When to Plant Collard Greens in Georgia
Published: April 24, 2026
Georgia gardeners in Zone 7b have a 38-week growing season for collard green (March 1 to November 22). Georgia's spring and fall windows both work well for collard green — some gardeners plant both successions for a long harvest. This guide gives exact dates for Georgia based on your local frost calendar.
Collard Green Planting Dates for Georgia
| Start seeds indoors | January 25–February 1 |
| Last frost (average) | March 1 |

Dates above assume Zone 7b, the most common zone in Georgia. Gardeners in cooler Atlanta (Zone 7b) plant 1–2 weeks later; warmer Savannah (Zone 9a) can plant 1–2 weeks earlier.
⚠ Direct sow or transplant collard greens 3–4 weeks before last frost. Extremely cold hardy — withstands temps to 15°F. Can be grown as a perennial in Zones 8+. Fall planting produces the best-flavored greens.
Growing Collard Greens in Georgia's Climate
Georgia's moderate Zone 7b climate is well-suited to collard green with minimal special accommodation. The standard transplant calendar works as written, and harvest windows line up with what seed packets recommend without adjustment.
Succession planting extends your collard green harvest significantly in Georgia. A second planting 3 to 4 weeks after the first gives you a backup in case of pest pressure and extends the total harvest window into early fall.
Common collard green pests to watch for in Georgia include Cabbage Worm and Aphid. The first line of defense is companion planting: Onion and Garlic planted nearby discourage several of these pests by confusing host-plant identification or repelling adults before they can lay eggs. Weekly garden walks in the early morning catch problems when they're still manageable.
