Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment and dry periods. Allow the soil to dry slightly between waterings. In containers, ensure good drainage to prevent waterlogging.
Reduce watering in winter when the plant is dormant.
Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. To encourage flowering and maintain shape, lightly trim back overgrown stems.
Hard pruning can be done to rejuvenate older plants.
Propagate from semi-hardwood cuttings taken in summer. Select healthy shoots, remove lower leaves, and insert into a well-draining potting mix. Keep moist and in a warm, humid environment until rooted.
Can also be grown from seed, sown in spring.
Repot container-grown plants every 2-3 years, or when root-bound. Choose a pot slightly larger than the current one. Use a well-draining potting mix, such as a sandy loam. Repot in spring, just as new growth begins.
