🌱 How to Care for Spider Orchid to Prevent Aphids?

💧 How to Water

Water every 3-5 days in summer, when the plant is actively growing and blooming, and reduce to every 7-10 days in winter. Allow the substrate to dry almost completely between waterings, but not entirely, to prevent root rot.

☀️ Lighting

Place the plant in a bright spot with strong indirect light—near an east or west-facing window, filtered through a sheer curtain at south-facing windows. Avoid direct midday sun, which burns the leaves, as well as shaded spots, which reduce blooming.

🪴 Ideal Soil

Use a specialized orchid mix based on small-grade pine bark, combined with sphagnum moss, coconut husks, and perlite for excellent drainage. Repot approximately every 2 years when the substrate begins to degrade.
