Prune now
No frost-timed pruning windows are open this week.
Your average first frost is Oct 22: skip heavy pruning in the 6–8 weeks before it, because new growth may not harden off in time.

Last spring frost odds
| Chance of a 32°F freeze after this date | Date |
|---|---|
| 90% (early: most years still freeze after this) | Mar 30 |
| 50% (the "average" last frost) | Apr 13 |
| 10% (cautious: only 1 year in 10 freezes later) | Apr 28 |
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) | Oct 9 |
| 50% (the "average" first frost) | Oct 22 |
| 90% (late: most years have frozen by now) | Nov 2 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | Apr 25 | Oct 12 |
| 32°F (freeze) | Apr 13 | Oct 22 |
| 28°F (hard freeze) | Apr 2 | Nov 1 |
n/a means NOAA did not publish a date at that threshold for this station (usually because it rarely gets that cold).
