  • 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

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.

If you grow broccoli you can eat the leaves. Choose middle to small leaves after the head has been harvested. This will encourage tasty little heads at each lateral.

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 :)

Things that you eat during the winter have to be planted 10-12-16 weeks earlier, hence plant late summer autumn. Same with summer things, plant them late winter spring. This is dependent on the weather. I don't grow anything Nov to Feb because it is too hot and a storm could just smash my crop, ruining 2-3 months of effort on my part - sub tropical.
