Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.
How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.
| Planting Strategy | Last Spring Frost | First Fall Frost | Frost-Free Days |
|---|---|---|---|
| Conservative (safest) | Mar 17 | Dec 20 | 278 days |
| Cautious | Feb 24 | Dec 11 | 290 days |
| Average year | Feb 11 | Dec 4 | 296 days |
| Optimistic | Jan 28 | Nov 28 | 304 days |
| Aggressive (risky) | Jan 5 | Nov 21 | 320 days |
Not very — frost dates can vary by ±71 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Yes — growing seasons are getting shorter here (about 7.3 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.
