Why does your Lilium Hybrid Triumphator have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often experienced by Triumphator lilies during summer. They pierce cell walls to feed on sap, creating characteristic fine silken webs that cover the undersides of leaves and stems.
While less common than the two-spotted variety, certain mite species create much denser, more structural webbing across the lily foliage when humidity levels drop significantly.
While thrips do not spin webs, heavy feeding damage can cause silvering and scarring that, when combined with frass (excrement), may appear as a messy, fine residue or silken texture on the lily petals and leaves.
