Tea Tree Beetle

The Tea Tree Beetle (Paropsisterna selmani) can defoliate Leptospermum petersonii. Symptoms include chewed leaves, stunted growth and potentially plant death if infestation is severe.

Scale Insects

Scale insects suck sap from the plant, weakening it. Look for small, raised bumps on stems and leaves. Heavy infestations can cause leaf drop and stunted growth.

Steps:

    • Take semi-hardwood cuttings from healthy, disease-free plants in late spring or early summer.
    • Cuttings should be approximately 10-15 cm long.
    • Remove the lower leaves, leaving only a few leaves at the top.
    • Dip the cut end in rooting hormone.
    • Plant the cuttings in a well-draining propagation mix (e.g., perlite and vermiculite).
    • Keep the mix moist but not waterlogged.
    • Place the cuttings in a propagator or cover with a plastic bag to maintain humidity.
    • Provide indirect light.
    • After several weeks, check for root development by gently tugging on the cuttings.
    • Once rooted, gradually acclimatize the new plants to outdoor conditions before transplanting into larger pots or the garden.
