White Oak as Mounting Wood

[gdupont]

Hey ya'll,

A few days ago a tree fell at the end of our street. it was pretty big, rotted on the inside, etc. White Oak tree. There were a lot of pieces of bark lying around so I snagged as much of it as I could for my orchids.

So, I have a few questions:
1) if I were to mount an orchid on one of these pieces, is there anything I need to do to prepare the bark?

2) Does White Oak work? Anyone have experience with it?

Thank you!
