Hibiscus rosa sinensis Firefall Orange Sticky Leaves - Causes & Fixes

error

Aphid Infestation

Aphids are small, soft-bodied insects that pierce the tender new growth of Hibiscus to suck sap, excreting a sugary substance called honeydew. This residue creates a visible sticky film on the leaf surfaces.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf petioles of the Chinese Hibiscus, feeding on phloem sap. Like aphids, they excrete honeydew which coats the leaves in a sticky layer.

Very Common

Whitefly Infestation

Whiteflies congregate on the undersides of Hibiscus leaves, sucking nutrients and leaving behind sticky honeydew. This often results in a shiny, tacky coating on the top of the foliage.

Common

warning

Sooty Mold Development

While not the primary cause, sooty mold is a black fungus that grows specifically on the honeydew left by other pests. This makes the leaves feel extremely sticky and appear covered in dark soot.

Common
