My first mounting attempt - questions!

[butterfly_muse]

Afternoon, all.

I am going to attempt to mount my phals - one a large guy, and one a small guy, on some cork bark that I purchased in the reptile section of Petsmart.

The cork bark seems like it has some dirt on it, so I was wondering if you are supposed to pre-clean the bark? Do I need to at least scrub the dirt off?

And what about moss, how much do you mound onto their roots? I am so paranoid about moss because of root rot and phals, so...I am hesitant.

And after they've established themselves, do you take the moss off? Or just the wire to hold them on?

Sorry to ask so many questions!!

Thanks!
