Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering in cooler months. Ensure good drainage to prevent root rot.
Overwatering is a common issue; monitor soil moisture carefully.
Prune to maintain shape, remove dead or damaged branches, and encourage bushier growth. Light pruning can be done at any time, but heavier pruning is best done in late winter or early spring before new growth begins.
Remove suckers from the base.
Easily propagated from seeds sown in spring or summer. Germination can be improved by scarifying the seeds or soaking them in warm water overnight. Cuttings can also be taken from semi-hardwood in summer.
Young plants benefit from repotting annually in spring. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix. Ensure the new pot is only slightly larger than the previous one.
