Frost dates across West Virginia
State averages hide huge local spread — elevation, cold-air drainage, urban heat, and nearby water routinely move frost dates by two to four weeks within the same state. Median dates for representative West Virginia stations:
| City | Typical first frost | Typical last frost |
|---|---|---|
| Charleston | October 22 | April 18 |
| Morgantown | October 14 | April 28 |
| Elkins | September 26 | May 14 |

The West Virginia planting calendar
Every date below is computed from West Virginia’s own frost anchors — last frost ~May 1, first frost ~October 12 — using the standard week-count rules seed packets assume. Shift everything a few days for your microclimate (see the city table above).
| Garden task | Typical West Virginia date | The rule it comes from |
|---|---|---|
| Start onions & leeks indoors | February 20 | ~10 weeks before last frost |
| Start peppers & tomatoes indoors | March 6 | ~8 weeks before last frost |
| Direct-sow peas & spinach | March 27 | ~5 weeks before last frost |
| Plant potatoes | April 17 | ~2 weeks before last frost |
| Transplant tomatoes & peppers out | May 25 | ~1 week after the late frost date |
| Sow fall carrots (70-day) | July 19 | ~12 weeks before first frost |
| Sow fall spinach & lettuce | August 23 | ~7 weeks before first frost |
| Plant garlic | October 26 | ~2 weeks after first frost |
Two rules do most of the work: count backward from first frost for fall crops (a 70-day carrot needs sowing ~12 weeks out, because fall growth slows as days shorten), and count forward from the late last-frost date — not the median — for anything frost-tender going outside.
What dies at what temperature
“Frost” isn’t one event. Surfaces can frost with air temps as high as 36–37°F on calm clear nights; a freeze is 32°F; a hard freeze is 28°F and ends the season for anything unprotected. Crops check out at very different points along the way:
| Crops | Damage point | What it means |
|---|---|---|
| Basil, impatiens, coleus, sweet potato vine | 38–40°F | Damaged before an official frost even hits |
| Tomatoes, peppers, cucumbers, squash, beans | 32°F | Killed by the first light freeze |
| Lettuce, chard, cilantro, peas | 28°F | Shrug off light frost; done at a hard freeze |
| Broccoli, cabbage, carrots, beets | 25°F | Keep producing weeks past first frost |
| Kale, spinach, Brussels sprouts, parsnips | 15–20°F | Frost makes them sweeter — harvest all late fall |
The practical read for West Virginia: once you’re inside the September 25–October 28 window, the top two rows are living on borrowed time — while the bottom two rows are just getting started. Frost converts starches to sugars in kale, carrots, and parsnips; the sweetest harvests of the year come after first frost.
