(Best months for planting Collards in USA - Zone 5a regions)

S = Plant undercover in seed trays. P = Plant direct in garden where they are to grow.


  • Easy to grow. Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 46°F and 86°F. (Show °C/cm)
  • Space plants: 16 - 20 inches apart
  • Harvest in 8-11 weeks.
  • Compatible with: Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile)
  • Avoid growing with: Climbing (pole) beans, tomato, peppers (chili, capsicum), eggplant (aubergine), strawberry, mustard
  • Collard leaves

Leafy, green vegetable - heat tolerant so a good substitute for kale and cabbage in tropical areas.

For best flavor and texture, leaves should be picked before they reach their maximum size.

Culinary hints - cooking and eating Collards

Slice and steam or use in stir-fry

For anyone in Adelaide, I got some collard seeds yesterday from Wilson's organics which is just off gouger st by the central markets. They are from Eden seeds who also have a website with heaps of different seeds. Hope this helps.

My collards are starting to grow what looks like seed pods at the top of the plant. How do I harvest the seeds?

I think they are bolting (going to seed). All the energy is going into stalk and producing seeds. I think they are done when this happens.

They are a loose-leafed brassica, a bit like a kale.

I would like to grow collards or collard greens. Where can I find seed or seedlings please. Are they the same as silverbeet or does silverbeet have the same or similar levels of Vitamin A?

Post a question, comment or tip about Collards

According to Wiki, Collards are also known as Borekale, and are a member of the Brassica oleracea Acephala Group along with broccoli, cauliflower and brussels sprouts. Collards and Kale although closely related which are genetically similar, but are not the same thing. If you want Collards, be certain that you are not getting Kale.
