Planting Media for Orchids

Most orchids are epiphytes which don't grow in the soil, but instead attach themselves by means of spongy roots to trees, shrubs, and sometimes rocks. Orchids require a special potting mix of tree fern bark, or a mixture of redwood bark chips, charcoal, and large pieces of perlite. The latter mixture is known commercially as orchid mix and is readily available in bagged quantities. This potting mix allows for quick drainage and air movement around the roots - ideal for healthy plants.
