Fall is possibly the most popular time to plant because of the instant color. Soils should be well-drained and moderately fertile. Both spring and fall are suitable for planting mums.
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 compact growth and more flowers. Generally, the last pinch should be made no later than mid- to late July.
