Why does your Monstera thai constellation have fine webbing? Diagnose the cause and fix it with our step-by-step guide.
Spider mites thrive in the low-humidity environments often used for Monstera, feeding on the sap of the leaves and leaving behind fine silk webbing as they build colonies. This is the most common cause of fine, silk-like webs on the undersides of Monstera leaves.
While they do not produce large webs like spider mites, broad mites can cause stunting and subtle silk-like textures on new growth in Monstera. They are much smaller and harder to see with the naked eye, often appearing as distorted, puckered leaves.
In very dry conditions, the fine hairs on some Monstera varieties or the microscopic debris on the leaf surface can become more visible, sometimes mimicking a web-like appearance. This is usually accompanied by crispy, brown leaf margins.
