Keep the soil consistently moist, especially during establishment and dry periods. Cephalanthus salicifolius thrives in damp conditions, so regular watering is crucial.

Avoid prolonged waterlogging, but do not allow the soil to dry out completely. Check soil moisture by feeling the top few centimeters.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain a desirable shape and encourage robust flowering.

Light pruning can also be done after flowering to deadhead spent blooms and promote a tidier appearance.

Propagate from semi-hardwood cuttings taken in summer or from seed sown in autumn. Cuttings should be rooted in a well-draining, moist medium.

Seeds require stratification, so sow them outdoors in a cold frame or in the refrigerator over winter for best germination.

Repot young plants annually in spring, moving them to a slightly larger container. Mature plants are less frequent repotters and can be left in their pots for several years.

Ensure the new pot has adequate drainage holes to prevent root rot. Use a well-draining potting mix.
