Sticky leaves on indoor plants are often a sign of pest infestation, as they are often caused by scale insects. These tiny insects secrete a sticky residue called honeydew, which is a sugary substance that is produced by insects that suck sap from plant leaves and stems. This excretion often coats lower leaves, tables, and other surfaces.
Insects such as mealybugs, aphids, and scale are the most common culprits for sticky leaves on plants. They feed on plant juices and secrete the excess as honeydew. When aphids, mites, whitefly, mealybugs, or scale are feeding on your plant, they suck the plant juices and secrete the excess as honeydew. If you notice any stickiness in your plants, it may be due to honeydew from aphids or scale.
To identify the cause of sticky leaves on plants, check under all leaves and around any crevices. If your plants appear shiny, wet, and sticky, it is likely that they have an infestation of scales, tiny insects that latch onto your plant and suck out its moisture. Honeydew is a clear, sugary substance produced by insects that suck sap from plant leaves and stems, often coating lower leaves, tables, and other surfaces.
In addition to the sticky residue, the cause of sticky leaves can also be caused by dried salts/minerals from the soil, liquid fertilizer, and/or water. By examining the underside of leaves and around any crevices, you can help identify the root causes of the problem and take steps to address it.
