This blend contains everything your orchid could be for. Orchids are a little different to most houseplants. As most orchids are epiphytes (plants that don't grow in soil) they prefer a substrate with lots of aeration and space. 

To support this there is lots of orchid bark. The sphagnum moss helps retain humidity around the plant roots. Orchids will also do well in terrariums! The perfect general orchid mix.
