Terminalia catappa

Terminalia catappa can grow to be a larger tree and may shade out Hibiscus tiliaceus, impacting its ability to receive the necessary sunlight.

Hibiscus mealybug

These small, white, cottony pests suck sap from the leaves and stems, causing yellowing, stunted growth, and sooty mold. Infestations can weaken the plant.

Aphids

Small, soft-bodied insects that suck sap from leaves and stems, causing curling and yellowing. They also secrete honeydew, which can attract ants and promote sooty mold.

Scale Insects

These insects attach themselves to stems and leaves, sucking sap and causing yellowing and stunted growth. They appear as small bumps on the plant.

Steps:

    • Take stem cuttings (6-12 inches) from new growth.
    • Remove lower leaves.
    • Dip the cut end in rooting hormone (optional).
    • Plant in well-draining potting mix.
    • Keep soil moist and in indirect light.
    • Roots should form in a few weeks.
