Spider Mites

Spider mites are tiny pests that suck sap from the leaves, causing stippling, yellowing, and eventual leaf drop. They thrive in dry conditions. Fine webbing may be visible on the plant.

Scale

Scale insects are sap-sucking pests that appear as small bumps on the stems and leaves. They can weaken the plant and cause yellowing or distorted growth. They secrete a sticky substance called honeydew, which can attract sooty mold.

Aphids

Aphids are small, soft-bodied insects that feed on plant sap, causing distorted growth, yellowing, and honeydew production. They are often found on new growth.

Steps:

    • Take semi-hardwood cuttings from healthy, disease-free Wollemi Pine trees in late winter or early spring.
    • Cuttings should be 10-15 cm long and have several nodes.
    • Remove the lower leaves, leaving a few at the top.
    • Dip the cut end in rooting hormone to encourage root development.
    • Plant the cuttings in a well-draining potting mix of perlite and peat moss.
    • Keep the cuttings moist and in a humid environment, such as a propagation chamber or under a plastic bag.
    • Roots should develop in several weeks, at which point the cuttings can be transplanted into individual pots.
