Why does your Begonia Monza Formula Mixture have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
The presence of fine webbing is the classic hallmark of spider mites, which thrive in the warm, dry environments often preferred by Begonia Monza. These pests pierce plant cells to suck out nutrients, leading to stippling and eventual leaf drop.
While usually more 'cottony' than web-like, certain stages of aphid infestations on Begonias can create a fine, waxy silk appearance around new growth and leaf axils.
Begonia Monza requires high humidity; if the environment is too dry, the leaf edges can become brittle and fine, hair-like strands of dried organic matter or dust may appear to mimic webbing.
