Orchid bark: which plants need it and which do not
37 of 100 species in this database need it
37 of our 100 species need it. Look at where the plant grows in the wild. Typically $12 to $30.
Look at where the plant grows in the wild. If our entry says canopy epiphyte, its roots evolved clinging to bark in open air, and bark in the pot mimics that. If it says tropical understory or arid, you probably do not need it.
Depends on the plant. Essential for epiphytes and aroids that climb. Pointless for succulents, and actively wrong for a moisture-loving fern.
What it actually is
Chunky pine or fir bark that creates large air gaps and breaks down slowly. It turns a dense potting compost into something an aerial root can actually breathe in.
What to avoid
Do not use it as the whole medium for anything except a true orchid. And do not reuse old bark — once it has broken down to crumbs it holds water like soil and defeats the purpose.
Species in this database that need it
These species have bark in their recorded recipe, either as an aroid mix component or as the entire medium.
