What is the correct way to re-pot an orchid
1. Unpot the Orchid – Prepare the work area by spreading out newspapers. Turn the plant upside down and thump the sides and bottom of the pot to dislodge it. Once you remove the plant, pry the roots apart and shake off as much of the old potting mixture as possible.
2. Prepare for Repotting – Before it can be repotted, you need to trim the roots using shears or heavy scissors. Sterilize your tools with rubbing alcohol beforehand to prevent spreading viral disease. Remove any dead/damaged roots (mushy and light brown). Cut off any only, leafless bulbs.
3. Repot the Plant – Chose a pot that wil accomodate about 2 years of growth. If using an old pot, make sure to wash it thoroughly and soak in a 10 percent chlrorine solution for 30 minutes, then rinse. If it is a new clay pot, soak it for a few minutes. They need generous drainage so place a layer of plastic peanuts at the base. Before you use the potting mix, wet it with boiling water, allow it to cool, and drain it. When placing the division in the pot, position the older pseudobulbs against one side so that the new lead has room to expand. Pack the dampened bark mixture around the roots, firming it with your thumbs as you go. The top of the rhizome should be level with the top of the bark.
4. Aftercare – To keep the plant upright while its new root system is getting established, stake it securely with a loop of twine or use a "rhizome clip," a simple device that attaches to the side of the pot. Put the orchid in a lightly shaded location and mist both the plant and the surface of the bark twice daily until new root growth is evident. Once the roots have penetrated the bark, move the plant into brighter light and resume normal watering and fertilizing.
