Water regularly, especially during establishment and dry periods. Holodiscus argenteus prefers consistently moist soil but can tolerate some drought once mature. Avoid waterlogging, as this can lead to root rot.

Reduce watering in winter when the plant is dormant.

Prune after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can be done to control size.

For abundant blooms in subsequent years, avoid heavy pruning, as flowers are produced on old wood.

Propagation is typically done through seeds sown in autumn or early spring, or via semi-hardwood cuttings taken in summer. Seeds may require stratification.

Cuttings should be treated with rooting hormone and planted in a well-draining medium. Patience is key for successful propagation.

Repot young plants annually or as needed, preferably in early spring before new growth emerges. Mature plants generally do not require frequent repotting and prefer to be slightly root-bound.

Use a well-draining potting mix and a pot only slightly larger than the current root ball.
