ð§ How to Water
Water thoroughly and let the mix dry almost all the way through before watering again, roughly every 6-8 days during active growth and less often in cooler months. Silvery-green (not white or soggy) roots are the cue to water again; never let the pot sit in standing water.
âïļ Lighting
Give bright, indirect to lightly filtered light, such as an east-facing window or a shaded south or west window. Leaves should stay a light chartreuse-green; dark green means too little light, reddish leaves mean too much.
ðŠī Ideal Soil
Pot in a coarse, well-draining orchid bark mix (medium-grade bark, optionally with added sphagnum or perlite) in a container sized for just 2-3 years of growth. Repot roughly every two years once the bark starts to break down.
