How to Choose a Potting Media
The potting media you use should be based on the moisture needs of the particular orchid you are repotting. For instance Phalaenopsis orchids like a potting media which holds a bit more moisture than Cattleyas or Dendrobiums. As an example, let’s look at a couple of different orchid potting mixes from Better-Gro®.
Better-Gro® Special Orchid® Mix is an airy, quick-draining mix that is ideal for those orchids that like the media to dry quickly between watering. This media is ideal for most epiphytic orchids such as Cattleyas, Dendrobiums, Oncidiums, etc.
Better-Gro® Phalaenopsis Mix is designed to drain well but holds moisture a little longer to meet the needs of Phalaenopsis orchids, which prefer a more constant level of moisture.
Many orchids can also be planted directly into a high grade sphagnum moss, such as
Better-Gro® Orchid Moss.
