Why does your Lilium Oriental Pathos have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites are the most common cause of fine silk webbing on Oriental Lilies, particularly in warm, dry conditions. They feed on the underside of the lily leaves, causing stippling and eventually creating webs that can encompass entire flower buds or foliage.
While less common than mites, certain larvae can produce silk webbing as they move across lily foliage to create protective shelters. These pests may also leave visible feeding tracks or holes in the large, fleshy leaves of the Oriental Lily.
In extremely high humidity, certain fungal species can produce fine, thread-like mycelium that may resemble webbing. This is often accompanied by damp, darkened spots on the lily's petals or leaves.
