7-day forecast and frost risk

The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 70825 load here. You can also open the NWS forecast for this ZIP.

Pre-emergent

Soil is 77°F at 4 inches (estimated soil temperature, not a station reading). Fall pre-emergent (annual bluegrass, winter weeds): not yet. Apply as soil cools toward 70°F (typically September to early October).

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 Apr 15 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

Prune now

No frost-timed pruning windows are open this week.

Your average first frost is Nov 26: 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 31
50% (the "average" last frost)Feb 28
10% (cautious: only 1 year in 10 freezes later)Mar 21

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 70825

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