Light: Paphiopedilums prefer bight indirect light. An east window or a shaded West window is ideal for healthy vigourous growth and blooms. In a greenhouse or outdoor environment 20% to 30% full sun, preferably in the morning is adequate light. Foliage should be semi-erect. If foliage appears to be droopy, more light should be provided.
Temperature: Paphiopedilums are generally separated into 2 groups when it comes to temperature, warm growing mottled leaved, and cool growing green leaved. The cool growing paphiopedilums like 60 to 80 day temperatures. The warm growing group likes 75 to 95 during the day. Both groups like a drop in temperature going into the cooler season. If growing in in cooler temperatures reduce humidity to avoid rot.
Water: Paphiopedilums do not have large water storage organs, therefore roots constantly need moisture. Paphiopedilums should be kept evenly moist never allowing the plant to dry out completely.
Humidity: Paphiopedilums perfer 50% humidity when growing at average temperatures. In the home you can use a humidity tray to increase humidity. Misting is not reccommended for paphiopedilums.
Fertilizer: Paphiopedilums are susceptible to root burn if the are not properly fertilized. They should be fed with a during liquid growth fertilizer, such as Dyna-Gro grow during the warmer months. Dyna-Gro Bloom should be used in the fall to promote blooms. Fertilizer should be applied at ½ strength, with every third watering. Remember to never fertilize a dry plant, always water first with clear water.
Potting: Paphiopedilums should be repotted every 1 to 2 years. They should be potted in a medium grade fir mix. Our Gold Mix is perfect for slippers orchids because it will retain more moisture. Sphagnum can be mixed in for water retention. A small amount of charcoal should also be in the mix to prevent root burn due to excess fertilizer. Larger plants can be divided by pulling apart the multiple sets of leaves. Plants should always be centered in the pot with the union of leaves and roots just below the surface of the pottin medium. If you are dividing, plants should soak over night in a
