Always repot a purchased potted mum plant when you get it home. They are usually root-bound, meaning that the roots are taking up the majority of the pot. Replant the mums in a container larger than the one it came in so the roots have room to spread out and breathe.

How long do potted fall mums last?

In the heat, all the flowers will fade in only a couple of weeks so you'll have to replace them faster if you want to keep up the colorful show through the season. If you wait until things cool off before setting out your mums, you'll be treated to blooms for up to 8 weeks once you have the plants in place.

Can you replant potted mums?

Transplant any potted mums in spring after frost danger has passed or in fall six weeks before the first expected freeze. These colorful fall flowers bloom most profusely when they receive all-day sunlight in a well-drained and moderately fertile bed.
