Water when the airy bark medium and roots show that the plant has dried enough, while preventing the roots from remaining soggy.
Moth orchid watering
Check the bark and roots before watering Phalaenopsis orchids. Water when the airy medium has dried enough, let excess drain, and keep roots from sitting in stagnant water.

When to water
Let light, temperature, humidity, bark condition, and root growth change the watering interval. Cooler, lower-light winter conditions generally slow the cycle.
How to water thoroughly
- Check the bark and roots, water thoroughly enough to wet the medium, and let excess water drain before returning the pot to its place. Exact soaking duration is not established.
- Use an airy bark-based orchid medium and a container that lets water leave freely. Do not leave the roots sitting in stagnant water.
Signs of too much or too little water
Wrinkled leaves or dry, shriveled roots can signal too little water or root damage, while roots that stay wet increase the risk of decline. Inspect bark and roots before changing the routine.
