Scale Insects

Scale insects attach themselves to the stems and leaf petioles of Gerberas, secreting sticky honeydew as they feed on plant fluids. This can lead to a heavy, waxy residue on the leaves.

Very Common

How to confirm: Look for small, immobile bumps or scale-like growths firmly attached to the plant stems.
