Light
Bright indirect light. An east window, or three feet back from a south one. Variegated cultivars lose their pink in anything dimmer.
Water
Every 7 to 14 days in a 6-inch pot, when the top two inches are dry.
Treat the interval as a starting point and the test as the actual instruction. Pot size, light level and season all move the number.
| Method | soak and dry |
|---|---|
| Test before watering | the top two inches are dry |
Soil and potting
Three parts potting soil, one part perlite, one part orchid bark.
Repot roughly every 2 years, or when roots come through the drainage holes and water runs straight through without absorbing.
