I just received my Orchids monthly magazine and there is an article
on creating an artificial tree in it. I wondered, does anyone on
this list have any experience with doing something like this and if
so, what process did you use. I have a small (8'wx6'lx12'h)
greenhouse that I want to place an epiphyte tree in and would like
to make it artificial so it will not rot.


I have worked with a number of different artificial tree
structures, the biggest one being 15-18' tall, with seven branches.
The base structure for this tree was rebar, with a central core of
pieces, and a perimeter of pieces helping to define the diameter of
the trunk, a little over three feet at the base. All the branches had
rebar going through them which could then be tied onto the trunk
framework. What really gave this tree its structural integrity,
however, was the polyurethane isocyanate (expandable foam), of a type
used to make structures for theatre sets - denser than the expandable
foam spray insulation.
