Tennessee planting calendar

When to plant cabbage in Tennessee — sow, transplant & harvest dates

Tennessee is mostly USDA zone 7a (range 6a-8a). Dates below are derived from cabbage's frost tolerance and Tennessee's frost window — not generic national averages.

Cabbage planting timetable for Tennessee

Stage	When in Tennessee	Anchor
Start seeds indoors	early March (March 4)	6 weeks before the last frost (mid-April)
Transplant outside	late March (March 25)	21 days before the last frost (mid-April)
First harvest (estimate)	mid-June (June 13)	~80 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 Tennessee's climate shifts the cabbage dates

Tennessee's last spring frost averages mid-April and first fall frost late October, which sets the whole planting clock. Tennessee has a long, humid, warm season with mild winters. The eastern mountains run a zone cooler than the western lowlands. Sow early — cabbage bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Cabbage is one of the hardier brassicas, tolerating temperatures down to around −7 °C (20 °F) once established; light frost actually improves flavour. Start seeds indoors 6–8 weeks before last spring frost and transplant 3–4 weeks before last frost. Spacing affects head size — 30 cm (12 in) produces smaller, tender heads; 60 cm (24 in) allows large storage types. Heads will split if left in the field after maturing or after rain following drought stress. For fall crops, count back from first expected autumn frost — most varieties need 70–120 days.

Frost-risk note

Don't plant before mid-April — a hard freeze can still set young plants back. In the eastern Appalachian highlands (zone 6a) the safe date runs a week or two later.

Regional variation within Tennessee

the eastern Appalachian highlands (zone 6a) runs roughly 1-2 weeks behind the state average; the western Mississippi lowlands near Memphis (zone 8a) can plant 1-2 weeks earlier.

Frequently asked questions

When is the best time to plant cabbage in Tennessee?

In Tennessee (mostly USDA zone 7a), sow cabbage indoors around early March, transplant outdoors late March (before the last frost, mid-April), and harvest from mid-June. Cabbage 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 Tennessee?

Most of Tennessee sits in USDA hardiness zone 7a, with the state spanning roughly 6a-8a from the eastern Appalachian highlands (zone 6a) to the western Mississippi lowlands near Memphis (zone 8a). The last spring frost averages mid-April and the first fall frost late October.

Can you grow cabbage in Tennessee?

Yes. Tennessee's dominant zone 7a supports cabbage — the key is timing. Cabbage 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 Tennessee?

the eastern Appalachian highlands (zone 6a) runs roughly 1-2 weeks behind the state average; the western Mississippi lowlands near Memphis (zone 8a) can plant 1-2 weeks earlier.

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

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