What is the Ideal Pot-Size for Phalaenopsis Orchids?
Planting your Phalaenopsis orchid in an appropriately-sized pot can help it grow better. Basically, the pot has to be big enough to contain the roots without cramming them. However, it cannot be too large either, or it will lead to watering problems. Below are tips on how to choose the right pot size for Phalaenopsis orchids:
Phalaenopsis orchids are typically sold as matured plants that are capable of producing flowers. The sizes of pots in which they are planted vary according to their natural sizes, habits, and species or hybrids. When they are in the nursery, Phals are usually grown in pots that measure 4 to 6 inches in diameter. Larger pots are required for growing larger plants that have more leaves and roots. Pots of the same size can be used for about two years, and then, they have to be replaced with pots that are 1 inch larger in diameter when the orchids are repotted, which should be done once every one to three years. The pots should be big enough to prevent toppling when they are set on a flat surface.
Growing Medium and Pot Size
The best potting materials for Phalaenopsis orchids are those that allow water and air to move freely around the roots, such as bark and peat-based media. These potting media decompose at a relatively fast rate, making it necessary for the plants to be repotted every one to two years.
Stabilizing Orchid Pots
Most growers plant their orchids in plastic or vinyl pots these days. These pots are light, and they can easily tip over. However, you can place them in larger terra cotta or ceramic pots to prevent toppling.
