If you are looking for a great way to save money and add perennial beauty to your landscape – then taking the time to overwinter your mums is a great place to start!

Mums are one of the first plants gardeners turn to for fall color, and it is easy to see why. These durable plants flower for weeks on end, and look incredible in pots, containers, and baskets,

But they can also be amazing when planted in the landscape. Even better, most mum varieties are more than tough enough to withstand the cold of winter, coming back to provide gorgeous autumn color year after year.

A Look At Hardy Mums

Although many folks consider mums (chrysanthemums) to be an autumn flowering annual, the majority of varieties for sale are actually quite hardy. Because of this, with just a bit of extra care, they can be grown quite easily as a perennial.

Mums are the go-to flower for fall decorating. But although many toss them away after they bloom, most varieties can actually be saved to live on for years.

It is important to note that not all mums can be overwintered and kept from year to year. There are actually two distinct types of mums, hardy and floral. In short, hardy mums can be kept, while floral mums cannot be saved.

The difference between the two is mainly in their roots. Floral mums have very shallow roots. Because of this, they simply can’t stand up to the rigors of wintertime when planted outside. The shallow roots quickly freeze, and the plant dies off in the process.

Selecting The Right Mums To Save

With all of that said, if you want to overwinter and save your mums, start by making sure to purchase hardy or garden mums, and not the floral mum variety.

Most nurseries and garden centers will have plants clearly marked. If not, as a rule of thumb, plants with smaller, more compact foliage and tightly wound blooms tend to be floral. Mums with larger stems, foliage, and blooms are most likely hardy.

Bringing Plants Indoors – How To Overwinter Mums

For first-year plants, the best method for success is to overwinter your mums indoors. It is extremely important to bring your mums inside before the first freeze occurs. As they sit in a pot or container, a single hard freeze can be enough to kill off the roots.

Before bringing your mum indoors, first, remove all of the spent blooms and flowering blooms that might be remaining. Not only can they create a mess indoors as they fall off, but this also helps the plant conserve energy for next year. A quick clipping with a good pair of hedge shears will make fast work of cutting off the blooms.

When bringing indoors, select a cool location that receives little light. A cool, dark basement or garage works great for this purpose. If not available, select the coolest, darkest room of the house.

By bringing the plant indoors, it allows the mum to go dormant, but not risk freezing out. And then as spring rolls around, you can safely plant the mums into the landscape.
