Why does your Lilium Forfour have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These tiny arachnids thrive in hot, dry conditions and feed on the underside of Lily leaves, injecting toxins that cause stippling and produce characteristic fine silk webbing. High humidity and cooler temperatures can help suppress their rapid reproduction cycles.
Similar to the two-spotted variety, these mites create fine webs that can eventually cover entire Lily foliage, leading to chlorosis and premature leaf drop. They are particularly aggressive when Lily plants experience drought stress.
While not a direct cause of webbing, Edema causes cells to burst due to excessive water uptake, creating bumps that can sometimes trap dust and debris, mimicking a messy appearance. This is often accompanied by the mite infestations mentioned above because both thrive in high moisture/high heat transitions.
