Hi, Sarah,

Try to use a pot that is just deep enough to hold the roots and a little
potting medium. I use a mixture of bark, perlite, and charcoal. Also
oncidiums do well with indirect sunlight. An hour or two of direct
sunlight whether afternoon or morning seems okay. But, don't overpot.
Don't overwater nor underwater. The leaves and bulbs will somewhat tell
you if they are too wet or too dry.

Some of the smaller oncidiums seem to do well mounted -- i. e., Onc.
twinkle.

Hi everyone! I have a couple of oncidium intergenerics that I'm going to
repot today. What size pot should I use in relation to the size of the
plant? Do they like to be rootbound? Thanks!
