Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged, especially during the growing season. Water thoroughly when the top inch of soil feels dry.
Reduce watering slightly in winter when growth slows, but avoid letting the plant dry out completely.
Prune back stems in late winter or early spring to encourage bushier growth and prevent legginess. Deadhead spent flowers to promote reblooming and maintain a tidy appearance.
Pruning also helps manage the plant's size and shape.
Propagate by division of clumps in early spring or by taking stem cuttings in late spring or early summer. Cuttings should be placed in moist potting mix and kept in a warm, humid environment until roots form.
Repot every 2-3 years in spring when the plant becomes root-bound or outgrows its container. Use a well-draining potting mix. Choose a pot that is slightly larger than the current one to accommodate new growth.
