As always, begin your potting session by sterilizing your cutting tools. Remember to sterilize before each plant. This Oncidium is growing over the edge of the pot and is ready to be repotted.  Squeeze the plastic pot all around to loosen the plant. It should easily lift out. If not, use a lever to gently pry the plant out of the pot. If the Oncidium is in a clay pot, use a knife or lever to free the roots and remove the plant.  Although this plant is overgrown, the roots are in pretty good condition and there is a nice new growth. It should establish itself quickly in its new pot.

Loosen the root mass and remove the old potting media with your fingers. If there are any old pseudobulbs at the back of the plant that are leafless or severely shriveled you can remove them for a better fit in the new pot. Dress the cut with fungicide. Remove any old bloom spikes. Cut away any old dead roots. It should be easy to tell dead roots from live roots with most Oncidium alliance orchids. Live roots will be firm and generally white. Dead roots will be soft and generally brown.

Select a pot that will allow for about two years growth. Choose plastic or clay based upon your growing conditions and watering habits. We will use fir bark mix for this Oncidium. Place some drainage material in the bottom of the pot. Place the orchid with the oldest part against the rim of the pot and the new growth toward the center. Add Better-Gro® Special Orchid Mix all around the pot to within one half inch of the rim. Do not cover the base of the pseudobulbs. Press the media down to firm it against the orchid roots.

With the availibility of hybrids such as Oncidium Sharry Baby and Colmanara Wildcat, the Oncidium alliance offers satisfying orchids to grow. They are easy to repot too!  
Prepare a nametag with the name of the plant. You can also add the date if it will help you decide when to repot the next time.
