spring feeding, frequent feeding and liming unless a soil test calls for it (centipede decline).

Plant now

  • Garlic: fall sowing Sep 28–Oct 26
  • Shallot: fall sowing Sep 28–Oct 26

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Nov 9: 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 5
50% (the "average" last frost)Mar 25
10% (cautious: only 1 year in 10 freezes later)Apr 12

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 30075

Dates count from your average last spring frost (Mar 25) and first fall frost (Nov 9). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
