Freezes are uncommon here, so frost-based timing is rough. Local extension calendars for frost-free areas use months.

Pre-emergent

Soil is 79°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 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).

Prune now

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 dateDate

50% (the "average" last frost)Jan 30
10% (cautious: only 1 year in 10 freezes later)Mar 2

Most gardeners plant frost-tender crops (tomatoes, peppers, basil) after the 50% date, and closer to the 10% date for less risk.

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 77990

Dates count from your average last spring frost (Jan 30) and first fall frost (Dec 27). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
