Why does your Anthurium andraeanum Maine have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The presence of fine webbing is a classic hallmark of spider mite infestations, which thrive in the low-humidity environments often found with Anthuriums. These microscopic arachnids pierce plant cells to suck out sap, leading to stippling and eventual leaf drop.
If the webbing is dense and covering large areas of the foliage, it indicates a mature colony. In Anthuriums, this often results in the characteristic yellowing or bronzing of the leaves alongside the silk structures.
While less common than mites, certain fungal pathogens can create a fine, thread-like appearance on the leaf surface if the Anthurium's environment is excessively damp and lacks airflow. This can sometimes be confused with mite webbing.
