Collards are hardy, nutrient-packed greens that thrive in many home gardens. Choosing the right companion plants can help boost their growth, reduce pests, and improve yield. Likewise, planting the wrong neighbors can stunt growth or attract problems. Here’s how to make the most of your collard patch.

Why Companion Planting Works for Collards​


Collards are part of the brassica family, which includes cabbage, kale, broccoli, and cauliflower. They have similar nutrient needs and attract similar pests, such as cabbage worms and aphids. Companion planting works by:

  • Repelling pests with scent or leaf structure
  • Attracting beneficial insects like ladybugs and parasitic wasps
  • Maximizing space by pairing plants with different growth habits
  • Improving soil health through nutrient cycling and shade

TomatoesAttract pests that may also harm collards
StrawberriesAttract slugs, which also feed on collards
Other Brassicas (Cabbage, Broccoli, Kale)Compete for nutrients and attract the same pests
CornShades collards too much and competes for nitrogen

Planting Tips​

  • Rotate crops: Don’t plant collards in the same spot as other brassicas from the previous season to reduce disease risk.
  • Interplant flowers and herbs: Scents confuse pests and improve biodiversity.
  • Space correctly: Collards need 18–24 inches between plants for air circulation and healthy growth.


Final Thought:
By pairing collards with pest-repelling allies and avoiding competition-heavy crops, you’ll set yourself up for healthier plants, better yields, and fewer pest problems all season long.
