Why does your Begonia grandis have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The presence of fine webbing is a classic sign of a spider mite infestation, which thrives in the warm, dry conditions often found with Begonia grandis. These tiny arachnids pierce plant cells to feed on sap, causing stippling and eventual leaf drop.
A specific subset of mites that is highly aggressive on Begonia species during periods of low humidity. They create dense silken webs around the stems and leaf undersides to protect themselves from predators.
While not a direct cause of webbing, extremely dry air can cause Begonia grandis foliage to become brittle and fragment. In some cases, the fine debris or structural breakdown of desiccated leaves can be mistaken for light webbing.
