Why does your Lilium oriental Vasari 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 individual plant cells to feed on the sap, resulting in characteristic fine silk webbing across the undersides of leaves and stem junctions.
These mites create much finer, less visible webbing than two-spotted varieties but cause similar stippling on the lily foliage. They are particularly common in greenhouse settings or during periods of low humidity.
While not a primary cause of webbing, extremely high humidity combined with poor airflow around dense Lilium foliage can lead to fungal hyphae appearing as fine, thread-like structures. This is often mistaken for mite webs but lacks the structural silk density.
