Orchids have an unearned reputation for being difficult to transplant. Those kept as houseplants are fairly simple to transplant if you keep in mind a few things about how they grow. For example, orchids prefers a pot-bound environment. When selecting a new pot, pick one only slightly larger than the one from which the orchid will be moved. Orchids rarely need to be transplanted, but they should be moved when new growth develops outside the pot — once every two to three years.
Prepare the new pot by placing a 1-inch layer of gravel in the bottom for drainage. Add enough orchid potting mixture to the bottom of the pot to ensure the plant will remain at the same height in the new pot as in the old one.
Remove the orchid from its current pot by gently tipping the pot and grasping the plant by the base. Wiggle the plant out gently to avoid damaging it. Inspect the roots for rot. Remove any damaged roots using bypass pruners.
Place the plant and root ball into the center of the new pot. Fill around the root ball with new orchid potting mix until the plant is held snugly in place. Water the re-potted plant thoroughly.
