Care in one minute
Provide bright, indirect light; no harsh midday sun.
Use a bark‑based orchid mix with strong drainage.
Water when mix is nearly dry; soak and drain; keep crown dry.
Maintain 65 to 85 °F (18 to 29 °C) with 40 to 60 percent humidity and airflow.
Feed lightly during growth; flush fertilizer salts monthly.
Stake tall spikes early; keep green spikes if side branches are desired.
Watch‑outs
- Bud drop can follow abrupt temperature or humidity swings.
- Tall spikes need early staking to prevent kinking.
- Overwatering and poor drainage can rot roots.
