repotting an oncidium currently in reg potting mix?

[carriek]

Hi all / anyone!

I have an oncidium hybrid from Trader Joe's. It was lovely while it was blooming and amazingly, I have yet to kill it. Apparently it's the lucky number three!

Now that it's done blooming, NOT dead and actually showing growth of new leaves I thought I should figure out how to care for it. I looked around the internet and apparently it should be planted in bark chips. Right now it looks like it's in regular potting mix, like what you'd use for starting seeds or planting pretty much any kind of houseplant.

So my question is - don't fix what's not broken - and leave it in regular potting mix - or thank my lucky stars and move it to a bark / moss mixture? I'm inclined to stick with what seems to be working, but my two rather dead oncidiums say to not trust my instincts entirely.

Any help / thoughts / advice would be appreciated!

Thanks so much!
