Two-Spotted Spider Mite Infestation

Spider mites thrive in hot, dry conditions common for Rosa chinensis, feeding on leaf cells and leaving behind fine silk webbing as they build colonies. This disrupts photosynthesis and causes stippling (tiny white dots) on the foliage.

Very Common

High Humidity/Microclimate Mold (Secondary Effect)

While not a primary cause of webbing, extreme moisture trapped within dense rose foliage can create a sticky environment that makes existing mite webs appear thicker and more prominent. This is often accompanied by fungal issues like Botrytis.

Common
