I am going to leave these questions to others that currently mount more than I do. I am sure that others will have suppliers that may have better prices and they can instruct you better in removing a plant from a mount. I have done it, but was never happy with the results as I ended up really damaging the root system.
So - someone chime in and help this member out!!
Will still be monitoring the post as I want to see what others have to add to the thread!
