Hibiscus rosa-sinensis Firefall Double Red Sticky Leaves - Causes & Fixes

Aphid Infestation

Aphids are small, soft-bodied insects that congregate on the tender new growth and flower buds of Hibiscus, injecting piercing-sucking mouthparts into the plant to feed on sap. As they feed, they excrete a sugary substance called honeydew, which creates the characteristic sticky coating on leaves.

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf petioles of your Hibiscus, sucking nutrients from the phloem. Like aphids, they produce honeydew as a byproduct of digestion, which can coat the surrounding foliage in a sticky film.

Common

How to confirm: Look for small, immobile, bump-like protrusions on the stems that may look like bits of dirt or bark scales.

Whitefly Infestation

Whiteflies inhabit the undersides of Hibiscus leaves and feed on the plant's sap. Their excretion of honeydew results in sticky leaves, often accompanied by a fine white powder or tiny flying insects that emerge when the plant is disturbed.

Common

Mealybugs

Mealybugs are soft-bodied insects that appear as small, white, cottony masses in the crevices of Hibiscus nodes and leaf junctions. Their feeding process results in honeydew production, making the nearby foliage feel tacky.

Common
