  • 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 8°C and 30°C. (Show °F/in)
  • Space plants: 40 - 50 cm 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.

Do collard greens have the same problems in the garden as cabbage? For instance- cabbage moths?

Keep a close eye on them and tell us what happens. Bst to plant when the moths aren't about, when there is little rain for insects and bugs to breed.

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

Are you planting at the right time? How fertile is your soil. Fertiliser, watering and full sunlight are required.

I've got some collard seeds and would love to grow them. I live in tassie and so far I always have best results growing Kale from autumn. Would it be the same for collards. Thanks :)
