Freezes are uncommon here, so frost-based timing is rough. Local extension calendars for frost-free areas use months.
Pre-emergent
Soil is 80°F at 4 inches. Fall pre-emergent (annual bluegrass, winter weeds): not yet. Apply as soil cools toward 70°F (typically October to early November).
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 Feb 27 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 17 (prior Dec) |
| 50% (the "average" last frost) | Jan 19 |
| 10% (cautious: only 1 year in 10 freezes later) | Feb 25 |
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 28 |
| 50% (the "average" first frost) | Dec 22 |
| 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 9 | Dec 6 |
| 32°F (freeze) | Jan 19 | Dec 22 |
| 28°F (hard freeze) | Jan 5 | Jan 1 (next year) |
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 78360
Dates count from your average last spring frost (Jan 19) and first fall frost (Dec 22). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
