Water
Keep the soil consistently moist but not waterlogged. Water when the top centimeter of soil feels dry. Reduce watering slightly during winter dormancy, but never allow the soil to dry out completely.
Overwatering can lead to root rot.

Keep the soil consistently moist but not waterlogged. Water when the top centimeter of soil feels dry. Reduce watering slightly during winter dormancy, but never allow the soil to dry out completely.
Overwatering can lead to root rot.
Pruning is generally not required beyond removing any dead or damaged foliage. If the plant becomes overgrown or you wish to shape it, trim back stems after flowering. Use clean, sharp tools to make precise cuts.
Propagate by division in early spring or fall. Carefully dig up the plant and divide the rhizomes, ensuring each section has roots and at least one growth bud. Replant divisions immediately in well-draining soil.
Repot young plants annually in spring, and mature plants every 2-3 years. Use a well-draining potting mix, such as a blend of peat, compost, and perlite. Choose a pot that is slightly larger than the current one.
