Ilex collina prefers consistently moist soil, especially during its establishment period. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering in winter when growth slows, but do not allow the soil to dry out completely.

Prune Ilex collina to maintain its shape and remove any dead, damaged, or crossing branches. The best time for structural pruning is in late winter or early spring before new growth begins.

Light shaping can be done after flowering to encourage bushier growth, but avoid heavy pruning.

Propagation is typically achieved through semi-hardwood cuttings taken in summer. Select healthy shoots, remove lower leaves, and dip the cut end in rooting hormone.

Plant in a well-draining potting mix and keep moist in a warm, humid environment until roots form.

Repot Ilex collina only when it becomes root-bound, typically every 2-3 years for younger plants. Use a well-draining potting mix and a pot that is slightly larger than the current one.

Repot in early spring before the onset of active growth for best results.
