Anthurium andraeanum Cavalli Sticky Leaves - Causes & Fixes

Aphid Infestation

Aphids are sap-sucking insects that excrete a sugary substance called honeydew, which creates a sticky residue on the leaves of Anthuriums. They often cluster on the undersides of leaves and near new growth spikes.

Very Common

3 Inspect the undersides of leaves and new growth spikes regularly to catch any remaining pests.

Scale Insects

Scale insects attach themselves to the plant tissue and suck nutrients, secreting honeydew as a byproduct. This leads to a persistent sticky film on the foliage and can eventually cause leaf yellowing.

Very Common

How to confirm: Look for small, immobile, brown or tan bumps that can be scraped off the stems or leaf petioles with a fingernail.

Sooty Mold

This is not a direct cause of stickiness, but rather a secondary fungus that grows on the honeydew left by other pests. It appears as a black, powdery coating that can block photosynthesis in the Anthurium.

Common
