If you purchase the ones from a nursery, home improvement store, etc, no
worries. My dad has had one for almost 20 years and it's fine.

How can I treat a half-whisky barrel, to be used for plants, so the
barrel will not self destruct in a couple of years? Is there an
inexpensive, non-toxic oil or preservative that would help?
