Water Hovenia acerba regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in winter, allowing the top few centimeters of soil to dry out between waterings.

Ensure good drainage to prevent root rot, especially for potted specimens.

Prune Hovenia acerba to shape the tree and remove any dead, diseased, or crossing branches. Light pruning can be done in late winter or early spring before new growth begins.

Heavy pruning is generally not required unless the plant is overgrown or needs structural correction.

Propagation of Hovenia acerba is typically done through seeds, which require stratification to break dormancy. Sow seeds in a well-draining seed-starting mix and keep them consistently moist and warm.

Cuttings are also possible but can be challenging to root.

Repot Hovenia acerba every 2-3 years, or when it becomes root-bound, preferably in early spring before the growing season starts. Use a well-draining potting mix and a pot that is slightly larger than the previous one.

This ensures adequate space for root development.
