Why does your Chrysanthemum Pico Mundo have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
These microscopic arachnids thrive in the warm, dry conditions often experienced by Chrysanthemum Pico Mundo. They pierce plant cells to feed on sap, creating characteristic fine silk webbing across the leaf undersides and stems.
A specific strain of spider mite that is highly prevalent in greenhouse-grown mums. The webbing is often accompanied by 'stippling,' which are tiny yellow or white dots on the foliage where the mites have fed.
While not a pathogen, extremely dry air can cause the plant's fine hairs (trichomes) to trap dust and debris, which may visually mimic light webbing. This stress often makes the plant more susceptible to subsequent mite attacks.
