How to Grow

Cultivation

Under glass, grow in an open, ericaceous, well-drained, but moisture-retentive mix, which can include, lava rock or pumice, fine fir bark and leafmould or chopped sphagnum moss, choosing a position in bright but diffused light. During the growing season, allow the surface of the compost to become just dry before thoroughly watering the compost. Avoid plants sitting in water which can cause the roots to rot. Apply a liquid houseplant fertiliser monthly during April to September. Water less frequently in winter, when growth slows right down, and stop feeding until the spring. Repot every 2-3 years.
