Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water moderately, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. In hotter climates, increase frequency.
Reduce watering in cooler months to prevent waterlogged soil and potential fungal issues.
Prune to maintain shape and size, and to remove dead or diseased branches. Light pruning can be done anytime, but heavier pruning is best after flowering.
This encourages bushier growth and can improve air circulation within the plant structure.
Propagate from semi-hardwood cuttings taken in late spring or early summer. Use a rooting hormone to improve success rates.
Plant cuttings in a well-draining potting mix and keep them consistently moist and warm until roots develop.
Repot every 2-3 years or when the plant becomes root-bound, preferably in spring. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the current one to avoid excessive soil moisture retention.
