Paphs are usually easy to remove from their pot. Their roots are of such a nature that they don't adhere tightly to surfaces. If necessary, use a tool for leverage. If you plan to divide the plant, examine it to determine the logical separation point. The stolon between growths is soft and easily broken. Grab a division in each hand and snap the stolon so that you have two plants. If you prefer, you may use sterile shears. This new growth should develop into the next flower - producing growth.

As always, dabbing a little fungicide or fungicide paste on freshly cut parts of the orchid is a good way to prevent potential infection. Pass your shears through a flame for a few moments to sterilize them. Then you may begin cutting away any dead roots. With Paphs sometimes dead roots look no different than live roots. Generally dead roots will originate from the old growth rather than the new lead. Most growers prefer plastic pots for Paphs, but clay could be used if you adjust your culture. Select the smallest pot possible that the stiff roots will fit comfortably in and allow for two years growth. This is a good time to inspect the plant for any pest or other problems.

Determining what media to use will depend on your growing conditions. We are using crumbled rockwool, coarse perlite and a little fine fir bark. Add media all around the plant to within one half inch of the rim. Do not cover the base of the leaves. Because of a lack of thick rhizomes and the usually fine-textured potting media used, Paphiopedilums are among the easiest orchids to repot.
