Mazus caducifer prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

In hotter or drier conditions, more frequent watering may be necessary to maintain optimal moisture levels for this groundcover.

Prune after flowering to maintain a neat appearance and prevent excessive spreading. Deadhead spent blooms to encourage further flowering. In late autumn, consider a light trim to tidy up the plant before winter.

This helps manage its vigorous groundcover habit.

Mazus caducifer is easily propagated by division in early spring or autumn. Carefully dig up clumps and separate them into smaller sections, each with roots and shoots.

Replant divisions immediately into prepared soil, ensuring they are well-watered to establish.

Repotting is generally not required for Mazus caducifer as it is a groundcover often planted directly in the ground. If grown in containers, repot every 2-3 years in spring into a slightly larger pot with fresh, well-draining potting mix to refresh the soil and accommodate root growth.
