The latest National Weather Service 7-day forecast and any Frost Advisory or Freeze Warning for 31548 load here. You can also open the NWS forecast for this ZIP.
Pre-emergent
Soil is 78°F at 4 inches. 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 29 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 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.
Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Feb 17 |
| 50% (the "average" last frost) | Mar 14 |
| 10% (cautious: only 1 year in 10 freezes later) | Apr 6 |
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
| Chance the first 32°F freeze has happened by this date | Date |
|---|---|
| 10% (early: 1 year in 10 freezes this soon) | Nov 5 |
| 50% (the "average" first frost) | Nov 25 |
| 90% (late: most years have frozen by now) | Dec 20 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Mar 30 | Nov 13 |
| 32°F (freeze) | Mar 14 | Nov 25 |
| 28°F (hard freeze) | Feb 21 | Dec 12 |
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 31548
Dates count from your average last spring frost (Mar 14) and first fall frost (Nov 25). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
