Why does your Ficus benjamina 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 warm, dry indoor environments common for Ficus benjamina. These microscopic arachnids pierce plant cells to suck out sap, causing leaves to lose chlorophyll.
This specific species is highly prevalent in ornamental Ficus plants kept in low-humidity settings. The webbing acts as a protective silk structure for their colonies and egg sacs.
While not a primary cause of webbing, extreme lack of humidity can stress the Ficus benjamina, making it much more susceptible to mite outbreaks. This physiological stress weakens the leaf cuticle, allowing pests to penetrate easily.
