Chrysanthemums were first cultivated in China. Documentation for them exists back to the 15th century B.C.; however, cultivation may be even older. The flower spread out from there, appearing in Japan in the 8th century A.D. and Europe in the 18th century A.D. Modern mums are much showier than those cultivated initially.

Mums mean many different things depending on the culture you are looking at. In China, this daisy variety is called the flower of life. It’s a fall showstopper in the USA that’s present at everything from homecoming to amazing gardens. However, in Europe, many cultures associate chrysanthemums with death.

Choosing Mums

Most people pick mums up from the garden center or their local grocery store. Choosing these established plants is an easier route than starting from seeds. Mum seeds are also an interesting route since they may not be true to the parent plant, resulting in entirely distinct colors and more.

The first step in figuring out how to care for mums is choosing a time to plant the mums. Mums have a shallow root system, but it still needs time to develop. Therefore, planting mums in the spring increases the chances they will come back year after year.

When examining plants in the garden center, you want to look for mums that have not fully bloomed yet. That means the plant has not spent its energy yet and has a better chance of rooting in a new environment. These will also provide you with blooms longer.

Pinching is essential for getting bushy mums, and without it, your mums will bloom too soon. For this procedure, you only need a set of pruning shears. You want to wait until the mum has grown to five inches and then cut off the top inch or so of growth for each stem.

Deadheading is another valuable part of how to care for mums. Performing this task helps your mums bloom longer and look neater. Deadheading involves pinching off the spent blooms at least once per week so that the plant can focus on the new buds. More buds bloom this way than would do so naturally without harming the plant.

The last part of how to care for mums is overwintering. Generally, you can overwinter any mum if you manage the soil temperature and avoid pruning them. This control requires a three- to four-inch-thick layer of mulch before the first frost. Continue to water through the winter, and the mums should come back.

Then you can compost the old centers, and you have more mums in your garden. You can also conventionally propagate mums.

    Regular watering is a crucial part of indoor mum care. Water the plant from under the leaves to help prevent fungal issues when caring for container mums.  Deadhead if you wish, to keep the plant looking its best. Keep chrysanthemum houseplants where they can receive good air circulation and avoid excess humidity . In most cases, caring for container mums is a short lived project. This is because they flower for 3 to 4 weeks and then stop. Indoor conditions are not correct to force them to re-bloom and creating the correct conditions is a pain in the neck. For this reason, most indoor gardeners simply compost the plants after they are done flowering. This may seem heartless, but mums are relatively inexpensive and very easy to find.
