Why does your Anthurium andraeanum Arion 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 Anthuriums. They feed on the underside of the leaves, injecting saliva that damages cells and results in the characteristic fine silk webbing.
While they do not produce large webs like spider mites, broad mites can cause leaf distortion and secondary silk production from other pests. They are microscopic and often found in the tight crevices of Anthurium spadix or new leaf growth.
Anthurium 'Arion' requires high humidity; when the environment is too dry, the plant's natural defenses weaken, making it much more susceptible to mite outbreaks which produce webbing.
