Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.
Reduce watering in cooler months when the plant's growth slows down to prevent root rot.
Prune to maintain desired shape and size, and to encourage bushier growth. Remove spent flower stalks to prevent self-seeding and prolong blooming.
Light pruning can be done anytime, with heavier pruning best done in late winter or early spring before new growth begins.
Easily propagated from stem cuttings taken in spring or summer. Dip cuttings in rooting hormone and plant in moist, well-draining potting mix.
Keep in a warm, humid environment with bright, indirect light until roots develop.
Repot young plants annually in spring to provide fresh soil and more space. Mature plants can be repotted every 2-3 years. Choose a pot one size larger with drainage holes. Use a well-draining potting mix.
