Collards

Garden Help > Vegetables

Large plant with very large green wavy leaves

Collards are a cool season vegetable grown for their large leaves. They are related to cabbage but do not form a tight head. Collards tolerate a wide range of warm to cold temperatures and, like many members of the cabbage family, will taste sweeter after a light frost.

When to plant

  • Direct seed or transplant in February to April or September to October; possibly May or August depending on weather and local conditions.
  • If growing your own seedlings, start the seeds 6 weeks before you want to plant.
  • For close plantings (6 to 12 inches apart), thin by cutting some plants at the soil level when crowding begins.
  • For wider spacing (15 to 18 inches apart), harvest lower leaves to allow the plants to continue growing and producing more leaves.

Harvest window

  • Harvest individual leaves after plants are well established, about two months after planting.
  • Some people prefer eating the younger inner leaves rather than the older, outer leaves.

Pest management

Collards are in the cabbage family, and pests are similar across the family.
