Hibiscus moscheutos Sticky Leaves - Causes & Fixes

error

Aphid Infestation

Aphids are small, soft-bodied insects that pierce the tender stems and leaves of Hibiscus moscheutos to suck sap, excreting a sugary substance known as honeydew. This residue creates the characteristic sticky coating on leaf surfaces.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf petioles of the Rose Mallow, feeding on phloem sap. Like aphids, they excrete honeydew which accumulates on the foliage below them.

Very Common

How to confirm: Look for small, stationary, scale-like bumps on the stems that can be scraped off with a fingernail.

Whitefly Infestation

Whiteflies congregate on the undersides of Hibiscus leaves to feed; their waste products result in a sticky film. A cloud of tiny white insects may emerge when the plant is disturbed.

Common

Sooty Mold (Secondary Infection)

While not the cause of the stickiness, sooty mold is a black fungus that grows specifically on the honeydew left by sucking insects. It can eventually coat the large leaves of your Hibiscus in a dark, velvety layer.

Common
