Keep the soil consistently moist but not waterlogged. Water thoroughly when the top centimeter of soil feels dry.

Avoid letting the plant dry out completely, especially during warmer months, but ensure good drainage to prevent root rot. Reduce watering in winter.

Prune Tiarella polyphylla after flowering to maintain shape and remove spent flower stalks. Deadhead faded blooms to encourage reblooming or to prevent unwanted self-seeding.

Lightly trim any unruly stems to keep the plant tidy. No heavy pruning is usually required.

Propagate by division in early spring or fall. Carefully dig up the plant and separate clumps of rooted rhizomes. Replant divisions immediately into prepared soil.

You can also propagate from basal cuttings taken in late spring, rooting them in moist, well-draining medium.

Repot Tiarella polyphylla every 2-3 years, or when the plant becomes root-bound. Spring is the ideal time. Use a well-draining potting mix amended with organic matter.

Choose a pot that is slightly larger than the current one. Ensure good drainage holes.
