Mazus celsioides prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.

Avoid letting the soil dry out completely, especially during warmer months, but also prevent waterlogging, which can lead to root rot. Good drainage is essential.

Pruning is generally not extensive for Mazus celsioides. Deadhead spent flowers to encourage more blooms and maintain a tidy appearance.

If the plant becomes leggy or overgrown, you can trim it back in late spring or early summer to promote bushier growth. Ensure tools are clean.

Mazus celsioides can be easily propagated through division. In early spring, carefully dig up the plant and separate healthy root clumps. Replant the divisions immediately into well-draining soil.

Alternatively, stem cuttings can be taken in late spring or early summer and rooted in moist potting mix.

Repot Mazus celsioides every 2-3 years, or when the plant becomes root-bound and outgrows its container. The best time to repot is in early spring before new growth begins.

Use a well-draining potting mix and a pot that is slightly larger than the current one.
