7-day forecast and frost risk

The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 75937 load here. You can also open the NWS forecast for this ZIP.

Pre-emergent

Soil is 73°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 3 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).

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Nov 13: 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)Feb 26
50% (the "average" last frost)Mar 18
10% (cautious: only 1 year in 10 freezes later)Apr 8

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 75937

Dates count from your average last spring frost (Mar 18) and first fall frost (Nov 13). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
