(Best months for planting Collards in New Zealand - cool/mountain regions)


  • Easy to grow.
  • Harvest in 60-80 days
  • 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 8°C and 30°C.
  • Space plants: 40-50cm

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
