7-day forecast and frost risk

Pre-emergent
Soil is 69°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 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).

Prune now
No frost-timed pruning windows are open this week.
Your average first frost is Nov 5: 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) | Mar 12 |
| 50% (the "average" last frost) | Mar 30 |
| 10% (cautious: only 1 year in 10 freezes later) | Apr 14 |
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) | Oct 25 |
| 50% (the "average" first frost) | Nov 5 |
| 90% (late: most years have frozen by now) | Nov 21 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Apr 13 | Oct 27 |
| 32°F (freeze) | Mar 30 | Nov 5 |
| 28°F (hard freeze) | Mar 18 | Nov 17 |
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 27409
Dates count from your average last spring frost (Mar 30) and first fall frost (Nov 5). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
