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 12 (prior Dec) |
| 50% (the "average" last frost) | Jan 1 |
| 10% (cautious: only 1 year in 10 freezes later) | Jan 18 |
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 11 |
| 50% (the "average" first frost) | Dec 31 |
| 90% (late: most years have frozen by now) | Jan 16 (next year) |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Jan 10 | Dec 22 |
| 32°F (freeze) | Jan 1 | Dec 31 |
| 28°F (hard freeze) | n/a | n/a |
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 92258
Dates count from your average last spring frost (Jan 1) and first fall frost (Dec 31). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
