  RE: [Aroid-l] Off topic protective coating over Driftwood
From: "Sherry Gates" <TheTropix at msn.com> on 2007.02.05 at 19:53:49(15224)
Hi everyone,
I hope you are all well and your plants are thriving. I
have mixed thoughts on this subject. I would advise against sealing
the driftwood once the plants are growing on them. Not because I think the
sealant would be harmful (toxic) to the plants, but I do think it could 'clog'
the pores on the leaves (and other parts) and could harm or kill them
by hindering, or halting altogether, the various gas or nutrient (or
water!) exchange. We've all seen many plants (Ivy, some
philodendrons, epiprimnum...) attach themselves to decks and houses
(with wood siding) that have previously been stained and sealed whether
with polyurethane, or other sealant, and do great. But the plants are
removed when the wood is re-sealed so you get complete coverage. Maybe if
you have a small 'sacrifical' epiphyte you could spray some of the sealant on
it and see if it does ok. If the product of your
choice has a 1-800 number, give them a call and ask if they know.
Now I'll go back to the back and mind my own business while I learn from all of

Best wishes for all,

Sherry TheTropix
