Water Kelway's Coral Plume regularly during the growing season, keeping the soil consistently moist but not waterlogged.

Reduce watering in autumn and winter, allowing the top few centimeters of soil to dry out between waterings. Ensure good drainage to prevent root rot.

Prune Macleaya microcarpa in late winter or early spring before new growth begins. Cut back old stems to near ground level to encourage vigorous new shoots.

Remove any dead or damaged foliage at any time of year to maintain plant health and appearance.

Propagate Macleaya microcarpa by division in early spring. Carefully lift established clumps and divide them into smaller sections, ensuring each piece has roots and shoots.

Replant divisions immediately into well-draining soil. Stem cuttings can also be taken in late spring.

Repot Kelway's Coral Plume every 2-3 years in early spring as needed. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

This plant can become quite large, so consider the mature size when selecting a pot.
