Water
Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry.
Reduce watering slightly during winter dormancy, allowing the soil to dry out a bit more between waterings to prevent root rot.

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 during winter dormancy, allowing the soil to dry out a bit more between waterings to prevent root rot.
Prune in early spring before new growth emerges to remove dead or damaged stems and to shape the plant. Trim back any overgrown stems to maintain a desirable size and density.
Regular deadheading is not typically necessary unless seed dispersal is a concern.
Propagate from seeds sown in spring or autumn. Division of established clumps is another effective method, best carried out in early spring as new growth appears.
Ensure divisions have adequate root systems for successful transplanting.
Repot every 2-3 years, or when the plant becomes root-bound, typically in early spring. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.
Ensure the new pot has drainage holes to prevent waterlogging.
