Why does your Lilium hybride Palm Place have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These microscopic arachnids thrive in the warm, dry conditions often experienced by Oriental lilies. They pierce plant cells to feed on sap, leaving behind fine silk webbing as they create colonies on the undersides of leaves.
In high humidity or late-stage infestations, spider mites produce denser webbing to protect eggs. This can make the lily foliage appear dusty or coated in a fine mesh.
While thrips primarily cause silvering or scarring on lily petals and leaves, their movement and feeding can sometimes result in a slight silken appearance or debris that mimics fine webbing.
