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 3 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).

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) | Dec 28 (prior Dec) |
| 50% (the "average" last frost) | Jan 23 |
| 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) | Dec 18 |
| 50% (the "average" first frost) | Jan 9 (next year) |
| 90% (late: most years have frozen by now) | Feb 5 (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 6 | Jan 4 (next year) |
| 32°F (freeze) | Jan 23 | Jan 9 (next year) |
| 28°F (hard freeze) | Jan 16 | Jan 13 (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 70038
Dates count from your average last spring frost (Jan 23) and first fall frost (Jan 9). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
