When should I re-pot my Orchid? By David Off of Orchidnerd.com

When an orchid plant starts to grow over the edge of the pot, it is time to re-pot it!

Orchid plants need re-potting for one or a combination of two main factors: Potting mix breaks down, often evidenced by dead roots, or the plant outgrowing the container. In the first case, a larger pot may not be required, simply replace the growing medium. In the second case, the plant may need dividing or may be shifted into a larger pot. Fresh media should always be used. A good general rule of thumb is to pot for the bottom of the plant, the root system, and not for the top, the foliage.
