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 you. Best wishes for all, Sherry TheTropix +More _______________________________________________ Aroid-l mailing list Aroid-l@gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l
