Watering, pruning, propagation, and repotting details from plant data
Water regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogging, which can lead to root rot. Reduce watering in cooler months when growth slows.
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. Can be pruned to encourage denser growth.
Easily propagated from semi-hardwood cuttings taken in summer. Root cuttings in a well-draining potting mix, kept moist and warm. Can also be grown from seed, though germination can be slow and erratic.
Repot young plants every 1-2 years in spring, and mature plants as needed, typically every 3-5 years. Use a well-draining potting mix. Ensure the new pot is only slightly larger than the previous one.
