Environmental Stress (Low Humidity)

While not a direct cause of webbing, extremely low humidity can cause rose foliage to desiccate and weaken, making the plant more susceptible to mite outbreaks. The fine lines may sometimes be mistaken for early-stage silk production during periods of heavy drought stress.
