Phalaenopsis Plant. Potting is usually done every one to three years. Its broad, dark green leaves have a fleshy appearance, and its thick roots are often exposed on the surface of the pot.
The plants will benefit from being moved to a sunnier east / west facing position when the flower stems are fully growing. A combination of cold and draughty conditions is the worst for phalaenopsis orchids. Root rot occurs if plants are left in a soggy medium.
