Orchids are incredibly popular houseplants, thanks to their exotic looking flowers. But unlike other houseplants, most orchids are epiphytes and they need special media in which to grow.
Some of the most common ingredients in commercially available orchid mixes are chopped tree fern fiber, chopped fir tree bark, osmunda fiber, charcoal, and volcanic rock. These materials all help to create the loose, well-drained environment that orchids crave.
Every two years or so you’ll need to replace the orchid growing media for each of your plants.
With a little online research and experimentation, you can easily figure out the best growing media for your orchids, and then create the well-drained environment that these unique plants need.
