Why does your Chrysanthemum Summer Surprise Holiday 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 holiday mums. They pierce the leaf cells to feed, resulting in characteristic fine silken webbing across the foliage and undersides of leaves.
Common in indoor holiday mum displays, these mites create fine webbing and cause yellowing or stippling on the chrysanthemum leaves. They are particularly aggressive when humidity levels drop significantly.
While not true webbing, extremely high humidity combined with poor air circulation can cause fungal hyphae to look like fine, misty threads on dense chrysanthemum blooms.
