Growing Collard Greens from Seed

Growing Collard Greens from Seed

Mary Smith |

Collards are a southern favorite and absolutely delicious. Bonus, they are pretty easy to grow and can produce massive yields.

What are Collard Greens?

Collard is a group of certain loose-leafed cultivars of Brassica oleracea. Collards produce dark green leaves and tough stems that can be (often times are) removed before eating. The flavor of collard greens is a cross between cabbage and hearty kale, similar to Swiss chard. Collard greens are a southern staple. 


When to Plant Collard Seeds

Plant collard seeds from early spring to approximately 3 months before expected fall frost. If you live in a very mid climate, you might be able to grow them year round. Although they are a cool weather crop, they can tolerate heat.

Collards thrive in temperatures between 65°F and 75°F (18-24°C) and can withstand frost down to 25°F


Planting Collard Seeds

Sow seed ¼ to ½  inch deep in fertile, well drained soil. Keep the soil moist but not waterlogged.

Collard seed should germinate in 5 to 10 days at an optimal temperature of approx 75°F.


Collards can be grown in full sun but can tolerate partial shade.

For indoor planting: Start seeds indoors 6 to 4 weeks before the last frost in spring or 6 to 8 weeks before the first frost in fall.

It is a good practice to rotate crops every year or seasons. Avoid planting where cabbage family crops have grown recently.

Space plants 18 to 20 inches apart.

Harvesting Collard Greens

About 2 months after planting, you can start to harvest by clipping individual leaves. Collards are very hardy, and they flavor can improve into the late fall with light frost.

Love collards, such a healthy easy to grow green!!

Emily Norwick,

Bring born and raised in GA collards are a staple in our household, but I’ve never gotten around to growing them myself. They’ve always been a comfort food for me personally.
I’m going to try these this year since for once I’m not too late for cool weather crops!


I love collards and have grown them, but I’ve never grown them from seeds. I’ll have to try growing from seeds.


I just started planting my seeds (zone 10b) and I’m hoping I can keep the pests at bay! Fingers crossed.


We grow collards every year. LOVE THEM !
