Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged during the growing season. Reduce watering in winter, allowing the top few centimeters of soil to dry out between waterings. Ensure good drainage to prevent root rot.
Prune to maintain shape and encourage bushier growth. Pinch back the tips of new stems in spring and summer. Remove any dead or leggy stems at any time to improve air circulation and appearance.
Easily propagated from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep moist and in a warm location with bright, indirect light.
Repot every 2-3 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
