Mums are planted in the fall or in the early spring, and those planted in the spring are generally fuller than those planted in the fall. They should not be crowded. To keep them from becoming leggy, mums should be pinched back no more than an inch every month or so, but not pruned in the fall. If the plants are being raised as perennials, they should be divided after three years.
Mums also need to be well-watered. They especially need water when they're in bloom. Mulching around the plant is also recommended to hold in water and suppress weeds. Blooming is supported by fertilizer. The plant should be fed every week.
Chrysanthemums are stimulated to bloom by the shorter days and longer nights that arrive with the fall. Therefore, they shouldn't be placed around artificial light sources at night.
Different chrysanthemum cultivars have different kinds of petals. They can be singles or daisies, anemones, decoratives, pompoms or cushions.Learn more about Outdoor Plants & Flowers
