Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in winter, providing just enough to prevent the soil from becoming completely dry.

Ensure good drainage to avoid waterlogging, which can lead to root rot.

Prune Dianella revoluta to remove dead, damaged, or diseased foliage. Trim back overgrown or leggy stems to maintain a tidy shape.

Pruning can be done anytime the plant looks untidy, but is best done after flowering to avoid removing potential flower stalks.

Propagate Dianella revoluta by dividing established clumps in spring or autumn. Carefully separate the rhizomes, ensuring each division has roots and shoots. Replant divisions immediately into well-draining soil.

Seeds can also be sown, but germination can be slow and erratic.

Repot Dianella revoluta when it becomes root-bound, typically every 2-3 years. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in spring before new growth begins.
