- Bermudagrass (warm-season): Spring: Several weeks after the lawn is fully green (April–May) (about Apr 26 here, using green-up about 3–4 weeks after your average last frost); Summer: Every 4–6 weeks through mid-August (heaviest feeder of the group); Late: Light, low-nitrogen/high-potassium feeding about 4 weeks before first frost, or skip. Avoid: Heavy late-fall nitrogen (linked to spring dead spot).

Prune now
No frost-timed pruning windows are open this week.
Your average first frost is Nov 23: skip heavy pruning in the 6–8 weeks before it, because new growth may not harden off in time.
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 31 |
| 50% (the "average" last frost) | Mar 11 |
| 10% (cautious: only 1 year in 10 freezes later) | Apr 12 |
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 1 |
| 50% (the "average" first frost) | Nov 23 |
| 90% (late: most years have frozen by now) | Dec 25 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Apr 23 | Nov 1 |
| 32°F (freeze) | Mar 11 | Nov 23 |
| 28°F (hard freeze) | Jan 17 | Dec 17 |
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 95531
Dates count from your average last spring frost (Mar 11) and first fall frost (Nov 23). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
