When to plant leeks in West Virginia — sow, transplant & harvest dates

West Virginia is mostly USDA zone 6b (range 5b-7a). Dates below are derived from leeks's frost tolerance and West Virginia's frost window — not generic national averages.

Leeks planting timetable for West Virginia

Stage	When in West Virginia	Anchor
Start seeds indoors	mid-February (February 14)	10 weeks before the last frost (late April)
Transplant outside	late March (March 28)	28 days before the last frost (late April)
First harvest (estimate)	late July (July 26)	~120 days from transplant

Dates are state-wide averages for the dominant zone. Local microclimates — elevation, urban heat, coastal moderation — can shift the window by 1-2 weeks. Use the frost-date calculator for a date tuned to your town.

Why West Virginia's climate shifts the leeks dates

West Virginia's last spring frost averages late April and first fall frost mid-October, which sets the whole planting clock. West Virginia is a mountain state where elevation drives the zone. River valleys are mild; the high Alleghenies are noticeably colder. Sow early — leeks bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Leeks are among the hardiest alliums — established plants tolerate temperatures as low as -10 °C, making them a reliable overwintering crop in zones 5–9. Start seeds indoors 10–12 weeks before last frost, transplanting pencil-thick seedlings into 15 cm (6-inch) deep holes or trenches to blanch the stems; backfill gradually as plants grow. Early-season varieties mature in around 90 days; late-season types take up to 150 days and deliver the best cold-hardiness for autumn and winter harvest.

Frost-risk note

Don't plant before late April — a hard freeze can still set young plants back. In the high Allegheny mountains near Davis (zone 5b) the safe date runs a week or two later.

Regional variation within West Virginia

the high Allegheny mountains near Davis (zone 5b) runs roughly 1-2 weeks behind the state average; the Ohio River valley near Huntington (zone 7a) can plant 1-2 weeks earlier.

Frequently asked questions

When is the best time to plant leeks in West Virginia?

In West Virginia (mostly USDA zone 6b), sow leeks indoors around mid-February, transplant outdoors late March (before the last frost, late April), and harvest from late July. Leeks are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

What USDA zone is West Virginia?

Most of West Virginia sits in USDA hardiness zone 6b, with the state spanning roughly 5b-7a from the high Allegheny mountains near Davis (zone 5b) to the Ohio River valley near Huntington (zone 7a). The last spring frost averages late April and the first fall frost mid-October.

Can you grow leeks in West Virginia?

Yes. West Virginia's dominant zone 6b supports leeks — the key is timing. Leeks are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

Does the planting date change across West Virginia?

the high Allegheny mountains near Davis (zone 5b) runs roughly 1-2 weeks behind the state average; the Ohio River valley near Huntington (zone 7a) can plant 1-2 weeks earlier.

What else can I plant in West Virginia around the same time?

The same early window suits peas, lettuce, spinach, and onion sets.
