Why does your Lilium Oriental Margaux 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 Oriental lilies. They pierce the cell walls of the lily leaves to feed on the sap, leaving behind fine silk webbing as they build colonies.
Unlike spider mites, broad mites are microscopic and often cause more significant distortion in new growth. While they don't produce large webs, their presence can be associated with fine, almost invisible silk threads and stunting of the 'Margaux' flower buds.
In very high humidity, certain fungal species can produce fine mycelial networks that may resemble webbing. For Oriental lilies, this often precedes Botrytis blight, which targets the large, heavy blooms of 'Margaux'.
