Do Mums come back the following year when planted?

Answer 1

In colder areas, it's best to plant perennial mums early in the season, so they'll form a good root system that can carry them through the winter.
"Flowering mums planted in the fall don’t consistently make it through the winter. The plants don’t have the time (or the inclination, since they are working hard on flowering) to extend their roots beyond the pot-bound root ball into the soil. The fragile roots are damaged by frequent cycles of freezing and thawing over the winter. Without a good root system, the plant dies."

If you have purchased mums this fall, go ahead & plant them, giving them some TLC. I've found that using soil that has a lot of organic compost added to it when planting mums in the fall & mulching them with chopped leaves & pine needles really increased their survival rate. When the threat of frost is over in the spring, don't forget to pull back the mulch.

Good Luck! Hope this helps.

Answer 4

They sure do. When they are all done blooming, you need to trim them to just an inch or so. And, they will be fine.
