Weeping Figs require more frequent watering than Hoya kerrii, potentially leading to overwatering issues for the Hoya.

Mealybugs

Mealybugs are small, white, cottony insects that suck sap from plants. They can be found in the crevices of leaves and stems. Infestation symptoms include stunted growth and honeydew secretions, which can lead to sooty mold.

Aphids

Aphids are small, soft-bodied insects that feed on plant sap. They can cause distorted leaves and stunted growth. They also secrete honeydew.

Spider Mites

Spider mites are tiny pests that create webs on plants and feed on the leaves. Symptoms include stippled leaves and overall weakness of the plant.

Steps:

    • Take a stem cutting with at least two leaves from a healthy Hoya kerrii vine.
    • Allow the cut end to callous over for a few days to prevent rot.
    • Dip the cut end in rooting hormone (optional but recommended).
    • Plant the cutting in well-draining potting mix or perlite.
    • Keep the potting mix consistently moist but not waterlogged.
    • Provide warmth and bright, indirect light.
    • Roots should develop in a few weeks to months.
