Answer: Since autumn is the prime flowering season for mums, I'd wait until they have finished flowering before digging and transplanting. You can replant anytime from December through April. Excellent companions for your mums include Ornamental Kale,
Ornamental Cabbage, Pansy, Viola, Dianthus, Lamium, Heuchera, Sage, Rosemary, Parsley, and snapdragons.
Enjoy your garden!
