Keep the soil consistently moist but not waterlogged, especially during dry spells. Water deeply at the base of the plant, avoiding overhead sprinkling which can encourage fungal diseases.

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

Prune immediately after flowering to shape the plant and remove any dead, damaged, or crossing branches. Avoid heavy pruning in late summer or autumn, as this can remove flower buds for the next season.

Aim for a balanced, open structure to improve air circulation.

Best propagated by seed sown in autumn or by semi-hardwood cuttings taken in mid-summer. Seeds require stratification.

Cuttings should be treated with rooting hormone and placed in a moist, well-draining medium in a propagator or humid environment.

Repot container-grown Rhododendron luteum every 2-3 years, or when the plant becomes root-bound. Use a well-draining, ericaceous compost. Ensure the new pot is only slightly larger than the old one.

Water thoroughly after repotting.
