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

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

Collard Greens planting timetable for Virginia

Stage	When in Virginia	Anchor
Start seeds indoors	mid-March (March 18)	4 weeks before the last frost (mid-April)
Transplant outside	late March (March 25)	21 days before the last frost (mid-April)
First harvest (estimate)	early June (June 3)	~70 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 Virginia's climate shifts the collard greens 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. Sow early — collard greens bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Collards are one of the hardiest brassicas, tolerating temperatures down to about -7 °C once established, and one of the most heat-tolerant — unlike kale or cabbage, they continue producing in summer heat above 32 °C, which is why they are a staple in Zones 7–9 year-round. Transplant 2–4 weeks before last spring frost, or direct-sow where the season allows; for a fall harvest, start transplants 8–10 weeks before first fall frost. Succession-plant for continuous leaf harvest.

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 collard greens in Virginia?

In Virginia (mostly USDA zone 7b), sow collard greens indoors around mid-March, transplant outdoors late March (before the last frost, mid-April), and harvest from early June. Collard Greens 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 collard greens in Virginia?

Yes. Virginia's dominant zone 7b supports collard greens — the key is timing. Collard Greens 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?

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