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 date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Jan 17 |
| 50% (the "average" last frost) | Feb 18 |
| 10% (cautious: only 1 year in 10 freezes later) | Mar 14 |
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 18 |
| 50% (the "average" first frost) | Dec 14 |
| 90% (late: most years have frozen by now) | Jan 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) | Mar 5 | Nov 26 |
| 32°F (freeze) | Feb 18 | Dec 14 |
| 28°F (hard freeze) | Jan 31 | Jan 2 (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 39571
Dates count from your average last spring frost (Feb 18) and first fall frost (Dec 14). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
