Paphiopedilum orchids belong to the sub-family Cypripedioideae, also known as the lady’s slipper family. Unlike epiphytic orchids that grow on trees, Paphiopedilums thrive on the floor of tropical forests in Southeast Asia. With the right care, these orchids can be relatively easy to grow indoors as houseplants. They thrive in high humidity, medium indirect light, and moist soil.

Paphiopedilum Orchid Care Tips

Light

Paphiopedilum orchids prefer less light compared to other orchid types due to their natural habitat along the shaded forest floor. Indirect light from an east-facing window is best, but they can also thrive near south-facing or west-facing windows if shaded by a sheer curtain. Watch for signs of too much or too little light, such as reddish leaves or lack of blooming.

Soil

For optimal growth, avoid using standard houseplant soil for Paphiopedilum orchids. Look for a well-drained mix designed specifically for these orchids, containing ingredients like orchid bark, perlite, charcoal, and coconut husk. Alternatively, lightly dampened sphagnum moss or Rockwool can also serve as suitable growing mediums.

Water

Paphiopedilum orchids have a lower water storage capacity, so they may need more frequent watering than other orchid types. Water them once or twice a week, ensuring the growing medium doesn’t dry out completely. Use rainwater, distilled water, or water from a dehumidifier to avoid damaging the roots with salts from softened water.

Temperature and Humidity

Maintain humidity levels between 40% to 70% for optimal growth. In drier climates, consider using a humidifier to increase moisture in the air. Paphiopedilums prefer temperatures between 60°F and 85°F but can tolerate slightly lower or higher temperatures.

Fertilizer

Feed your Paphiopedilum orchid with balanced orchid fertilizer diluted to one-quarter strength once a week, after watering. Monthly flushing of the growing medium will help wash away excess salts.

While regular pruning isn’t necessary, remove dead or damaged leaves as needed. Propagation can be done by dividing the plant, but be cautious as this process can damage the delicate root system. When repotting, ensure there are several mature growths in the pot before dividing.

Potting and Repotting

Repot Paphiopedilum orchids every two to three years, ideally after flowering and when new growth appears in spring.
