Water moderately during the growing season, especially when young. Allow the soil to dry slightly between waterings. Reduce watering in autumn and keep the soil barely moist during winter dormancy.

Ensure good drainage to prevent waterlogging, which can lead to root rot.

Prune after flowering to maintain shape and size. Remove any dead, damaged, or crossing branches. Light pruning can be done to encourage bushier growth.

Avoid heavy pruning, as it can reduce flowering in the following year. Clean cuts encourage faster healing.

Best propagated from seeds sown in autumn or early spring. Seeds may require stratification. Grafting onto Laburnum anagyroides rootstock is also a successful method.

Softwood cuttings can be taken in early summer but are often difficult to root.

Young plants may require repotting every 2-3 years in spring before new growth begins. Mature plants generally do not need frequent repotting and prefer to be slightly pot-bound. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the old one.
