Will Elmer's hold up to moisture?

Seems to, but for how long I won't say. We have used it to fasten bromeliads
to driftwood, but we also used some ties along with it. Think about how we
mix Elmer's with cinnamon for a fungal paste; seems to hold up pretty well.
If I were tying an orchid to a tree I'd use more than either Elmer's or
Liquid Nails, I think. A little wire or some old pantyhose (which works
better than wire, really) along with the glue makes for a secure attachment
until the plant takes hold.
