When to plant kohlrabi in Georgia — sow, transplant & harvest dates

Georgia is mostly USDA zone 8a (range 6b-9a). Dates below are derived from kohlrabi's frost tolerance and Georgia's frost window — not generic national averages.

Kohlrabi planting timetable for Georgia

Stage	When in Georgia	Anchor
Start seeds indoors	early March (March 1)	5 weeks before the last frost (early April)
Transplant outside	mid-March (March 15)	21 days before the last frost (early April)
First harvest (estimate)	early May (May 9)	~55 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 Georgia's climate shifts the kohlrabi dates

Georgia's last spring frost averages early April and first fall frost early November, which sets the whole planting clock. Georgia runs from cool mountains to a warm coastal plain, with a long humid season. Most of the state gardens in zone 8. Sow early — kohlrabi bolt once daytime temperatures hold above 24 °C, so the earlier they go in, the longer the harvest.

Kohlrabi is a fast-maturing brassica that tolerates light frost down to about -4 °C but turns woody and pithy when daytime temperatures exceed 27 °C; transplant or direct-sow 3–4 weeks before the last spring frost for a summer harvest, or time a second sowing so plants mature in the cool days of early autumn. Harvest promptly when the swollen stem reaches 5–7 cm (2–3 inches) in diameter — larger bulbs become fibrous. Succession-sow every 3 weeks to extend the harvest window.

Frost-risk note

Don't plant before early April — a hard freeze can still set young plants back. In the Blue Ridge mountains in the north (zone 6b) the safe date runs a week or two later.

Regional variation within Georgia

the Blue Ridge mountains in the north (zone 6b) runs roughly 1-2 weeks behind the state average; the Atlantic coast around Savannah (zone 9a) can plant 1-2 weeks earlier.

Frequently asked questions

When is the best time to plant kohlrabi in Georgia?

In Georgia (mostly USDA zone 8a), sow kohlrabi indoors around early March, transplant outdoors mid-March (before the last frost, early April), and harvest from early May. Kohlrabi 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 Georgia?

Most of Georgia sits in USDA hardiness zone 8a, with the state spanning roughly 6b-9a from the Blue Ridge mountains in the north (zone 6b) to the Atlantic coast around Savannah (zone 9a). The last spring frost averages early April and the first fall frost early November.

Can you grow kohlrabi in Georgia?

Yes. Georgia's dominant zone 8a supports kohlrabi — the key is timing. Kohlrabi 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 Georgia?

the Blue Ridge mountains in the north (zone 6b) runs roughly 1-2 weeks behind the state average; the Atlantic coast around Savannah (zone 9a) can plant 1-2 weeks earlier.

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

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