Water yellow ʻilima moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in cooler months, but avoid complete dryness.

Ensure good drainage to prevent root rot, especially for potted specimens. Overwatering is a common pitfall.

Prune yellow ʻilima lightly after flowering to shape the plant and encourage bushier growth. Remove any dead or crossing branches. Major pruning can be done in late winter or early spring before new growth begins.

This helps maintain a tidy appearance.

Yellow ʻilima is typically propagated from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep moist and warm for best results.

Seeds can also be used but may be slower.

Repot yellow ʻilima every 2-3 years, or when it becomes root-bound. Choose a pot only slightly larger than the previous one, with excellent drainage holes. Use a well-draining potting mix.

Repot in spring before the active growing season commences.
