Moth orchid
Phalaenopsis amabilis
Moth orchid wants bright indirect light and water every 5 to 10 days, once the roots in the pot have turned from green to silver. Non-toxic to cats and dogs. It climbs: without support its leaves stay small.
Light
Bright indirect
LowMediumBright indirectDirect
An east window, or a metre back from a south one. Leaves should be mid-green: dark green means too little light, reddish means too much.
Water
Every 5–10 days
Baseline for a 6-inch pot indoors. Check first: water when the roots in the pot have turned from green to silver, not on a schedule.
Humidity
50% and up
Wants 70%. Struggles in dry winter air.
Difficulty
Easy
Scores 2 of 5: Scores 2 of 5: undemanding once the potting medium is right. Nearly every failure traces to being potted in soil or watered on a schedule.
Habit
Rosette
Needs a moss pole or board. Not decorative — leaves will not mature without one.
Non-toxic to cats and dogs
Eating a large amount of any plant can still cause mild stomach upset.

Light
Bright indirect light. An east window, or a metre back from a south one. Leaves should be mid-green: dark green means too little light, reddish means too much.
Water
Every 5 to 10 days in a 6-inch pot, when the roots in the pot have turned from green to silver.
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 roots in the pot have turned from green to silver |
Soil and potting
Bark only: two parts medium orchid bark, one part sphagnum. Never standard potting soil, which suffocates the roots.
Repot roughly every 2 years, or when roots come through the drainage holes and water runs straight through without absorbing.
