The Best Time to Plant Chrysanthemums

Ideal Planting Time

• Ideally chrysanthemums of all kinds should be planted in the spring if you want them as part of the landscaping. You may want to plant garden mums as annuals and hardy mums as perennials, but in many places either type can winter over if they have had enough time to develop strong roots.

Availability

• Frequently, hardy chrysanthemums are only available from late summer into fall since this is when they are at their most spectacular. Purchase these mums as early as possible to give them the best chance at survival. If you intend to grow chrysanthemums in pots, however, you can safely wait to plant them as long as you have a place to bring them in from the cold.

Planting From Cuttings

• Divide chrysanthemums in the spring of their second year to keep them vigorous. Dig up chrysanthemum clumps once shoots have appeared. Using a sharp trowel or knife, carefully cut away the new plants that have formed along the outside of the clump, being sure to leave roots for each section. Replant the old clump as well as the cuttings as quickly as possible to avoid drying them out.

After Planting Care

• Chrysanthemums are thirsty, heavy feeders. Plant them in a sunny, well-drained location and water well each day. Apply mulch to help maintain a evenly moist soil, and don't skimp on fertilizer. Mums that are reestablishing their roots need weekly fertilization. When the plant begins to grow vigorously, pinch back the tips of the shoots to help them keep their shape.
