Arctic AsterEurybia sibirica

Water Siberian Aster regularly, keeping the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings, especially during hot, dry periods.

Reduce watering in autumn as the plant enters dormancy.

Prune Siberian Aster after flowering to tidy up the plant and prevent self-seeding if undesired. Deadhead spent blooms regularly to encourage further flowering.

Cut back the stems to the ground in late autumn or early spring before new growth begins.

Propagate Siberian Aster by division in early spring or autumn. Carefully dig up established clumps and separate them into smaller sections, ensuring each section has roots and shoots.

Replant immediately into well-prepared soil. Seed propagation is also possible but may result in less predictable blooms.

Repot Siberian Aster every 2-3 years, or when the plant appears overcrowded and growth slows. This is best done in early spring before new growth starts.

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