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

Virginia is mostly USDA zone 7b (range 5b-8a). Dates below are derived from rhubarb's frost tolerance and Virginia's frost window — not generic national averages.

Rhubarb planting timetable for Virginia

Stage	When in Virginia	Anchor
Direct-sow outside	late March (March 25)	21 days before the last frost (mid-April)
First harvest (estimate)	late September (September 23)	~547 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 Virginia's climate shifts the rhubarb dates

Virginia's last spring frost averages mid-April and first fall frost late October, which sets the whole planting clock. Virginia runs from cool mountains through the Piedmont to a mild Tidewater, giving a long, varied mid-Atlantic season. Wait for warm soil — rhubarb stall in cold ground even after the air warms, so don't rush them out.

Rhubarb is planted as divisions or crowns in early spring while the soil is still cool, 2-3 weeks before the last frost; it is extremely cold-hardy and actually requires winter chilling to break dormancy (reliably hardy to zone 3, marginal in zones 9-10 where inadequate chilling reduces vigour). Do not harvest in year one; take only 2-3 stalks per plant in year two; harvest freely from year three onward, always leaving at least 3-4 strong stalks per crown. Never eat the leaves — rhubarb foliage contains toxic oxalates at harmful concentrations.

Frost-risk note

Don't plant before mid-April — a hard freeze can still set young plants back. In the western Appalachian highlands (zone 5b) the safe date runs a week or two later.

Regional variation within Virginia

the western Appalachian highlands (zone 5b) runs roughly 1-2 weeks behind the state average; the Tidewater and Hampton Roads coast (zone 8a) can plant 1-2 weeks earlier.

Frequently asked questions

When is the best time to plant rhubarb in Virginia?

In Virginia (mostly USDA zone 7b), direct-sow rhubarb late March (before the last frost, mid-April), and harvest from late September. Rhubarb 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 Virginia?

Most of Virginia sits in USDA hardiness zone 7b, with the state spanning roughly 5b-8a from the western Appalachian highlands (zone 5b) to the Tidewater and Hampton Roads coast (zone 8a). The last spring frost averages mid-April and the first fall frost late October.

Can you grow rhubarb in Virginia?

Yes. Virginia's dominant zone 7b supports rhubarb — the key is timing. Rhubarb 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 Virginia?

the western Appalachian highlands (zone 5b) runs roughly 1-2 weeks behind the state average; the Tidewater and Hampton Roads coast (zone 8a) can plant 1-2 weeks earlier.

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

Pair the post-frost slot with other warm-season crops — peppers, beans, squash, and cucumbers.
