Water regularly, especially during establishment and dry periods, but avoid waterlogging. Allow the top few centimeters of soil to dry out between waterings. Reduce watering in winter when the plant is dormant.

Consistent moisture is key for optimal flowering and health.

Deadhead spent flower spikes to encourage further blooming and maintain a tidy appearance. Cut back the foliage to the ground in late autumn or early spring before new growth emerges.

This removes old leaves and debris, preventing potential disease issues.

Bistorta affinis is easily propagated by division in early spring or autumn. Lift the clumps and carefully divide them into smaller sections, ensuring each piece has roots and shoots.

Replant immediately at the same depth as before. Seeds can also be sown in autumn.

Established plants generally do not require frequent repotting and prefer to be slightly pot-bound. If repotting is necessary, typically every 2-3 years, do so in early spring.

Choose a pot only slightly larger than the current one, using well-draining soil.
