Water
Every 7 to 12 days in a 6-inch pot, when the top inch is dry.

| Test before watering | the top inch is dry |
Soil and potting
Two parts potting soil, one part perlite, one part orchid bark.

Common problems
Ranked by how often each turns out to be the cause for this species.
Propagation
Stem cutting in water or soil. Roots in 10 to 21 days.
A cutting without a node will not root. It may stay green in water for months and never produce a single root, because it has no growth point.
