Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in autumn and winter. Ensure good drainage to prevent root rot, especially in containers.

Overwatering is the most common cause of problems.

Deadhead spent flower spikes to encourage reblooming and maintain a tidy appearance. In late autumn or early spring, cut back the dead foliage to the ground.

This helps prevent disease and allows new growth to emerge unhindered.

Liatris aestivalis can be propagated by division of clumps in early spring or autumn. Seeds can also be sown in autumn or after a period of cold stratification.

Divisions should be replanted promptly, ensuring the crown is at or slightly below the soil surface.

Container-grown plants typically benefit from repotting every 2-3 years. Repot in early spring before new growth begins.

Choose a pot that is only slightly larger than the current one to avoid excess soil that retains too much moisture. Use a well-draining potting mix.
