Why does your Zantedeschia Captain Palermo 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 Calla Lilies, creating fine silk webs to protect themselves and their eggs on the underside of leaves. They pierce cell walls to feed, which can lead to stippling and chlorosis on the large foliage of 'Captain Palermo'.
This specific mite species is highly aggressive in indoor environments with low humidity, producing dense webbing that can eventually envelop entire flower spathes. High populations will cause the distinctive deep green leaves of this cultivar to turn dull and mottled.
While less common, certain fungal pathogens in extremely stagnant, high-humidity environments can produce fine, thread-like mycelium that may be mistaken for insect webbing. This is usually accompanied by soft, decaying spots on the rhizome or leaf base.
