Why does your Lilium LA Hybrid Tonka 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 LA Hybrids. They pierce the lily cells to feed, leaving behind fine silk webbing as they build colonies on the undersides of leaves and around flower buds.
This specific mite species is highly prevalent in greenhouse-grown lilies. The fine webbing is a structural byproduct of their lifecycle, often accompanied by stippling (tiny white dots) on the lily foliage.
While rare to present as 'webbing,' certain fungal hyphae can appear thread-like across leaf surfaces in extremely stagnant, humid environments. This is less common than mite damage but can mimic fine silk.
