How Long Do Mums Last When They Are in Bloom?

With their many colors, and various forms, mums have provided happiness for thousands of years. This is one of my favorite flowers and it’s also easy to plant them. If you are curious how long they will last, you might want to check this article.

Grown for their colorful blossoms since the 8th century in Japan, mums (Chrysanthemum morifolium) form brilliant shrub mounds when properly maintained in your garden. Preferring U.S. Department of Agriculture plant hardiness zones 5 through 9, these dense flowers can last several weeks when blooming occurs in the fall, but a number of environmental factors influence their blossoming duration.

Planting Time

For long lasting fall blooms, you need to plant your mums in the spring. Providing both spring and summer months for root establishment allows your mums to have a strong foothold in the ground for nutrient and water uptake. As a result, your flowers bloom longer and with increased numbers. Although you can purchase and plant blooming mums in the fall, they cannot bloom as long or as densely as established plants even with consistent watering patterns.

Soil and Watering

Soil preparation is a key factor influencing mum blossom longevity. Nutrient-rich compost must be tilled into the garden bed prior to planting your mums. A balanced fertilizer spread across the topsoil works well to create a healthy growing environment for the mum’s spreading roots. In fact, a monthly fertilizing regimen during the vigorous spring and summer growing season helps your plants generate many long lasting blooms in the fall. Daily watering coupled with the amended soil also promotes healthy roots so that blossoms may last longer with ample moisture. However, you need to keep an eye on the soil’s moisture levels — soggy conditions tempt root rot that stifles all growth.
