How to deal with my Chrysanthemum's.
I bought a few Chrysanthemum plants in pots this summer. The pots were about 9" and the plants were bush like up to about two feet wide. They have now finished flowering and the flowers are brown. I would like to see if I can keep them alive through the winter so do I just trim the dead heads off or do I prune the plants down to about six inches or so high?
