Prune now
No frost-timed pruning windows are open this week.
Your average first frost is Nov 3: 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) | Apr 4 |
| 50% (the "average" last frost) | Apr 17 |
| 10% (cautious: only 1 year in 10 freezes later) | May 3 |
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 20 |
| 50% (the "average" first frost) | Nov 3 |
| 90% (late: most years have frozen by now) | Nov 18 |
Light frost, freeze and hard freeze
| Threshold | Last spring (50%) | First fall (50%) |
|---|---|---|
| 36°F (light frost possible on clear, calm nights) | May 1 | Oct 22 |
| 32°F (freeze) | Apr 17 | Nov 3 |
| 28°F (hard freeze) | Apr 2 | Nov 16 |
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 02539
Dates count from your average last spring frost (Apr 17) and first fall frost (Nov 3). Half of years have a frost after the spring date, so give tender crops (tomatoes, peppers, squash) some slack.
