Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly in cooler months to prevent root rot.
Ensure good drainage to avoid standing water, especially during dormant periods.
Prune to maintain shape and size, or to remove dead or damaged stems. Cut stems back to just above a node. Pruning can also encourage bushier growth. It's best done in spring before new growth begins.
Easily propagated from stem cuttings or by dividing rhizomes. For stem cuttings, take 10-15 cm pieces and root them in moist potting mix or water.
Rhizome division should be done when repotting, ensuring each piece has at least one growth bud.
Repot every 1-2 years 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. Repot in spring before the active growing season commences.
