Overwintering Garden Mums: Cutting Back, Mulching, and Propagation

Keeping Fall Mums Alive: Winter Protection and Propagation Techniques

Garden mums (Chrysanthemum morifolium) are perennials in most zones, but survival depends on hardiness type and winter care. Hardy mums return reliably with proper preparation.

Winter Preparation

• Mid-November: Cut back by one-third
• Cover with shredded leaves (contain with mesh/chicken wire)
• Spring: Remove leaf mulch; plants emerge and bloom again in fall

Propagation: Cuttings Over Seeds

Most garden mums are hybrids—seeds won't come true. Cuttings preserve exact color and habit:

1. Cut tender shoot, remove all but top leaf set
2. Dip in rooting hormone
3. Plant in 4-inch pot with quality potting mix
4. Water deeply, cover with clear plastic for humidity
5. Check rooting in 2 weeks (gentle tug test)
6. Remove plastic, grow as seedling

Tender vs. Hardy Mums

In northern zones, tender (florist) mums won't survive winter regardless of care. Purchase hardy garden mums for perennial performance.
