Pre-emergent
Soil is 80°F at 4 inches (estimated soil temperature, not a station reading). 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 Mar 4 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) | Dec 29 (prior Dec) |
| 50% (the "average" last frost) | Jan 24 |
| 10% (cautious: only 1 year in 10 freezes later) | Feb 24 |
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 20 |
| 50% (the "average" first frost) | Jan 9 (next year) |
| 90% (late: most years have frozen by now) | Feb 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 6 | Jan 2 (next year) |
| 32°F (freeze) | Jan 24 | Jan 9 (next year) |
| 28°F (hard freeze) | Jan 15 | Jan 10 (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 34773
Dates count from your average last spring frost (Jan 24) 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.
