Epiphytic plants are best grown in fast draining media. These plants thrive in conditions and media that allow their roots access to moisture and free-flowing air. In their natural habit these plants grow on top of branches and in the crocks of trees. From this position high above the rainforest canopy epiphytes have the best access to sunlight and rain water or fog/mist.
Some media used in formulating epiphytic planting mixes are:
Fir bark,
perlite,
charcoal,
tree-fern fiber,
coir,
and coco fiber chunks.
Fast drainage and the ability to hold moisture while allowing free air movement at the plants roots are the characteristics these media share. Experimentation as well as some knowledge of what combinations other growers use is the key to successful growing. Your formula must account for your individual growing conditions, your watering habits, and the number of plants you have in cultivation.
