Pre-emergent
No soil reading near this ZIP. Typical extension timing for your region: spring late January to mid-February (south Florida: earlier; check local soil temps); fall 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 Mar 16 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).

No frost-timed pruning windows are open this week.
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) | Jan 6 |
| 50% (the "average" last frost) | Feb 5 |
| 10% (cautious: only 1 year in 10 freezes later) | Mar 7 |
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 23 |
| 50% (the "average" first frost) | Dec 17 |
| 90% (late: most years have frozen by now) | Jan 13 (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 25 | Nov 28 |
| 32°F (freeze) | Feb 5 | Dec 17 |
| 28°F (hard freeze) | Jan 26 | Jan 2 (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 70353
Dates count from your average last spring frost (Feb 5) and first fall frost (Dec 17). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
