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.

the info here about collard and kale says plant seeds Jan Feb and transplant March April for both.

Buy them on the internet - the seeds could come from anywhere in Australia even when purchased in QLD.

I did not start my collard, cabbage, seed in March - can I plant the seeds in the garden now in mid-July? Also, can I plant cauliflower in the garden from seed in July? I live in zone 6b. Thanks!!!
