🌱 How to Care for Spider Orchid to Prevent Grey Mould?
💧 How to Water
Allow the substrate to dry almost completely between waterings—water in the morning and increase frequency during the formation of new shoots and flowering. Avoid letting the plant sit in standing water, as the roots rot easily.
☀️ Lighting
Provide bright indirect light, such as near a window with a sheer curtain. Direct midday sun can burn the leaves, while environments that are too dark will hinder flowering.
🪴 Ideal Soil
Use a well-draining substrate specifically for orchids, based on orchid bark, with perlite or sphagnum moss to retain some moisture without soaking the roots.
