Water Callicarpa acuminata regularly, especially during dry spells, to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering in winter when the plant is less active.

Prune Callicarpa acuminata in late winter or early spring before new growth begins. This encourages vigorous growth and better berry production on new wood. Remove any dead, damaged, or crossing branches.

Hard pruning can be done to control size and shape.

Propagate Callicarpa acuminata from softwood cuttings taken in late spring or semi-hardwood cuttings in mid-summer. Root the cuttings in a well-draining potting mix under humid conditions.

Alternatively, propagate from seed sown in autumn or early spring.

Repot young Callicarpa acuminata plants every 1-2 years in spring to provide fresh soil and adequate space for root growth. Mature plants generally benefit from repotting every 3-4 years.

Use a good quality, well-draining potting mix.
