How to Propagate Chrysanthemum

Chrysanthemum × morifolium · Also called Mum

Garden mums divide easily in spring and also root well from stem cuttings taken from new growth. Divide every spring for the healthiest, most floriferous plants — this species benefits from regular rejuvenation.

Division

Dig up the clump in spring, separate sections with roots and shoots, replant.

Stem cutting

Take 3-inch cuttings from new spring growth, root in moist, well-draining mix.

When to propagate

Spring.

Common problems

Cutting wilted. Cover loosely for humidity during the first couple of weeks.

Questions people ask

Are grocery store “mums” the same as garden mums? Often not — many sold as seasonal decor are less cold-hardy varieties bred for short-term display rather than perennial garden use; check before assuming winter survival.

Is it toxic? Mildly — it can cause GI upset if eaten by pets, and the sap occasionally irritates skin in sensitive people during heavy handling. Nothing to worry about for normal propagation.
