Fall Good Time To Plant Mums

SPRINGFIELD — Chrysanthemums (mums) are one of the most popular fall perennials for the garden because they have a glorious range of colors, a stunning display, and a longlasting show, according to Kelly McGowan, horticulture educator, University of Missouri Extension.

“There are scores of different cultivars of garden chrysanthemums from which to choose. Each year new cultivars with improved growth habits, flower color and garden performance are added,” said McGowan.

A relative newcomer has been the Belgium or European garden chrysanthemums. These cultivars are known for their spectacular size and display of color.

“Although individual flowers are smaller on these new varieties, they are borne in profusion, making for quite a show in the garden,” said McGowan.

Chrysanthemums are a member of the daisy family. They are known as short-day plants because they only bloom when the length of day reaches a critical number of hours in the fall (around 15).

There are both hardy and tender chrysanthemums. Most of the florist mums are not hardy and do not do well outdoors.

Garden chrysanthemums are available in the spring as rooted cuttings established in small containers or during the fall as large, mature plants in or near full bloom.

With most cultivars, spring-planted mums should be pinched at regular intervals every three to four weeks to promote bush, compact growth, and more flowers.

“With most cultivars, the last pinch should be made no later than mid to late July,” said McGowan.

Fall is the most popular time to plant because of the instant color. Planting soils should be well-drained and moderately fertile.
