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

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

Radishes planting timetable for West Virginia

Stage	When in West Virginia	Anchor
Direct-sow outside	early April (April 4)	21 days before the last frost (late April)
First harvest (estimate)	early May (May 2)	~28 days from direct sow

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 radishes 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 — radishes bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Radishes are the fastest root crop — spring types mature in 22-30 days from direct sowing, making them ideal row-markers alongside slower crops. Sow 2-4 weeks before the last spring frost as soon as soil can be worked; they bolt and become pithy and peppery hot if left too long in warming soil. Succession-sow every 7-10 days for a continuous harvest; daikon and winter types sown in late summer take 50-70 days and tolerate heavier frost.

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 radishes in West Virginia?

In West Virginia (mostly USDA zone 6b), direct-sow radishes early April (before the last frost, late April), and harvest from early May. Radishes are half-hardy — young plants shrug off a light frost but not a hard freeze, so sowing can start a couple of weeks before the last spring frost.

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 radishes in West Virginia?

Yes. West Virginia's dominant zone 6b supports radishes — the key is timing. Radishes are half-hardy — young plants shrug off a light frost but not a hard freeze, so sowing can start a couple of weeks before the last spring frost.

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.
