Water Lindera aggregata regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering frequency in cooler months, but do not let the soil become completely dry, as this can stress the plant.

Pruning is generally minimal for Lindera aggregata, primarily to remove any dead, damaged, or crossing branches. Light shaping can be done after flowering to maintain its natural form.

Avoid heavy pruning, which can reduce flowering and fruiting for the season.

Propagation is best achieved through seeds, which require a period of cold stratification. Cuttings can also be taken from semi-hardwood in summer, but root development may be slow.

Sow seeds in autumn or stratify them before sowing in spring in well-draining soil.

Repot Lindera aggregata every 2-3 years, or when it becomes root-bound. The best time to repot is in early spring before new growth begins.

Use a well-draining potting mix and a pot that is only slightly larger than the current one to avoid overwatering.
