Two-Spotted Spider Mite Infestation

Spider mites are common pests for Golden Azaleas, especially in hot, dry conditions. They pierce the leaf cells to feed on sap, leaving behind fine silken webbing and characteristic stippling (tiny white dots) on the foliage.

Very Common

High Humidity/Fungal Hyphae

In extremely humid environments, certain fungal growth patterns or molds can appear as a fine, web-like fuzz on the leaf surface. This is less common than mite webbing but can mimic the appearance of silk.
