Moth orchid care

Phalaenopsis

Thirsty’s starting schedule for Moth orchid: about every 7 days. Check the soil and adjust it to your home.

Watering

Water about once a week, more often in summer heat and a little less in winter. Let the mix dry slightly between waterings but never completely, and don't leave the pot sitting in water. [1][2]

Light

Prefers low light, such as an east-facing windowsill or a well-shaded west or south one. In winter, a bright spot encourages flowering. Keep it out of direct summer sun, which can scorch the leaves. [1][2]

Humidity

Likes warm, humid conditions; you can mist it lightly in summer to raise humidity. [1][2]

Soil and potting

A loose, airy bark-based orchid mix that drains well. Never use ordinary multipurpose or loam-based compost. [1][2]

Pets

Non-toxic to cats and dogs. [3]
