Moth Orchid
Phalaenopsis
The Phalaenopsis orchid, commonly known as the Moth Orchid, is prized for its elegant, long-lasting blooms that resemble the wings of a moth. Native to Southeast Asia, these epiphytic plants grow on trees in the wild, drawing moisture and nutrients from the air and rain. They are among the most popular indoor orchids because they thrive in typical household conditions and can bloom for several months at a time.

Care Guide
Light
Place in bright, filtered light such as an east-facing window. Avoid direct midday sun which can burn the thick, leathery leaves.
Watering
Water approximately once a week when the potting medium feels nearly dry. Use lukewarm water and avoid getting water into the crown (center of the leaves), as this can cause rot. If possible, water in the morning.
Temperature and Humidity
Ideal temperatures are between 65°F and 85°F. To encourage blooming, a slight drop in temperature at night during the fall can be beneficial. Maintain humidity between 50-70% using a pebble tray or humidifier.
After-Bloom Care
When the flowers fade, you can cut the spike back to the base to let the plant rest, or cut just above the last node to encourage a secondary flush of flowers.
Repotting
Repot every 1-2 years using a dedicated orchid bark mix once the medium begins to break down or the roots outgrow the pot.
