🌱 How to Care for Fringe-lipped Dendrobium to Prevent Scale Insects?

💧 How to Water

In spring and summer, water when the mix is almost dry, usually every 4-6 days, and never leave the pot standing in water. In autumn and winter, water less often (every 10-14 days) without letting the canes shrivel.

Use a medium-grade bark orchid mix with some perlite, sphagnum moss or coir, kept airy. It also grows well mounted on cork or tree fern, where the canes hang down.
