How Long do Mums Last?

How Long do Mums Last?

Short Answer: Mums, or chrysanthemums, are renowned for their vibrant autumn blooms, typically flowering for four to six weeks under optimal conditions. The best time to plant them is in the spring, which allows them to establish a strong root system and healthy growth before the blooming season in the fall. When planted in the spring, mums have ample time to acclimate to their environment, leading to a more robust and extended blooming period. It’s important to choose a location with well-draining soil and adequate sunlight to encourage maximum flowering. With proper care, including regular watering and deadheading, mums can provide a spectacular display of color in the garden from late summer through the fall.

Chrysanthemums are often available for sale at garden centers and grocery stores before summer ends. However, it’s important to know when the best time to plant them is and how long they bloom. Mums are a popular choice for fall outdoor decor as they bloom during the cooler autumn weather when other summer-flowering plants like zinnias and petunias are winding down.

It’s a great idea to have a few potted mums on your porch to transition from summer to fall. But, if you want your plants to last, it’s best to avoid buying them too early. Retailers may start selling mums well before fall begins, but it’s better to wait.

That depends on when they’re planted. Mums prefer cooler temperatures, which can be problematic if you buy them when they’re first available and it’s still getting to 90°F during the day. In the heat, all the flowers will fade in only a few weeks, so you’ll have to replace them faster to keep up a 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 the plants are in place. And if you get a few warm days here and there after cooler weather arrives, you can stash your mums in your house or garage until temps drop again.

Two other factors to consider are the type of chrysanthemum you’re buying and where you want to use it. If you’re hoping to use mums as an annual in a potted display or garden bed, you can opt for florist (or cutting) mums. Enjoy them until the blooms die off, and then compost them.

Hardy (or garden) mums are a different story. These mums are perennials if they’re correctly planted and given the proper care, making them a good choice for brightening your fall garden. They’re best planted in the spring once the ground is free of frost, giving them time over the summer to establish their roots in the soil before they become knockout bloomers in the fall.

How Do They Withstand Winter?

They likely won’t survive the winter in colder climates if you plant garden mums in the fall. Instead, you can try letting the plants go dormant in their pots and keeping them in a cold but frost-free indoor spot like a garage until the following spring. Then, you can plant the mums outside in your garden once the soil has warmed up. If your plant is still alive, you should soon see new growth from the roots.

For either type of mum, choose mums that are still budding and not in full bloom when picking out plants. You’ll be able to enjoy their flowers longer this way.

The bottom line to the question “How long do mums bloom, and when is the best time to plant mums?” is that there’s no “best” time, 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.
