Why does your Lilium oriental Pink Expression 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 plant cells to feed on the sap, leaving behind fine silk webbing as they build colonies across the undersides of leaves and stems.
Similar to the two-spotted variety, these mites create dense webs on Lilium species when humidity levels drop. This leads to stippling (small white/yellow spots) on the 'Pink Expression' foliage before the webbing becomes prominent.
While less common as a direct cause of 'webbing,' extremely high humidity combined with stagnant air can cause certain fungal hyphae to look like fine, hair-like structures on the leaf surface.
