Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry spells, allowing the soil to dry out slightly between waterings. Avoid overwatering, which can lead to root rot. In containers, ensure good drainage.
Reduce watering in winter when the plant is dormant.
Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and improve air circulation. Light pruning can encourage bushier growth.
Avoid heavy pruning, which can stress the plant.
Propagate from seed sown in autumn or spring. Semi-hardwood cuttings can also be taken in summer and rooted in well-draining potting mix. Seed germination can be slow and requires patience.
Rooted cuttings will establish faster.
Repot young plants annually or every two years in spring. Mature plants may only need repotting every 3-4 years. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the current one to avoid waterlogged soil.
