Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, especially when young or in containers, to keep the soil consistently moist but not waterlogged. Reduce watering in fall and winter, allowing the soil to dry slightly between waterings to prevent root rot.
Cut back all dead foliage to about 10-15 cm from the ground in late winter or early spring, before new growth emerges. This tidies the plant and encourages vigorous new shoots.
Remove any damaged or diseased stems as needed throughout the year.
Propagate by division in early spring as new growth begins. Carefully dig up the plant and divide the root ball into sections, ensuring each section has roots and at least one viable bud.
Replant divisions immediately at the same depth.
Repot container-grown plants every 2-3 years in spring before new growth starts. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.
Ensure adequate drainage holes to prevent waterlogging.
