Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment and dry periods. Allow the top few centimeters of soil to dry out between waterings.
Dianella caerulea is relatively drought-tolerant once established, but consistent moisture promotes best growth and flowering. Reduce watering in winter.
Pruning is generally minimal, primarily involving the removal of old or dead flower stalks and any yellowing or damaged foliage. Cut back spent flower spikes after flowering to maintain a tidy appearance.
This encourages further blooming and keeps the plant healthy.
Propagation is typically done by division of established clumps in spring. Carefully separate the rhizomes with a sharp spade or knife, ensuring each section has roots and shoots.
Alternatively, seeds can be sown in spring, but germination may be slow and erratic.
Repotting is usually only necessary for container-grown plants, or when dividing established clumps. Dianella caerulea prefers to be slightly root-bound.
If the plant outgrows its pot, choose one only slightly larger and repot in spring, using a well-draining potting mix.
