Acacia mearnsii

Acacia mearnsii is a fast-growing, aggressive species that can quickly outcompete Leucadendron salignum for resources such as water and nutrients. Its extensive root system can also shade out the conebush.

Scale insects

Scale insects can infest Leucadendron salignum, sucking sap from the leaves and stems. This can cause leaf yellowing, wilting, and stunted growth. They appear as small, immobile bumps on the plant's surfaces.

Mealybugs

Mealybugs are another common pest. They also feed on plant sap and secrete a honeydew substance that can lead to sooty mold. Their presence is indicated by small, white, cottony masses on the stems and leaves.

Steps:

    • Take semi-hardwood cuttings in late spring or early summer.
    • Dip cuttings in rooting hormone.
    • Plant cuttings in a well-draining potting mix.
    • Keep the soil moist but not waterlogged.
    • Provide bright, indirect light.

Neem oil

Effective natural insecticide for controlling scale insects and mealybugs.

Kaolin clay

Acts as a physical barrier against pests, helping to prevent infestation.
