Help needed on Oncidium repotting

[Dollythehun]

I echo ES. I have that exactly plant and it becomes a beast quickly. I'd pot in a larger pot than Roberta ( sorry) suggested, in small bark with a little spag. You probably can't overwater it and it will take quite a bit of light, too. But, this variety is known for its tendency to throw double spikes. Mine has bloomed twice this year, so it's a worthy plant!
