potting media for oncidium ampliatum

[Plantmaven]

I would just like to add (in case anyone is still reading this topic) that mine was so wildly growing, I could not keep it on my humidity tray with other orchids. I ended up mounting it on a long cork slab purchased at a pet store. It seems to love it -new roots are growing. And because it likes free draining and dry out period, mounting seems to make it happy. I do have some sphagnum moss behind it on the cork slab to keep it moist for a few hours. It is watered every morning.

I have mine mounted too. Big hollow section of box elder. It seems to love it as the plant is getting huge.

Only you can decide what works for your home environment. For me my Onc do best in a plastic pot with extra holes. The mix I use is one I make. I use Fine bark and perlite. I always add a dash of Sphagnum moss that is chopped up. This mix works me and how I care for my plants.

I could never mount all my Onc and have them do well. It is just too dry here. I am too busy to water everyday. So that would never work for me. I need something that holds in moisture well but drains well too.

For my orchids that like to always be moist like my miltoniopsis I use Peatmoss and prelite.

It took me a little while to find what mix worked best for me, but I have it down now.
