I plant my collards in September here in Montgomery Alabama should I be planting them at a different time? I do very well with them the late summer and early fall. I was not aware that they come back I always pull the plant and put them in a compost. Should I be doing that?

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!!!
