Prune now
No frost-timed pruning windows are open this week.
Your average first frost is Nov 29: 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) | Feb 6 |
| 50% (the "average" last frost) | Mar 5 |
| 10% (cautious: only 1 year in 10 freezes later) | Mar 26 |
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 11 |
| 50% (the "average" first frost) | Nov 29 |
| 90% (late: most years have frozen by now) | Dec 26 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Mar 19 | Nov 15 |
| 32°F (freeze) | Mar 5 | Nov 29 |
| 28°F (hard freeze) | Feb 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 31313
Dates count from your average last spring frost (Mar 5) and first fall frost (Nov 29). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
