Water Japanese Bush Cherry regularly during the growing season, especially when young or during dry spells. Ensure the soil is consistently moist but not waterlogged.

Reduce watering in late fall and winter when the plant is dormant. Check soil moisture by inserting a finger about 2-3 cm deep.

Prune Japanese Bush Cherry after flowering to maintain its shape and size, and to remove any dead, damaged, or crossing branches. Light pruning encourages bushier growth.

Avoid heavy pruning in late summer or fall, as this can stimulate new growth that may be damaged by frost.

Japanese Bush Cherry can be propagated by softwood cuttings taken in early summer, or by grafting in late winter. Seed propagation is also possible but may result in plants that do not come true to type.

Layering in spring is another effective method for this species.

Repot young Japanese Bush Cherry plants every 1-2 years in spring before new growth starts. Mature plants can be repotted less frequently, perhaps every 3-5 years. Use a well-draining potting mix.

Trim any circling or tangled roots during repotting.
