Similar to the great flamingo, the moth orchid is native to Southeast Asia, with greatest concentration in the Philippines, Indonesia and Malaysia. Most epiphytes require a coarse, well-drained media. Coarse bark chips work well for most orchids. Typical houseplant soil mixes, like peat moss, retain too much moisture. Depending on the amount of growth, moth orchids can be repotted in fresh bark chips every year or two.
Moth orchids grow best in bright, indirect light.
Direct sun actually may burn the foliage turning the leaves yellow and brown. Plants in a south window will need to be shaded with a sheer curtain. Phalaenopsis orchids in poorly lit areas will not grow or flower well. Fluorescent lighting can be used to supplement natural lighting in poorly lit areas. Hang the fluorescent fixture 6 to 8 inches above the plants.
