Can You Divide Mums in the Fall

Answer: Don’t be tempted to divide your mums in the fall. They respond best to being split in the spring, just as they’re starting to grow. Dig up the plant. Discard the center of the clump and replant the vigorous outer roots.

Chrysanthemums (Chrysanthemum spp.) … Transplant spring mums after frost danger has passed, and transplant fall mums at any time in late summer or fall, at least six weeks before the first expected frost.

When should I put fall mums out?

The bottom line is that there’s not a “best” time to put out your potted mums, but you’ll get optimal plant performance in cooler weather. Mid- to late-September is ideal if you want to love your mums for as long as possible.
