Q.After harvesting my cauliflower
After harvesting my cauliflower head, do I leave the remaining leaves on the plant? Will it regrow another cauliflower head? Do I need to pull out everything/root to replant for the next season or it will continue to produce?

You can dispose of the plant after you harvest the cauliflower head; it won't continue to produce. However, be sure to blanch the cauliflower before harvest to keep the head sweet and white in color.
