Scale insects

Scale insects can infest Lomandra, sucking sap and causing yellowing or browning of leaves. They appear as small, hard bumps on the stems and leaves. Infestations can weaken the plant.

Mealybugs

Mealybugs are small, soft-bodied insects that feed on plant sap. They leave behind a white, cottony residue. Heavy infestations can stress the plant and lead to leaf drop.

Steps:

    • Carefully dig up a mature Lomandra clump.
    • Separate the clump into smaller sections, ensuring each section has healthy roots and foliage.
    • Replant the divisions in well-drained soil.
    • Water well after planting.
