Illicium arborescens prefers consistently moist soil but dislikes waterlogging. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering slightly during winter dormancy.

Ensure good drainage to prevent root rot, especially in container plantings.

Prune Illicium arborescens primarily for shape and to remove any dead, damaged, or crossing branches. Light pruning can be done after flowering.

Avoid heavy pruning, as it can disrupt the natural form and reduce flowering. Pruning is best done in late winter or early spring.

Propagation of Illicium arborescens is typically done by semi-hardwood cuttings taken in late summer or early autumn. Rooting can be slow and requires high humidity.

Alternatively, seeds can be sown, but germination is often erratic and requires stratification.

Repot Illicium arborescens every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of peat, perlite, and compost.

Repotting is best performed in early spring before new growth begins to ensure minimal stress.
