Purple Moorgrass prefers consistently moist soil but can tolerate some dryness once established. Water regularly during the growing season, especially in hot, dry weather.

Allow the top few centimeters of soil to dry out slightly between waterings to prevent waterlogging. Reduce watering in autumn and winter.

Cut back Purple Moorgrass to about 10-15 cm above the ground in late winter or early spring before new growth emerges. This removes dead foliage and encourages vigorous new shoots.

Remove any dead or damaged leaves throughout the growing season to maintain a tidy appearance. Deadheading is not typically required.

Purple Moorgrass is primarily propagated by division. In spring or autumn, carefully dig up the plant and divide the root ball into sections using a sharp spade or knife.

Ensure each division has healthy roots and shoots. Replant divisions immediately into well-prepared soil at the same depth as the parent plant.

Repotting is generally only necessary for container-grown plants when they become root-bound, typically every 2-3 years. Choose a pot that is only slightly larger than the current one.

Repot in spring as new growth begins. Ensure good drainage in the new pot. Water thoroughly after repotting.
