Why does your Zantedeschia Captain Brunello have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the warm, dry conditions often found around Calla Lilies, creating fine silken webs to protect themselves and their eggs. These tiny arachnids pierce the plant cells to feed on the sap, leading to stippling and eventual foliage decline.
In warmer climates, this specific mite species can cause similar webbing patterns on Zantedeschia foliage. They are particularly aggressive when humidity levels drop significantly, which is often the case in indoor environments.
While not a direct cause of webbing, extremely dry air can cause the leaf edges to desiccate and fray, which may trap dust and debris that resembles fine web-like structures. This is common when Zantedeschia are kept near heating vents.
