Growing Collard Greens

Collards Greens (Brassica oleracea var. acephala) are leafy green vegetables rich in nutrients and a staple in Southern cuisine. With their robust flavor and versatility in the kitchen, growing collards in your garden can be a rewarding experience. In this comprehensive guide, we’ll delve into the details of harvesting from choosing the right varieties to harvesting and enjoying these nutritious greens.

1. Introduction to Collards:

Collards are a member of the Brassicaceae family, which includes cabbage and kale. These nutrient-dense greens are known for their large, dark green leaves and are packed with vitamins.

2. Choosing Collard Varieties:

Selecting the right collard greens to grow is essential for a successful harvest.

  • Georgia Southern Collards: A classic heirloom variety with large, dark green leaves.
  • Champion Collards: Another popular variety known for its tender leaves and resistance to bolting.

3. Selecting the Right Growing Conditions:

Collards thrive in specific growing conditions.

  • Climate: Collards are cold-tolerant and can be grown as both a spring and fall crop. They can tolerate light frosts.
  • Sunlight: Provide full sun for at least 6 hours a day, although collards can tolerate partial shade.
  • Soil: Well-draining soil rich in organic matter is ideal. Collards prefer a slightly acidic to neutral pH.

4. Starting Collards from Seeds:

Growing collards from seeds allows for a cost-effective and rewarding start to the cultivation process.

  • Seed Starting: Start collard seeds indoors 4-6 weeks before the last expected frost. Transplant seedlings when they have a couple of true leaves.
  • Direct Sowing: Collards can also be directly sown into the garden when the soil is workable in the spring or late summer.

5. Transplanting Collard Seedlings:

Transplant collard seedlings into the garden when they are sturdy and weather conditions are favorable.

  • Spacing: Plant collards 18-24 inches apart in rows with 24-36 inches between rows.

6. Watering Collards:

Collards require consistent moisture for optimal growth.

  • Watering Schedule: Keep the soil consistently moist, providing about 1-1.5 inches of water per week.
  • Mulching: Mulch around collard plants to retain soil moisture and suppress weeds.

7. Fertilizing Collards:

Feed collards with a balanced, all-purpose fertilizer to support their nutrient needs.

  • Fertilizer Application: Apply a balanced fertilizer at planting and side-dress with additional fertilizer during the growing season.

8. Companion Planting with Collards:

Planting collards alongside compatible companions can benefit their growth.

  • Companion Plants: Collards thrive when planted near beans, cucumbers, and herbs like mint and chamomile. Avoid planting them near tomatoes or peppers.

9. Protecting Collards from Pests:

Collards are generally hardy, but certain pests can pose a threat.

  • Pest Control: Use row covers to prevent cabbage worms and other pests. Handpick any pests that appear.

10. Harvesting Collards:

Harvesting collards at the right time ensures optimal flavor and tenderness.

  • Timing: Begin harvesting outer leaves when they reach a desirable size, typically around 60-75 days after planting.
  • Harvesting Technique: Use clean, sharp shears to cut leaves at the base, allowing the plant to continue producing.

11. Storing and Enjoying Collards:

Proper storage and culinary preparation maximize the enjoyment of collards.

  • Storage: Store collards in the refrigerator for up to two weeks. Keep them in a plastic bag to maintain freshness.
  • Cooking Methods: Collards can be sautéed, steamed, boiled, or added to soups and stews. Consider braising with flavorful ingredients like garlic and bacon.

12. Overwintering Collards:

In milder climates, collards can be overwintered for a continuous harvest.

  • Cold Protection: Protect collards from severe cold with row covers or cloches. Mulching around the plants provides additional insulation.

13. Seed Saving from Collards:

If you want to save seeds for future plantings, allow some collards to bolt and produce flowers.

  • Bolting Process: Collards bolt in response to warmer temperatures. Allow the plants to flower and set seeds.
  • Seed Harvesting: Harvest seeds when the pods turn brown and dry. Store them in a cool, dry place.

14. Health Benefits of Collards:

Collards are a nutritional powerhouse, offering numerous health benefits.

  • Rich in Nutrients: Collards are high in vitamins A, C, and K, as well as minerals like calcium and manganese.
  • Antioxidant Properties: The antioxidants in collards contribute to overall health and may help combat inflammation.


Growing collards allows you to enjoy a continuous supply of nutrient-packed greens. By following these guidelines, you’ll cultivate robust collard plants, enhancing your garden and providing a nutritious addition to your meals. Happy gardening and hearty eating!
