Aralia cordata prefers consistent moisture. Water regularly, especially during dry periods, ensuring the soil remains evenly moist but not waterlogged. Reduce watering in winter when the plant is dormant.

Good drainage is crucial to prevent root rot.

Prune Aralia cordata in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing stems. You can also cut back the plant hard to encourage bushier growth or to manage its size.

New shoots can be harvested for culinary use.

Propagate Udo from seeds sown in autumn or spring, or by division of established clumps in early spring. Stem cuttings can also be taken in early summer. Seeds may require stratification.

Divisions should be replanted promptly into moist, well-prepared soil.

Young plants may need repotting every 1-2 years, while mature plants are best left undisturbed. Repot in spring if the plant becomes root-bound or outgrows its container.

Use a well-draining potting mix and a pot only slightly larger than the current one.
