Why does your Lilium OT Carbonero have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are small, soft-bodied insects that pierce the lily's cell walls to suck sap, excreting a sugary substance known as 'honeydew' which makes leaves sticky.
Scale insects attach themselves to the stems and leaves of Lilium species; they also excrete honeydew that creates a persistent sticky film on the foliage.
Adult whiteflies reside on the undersides of the leaves and feed on plant fluids, leaving behind sticky honeydew residue as they multiply.
These pests produce honeydew and are often accompanied by a white, cottony waxy coating on the lily's nodes or leaf bases.
