Paphiopedilum – Cultural Tips

In General, Paphiopedilums or “Slipper Orchids” are terrestrial orchids comprised of approx. 85 species that originate from the South East Asian region. They are a relatively low light orchid with attractive foliage and therefore make ideal indoor plants or companions for other low light foliage plants. LIGHT – Slipper Orchids are a low light orchid, and 1000-1500 foot candles are sufficient. Direct sunlight should be avoided at all times. Light levels can be increased if temperatures are low, and conversely in high temperatures we recommend increased shading. Most types would be found on the forest floor, which is an indicator of the desired level of light required. POTTING MEDIA- With a few exceptions, Slipper Orchids are almost all terrestrial orchids, and enjoy constant moisture at the root zone. Therefore a potting media that holds some moisture but does not stay wet is ideal. For mature plants a suitable mix might be a medium grade of treated orchid bark with the addition of some coarse perlite and shell grit. Younger seedlings would necessitate an even finer potting media. Paphiopedilums enjoy frequent repotting, and a re-pot each year is preferred. This can be done at any time, but we find that Mid Spring is best. WATERING – Without pseudobulbs or other means of storing water, slipper orchids need to be kept evenly moist at all times. We recommend growing slipper orchids with overhead cover so that the watering can be controlled. When plants are grown under shade cloth, extended periods of rain (especially at the wrong time of year) can be detrimental. As a very rough guide (dependant on other factors such as temperature, relative humidity and light levels) 2-3 times per week in Summer reducing to 1-2 times per week in Winter would be an appropriate watering frequency. Water quality is important, with rainwater being best. Most town water quality is
