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?

Plant Aug Sept - if really hot protect them from the sun for some of the day. Shade cloth or something.

Where can I buy collard green seeds or seedlings in South Afica? I live in Krugersdorp and Rustenburg.

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