Fertilizer window
Lawn region: Gulf Coast and peninsular Florida. Timing only; always follow the product label.
- St. Augustinegrass (warm-season): Spring: About 2–3 weeks after full green-up (May in the Carolinas; earlier in Florida and south Texas) (about Mar 10 here, using green-up about 3–4 weeks after your average last frost); Summer: Light feedings June–August where local rules allow; Last: No later than about mid-September in the Carolinas, about 6–8 weeks before first frost elsewhere. Avoid: Feeding before green-up or late in fall (feeds weeds and favors large patch and cold injury).

Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Dec 29 (prior Dec) |
| 50% (the "average" last frost) | Jan 30 |
| 10% (cautious: only 1 year in 10 freezes later) | Mar 1 |
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 27 |
| 50% (the "average" first frost) | Dec 28 |
| 90% (late: most years have frozen by now) | Jan 27 (next year) |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Feb 17 | Dec 4 |
| 32°F (freeze) | Jan 30 | Dec 28 |
| 28°F (hard freeze) | Jan 17 | Jan 8 (next year) |
n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
