Lilium OT Forever Sticky Leaves - Causes & Fixes

Aphid Infestation

Aphids are common pests for Liliums that pierce the plant tissue to suck sap, excreting a sugary substance known as honeydew. This residue creates a visible sticky film on the leaves and stems of the 'Forever' cultivar.

Very Common

Scale Insects

Scale insects attach themselves to the lily stems and leaves, feeding on plant fluids and secreting honeydew. Unlike aphids, these pests often look like small, stationary bumps or shells on the plant surface.

Common

Whitefly Infestation
