  • 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 (can grow beside): Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile)
  • Avoid growing close to: 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. Also recommended for health reasons.

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

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?

Hey there, you can buy the seeds online.

But whereabouts online? I have yet to find it available online in NZ and importing it from overseas is likely to run foul of our immigration laws.

Hi Paul The Koanga Institute have seeds available they call it the Dalmatian cabbage. I think i have seen it advertised in either the Egmont seeds catalogue or the Kings seeds catalogue. All three have on line catalogues. Collards are a type of Brassica. Regards Barry

My collard seeds did germinate but they aren't growing beyond the first set of leaves. What his happening?
