Water Viburnum rugosum regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Aim to water deeply to encourage strong root development.

Reduce watering in winter when the plant is dormant. Check the soil moisture before watering to avoid over-saturation, which can lead to root rot.

Prune Viburnum rugosum after flowering to maintain its shape and size, and to remove any dead, damaged, or crossing branches. Light pruning can be done at any time to improve air circulation.

Avoid heavy pruning in late summer or fall, as this can remove potential flower buds for the following season.

Propagate Viburnum rugosum from semi-hardwood cuttings taken in mid-summer. Dip the cuttings in rooting hormone and plant them in a well-draining potting mix.

Keep the cuttings moist and in a humid environment, such as a propagator or under a plastic bag. Rooting typically occurs within 6-8 weeks.

Repot young Viburnum rugosum plants every 2-3 years, or when they become root-bound. Use a slightly larger pot with fresh, well-draining potting soil. Repotting is best done in early spring before new growth begins.

Water thoroughly after repotting to help settle the soil and reduce transplant shock.
