The Basics
On average, cut chrysanthemums will last 7 to 14 days in a clean vase with proper care. Some varieties may start to fade sooner, while others can look fresh for 3 weeks or more
So chrysanthemums are one of the longest lasting cut flowers you can buy. Much longer than more delicate roses lilies, or tulips.

Factors That Influence Longevity
Several key factors work together to determine just how long cut chrysanthemums will last in your home:
-
Flower Type – The specific variety makes a difference. Large exhibition mums and spider mums tend to have the best staying power. Smaller pom pom types may fade faster.

-
Care – Proper conditioning, hydration, nutrients, and environment prolong vase life.
-
Water Quality – Clean, bacteria-free water keeps stems healthy.

So pay attention to flower choice, care routine, and growing conditions to maximize the vase life of your mums.

Recut stems every 2-3 days to restore water flow.

To keep bacteria from growing, change the water in your vase often. This is also good for taking care of lilies in a vase. If you want your chrysanthemums to stay healthy, don’t let water sit still. Keep giving them fresh water.
As with all flowers, Gary Wallis at Jane Packer says that a clean vase is the first thing that should be done to keep them in good shape. Clean the stems with a mild antibacterial cleaner to make sure that bacteria don’t grow in the water and hurt them. Fill the vase to approximately one third with clean water that has been pre-mixed with flower food.
We recommend changing the water every two to three days, says Valerie at 1-800-Flowers. Cut flowers will keep soaking up the water they live in because they need it to stay fresh.
Every time you change the water, use slightly warm water and cut the stems off at an angle, one to two inches from the bottom. This will give it more room to absorb water and make it more hydrated. Flower food should be replaced whenever your florals receive new water.
Each time you change the water in the vase, it’s easy to add a dash of this flower food that goes a long way.

Chrysanthemum stems will glue back together after being cut, so it’s important to cut them short before putting them in water. Trimming the stems helps to feed the bloom.
Valerie Ghitelman, Vice President of Sourcing and Design at 1-800-Flowers, says that flower stems, like chrysanthemum stems, should always be trimmed before they are arranged.
The blooms will last longer if you cut the stems at an angle. This will help them take in more water and nutrients from the flower food.
Fortunately, chrysanthemum are naturally, long lasting, flowers and this is common across all varieties, says Gary Wallis, co-founder at British and New York-based florist, Jane Packer. To ensure their longevity, cut at least 2cm/an inch from the stem at a 45 degree angle before arranging in the vase,
