Orchids: Basic Repotting & Dividing

Most orchids need to be repotted once every two years. The bark or moss that the orchids are grown in gradually deteriorates. If repotting is not done, the bark or moss become decomposed and packed. Under these conditions, roots are not properly aerated, drainage becomes blocked so there is too much standing moisture, and the plant eventually dies from asphyxiation and root rot. Ideally, orchids should be repotted immediately after flowering.

Selecting a New Pot
Orchids can be grown in any kind of container that has a hole for drainage at the bottom. Because ventilation around the bottom of the pot is vital to the plant's well being. Water must not be allowed to stand at the bottom of the pot. The same pot may be re-used after the existing decomposed orchid bark has been discarded. However, the used pot must be disinfected with Physan 20. Otherwise, pick a pot that is just slightly larger than the previous one. The pot should be large enough to accommodate for the plant's growth over the next years.
