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 14 (prior Dec) |
| 50% (the "average" last frost) | Jan 11 |
| 10% (cautious: only 1 year in 10 freezes later) | Feb 13 |
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 1 |
| 50% (the "average" first frost) | Dec 16 |
| 90% (late: most years have frozen by now) | Jan 18 (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 13 | Dec 1 |
| 32°F (freeze) | Jan 11 | Dec 16 |
| 28°F (hard freeze) | Dec 30 (prior Dec) | Dec 26 |
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 93105
Dates count from your average last spring frost (Jan 11) and first fall frost (Dec 16). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
