The message
from Janet Galpin contains these words:

I was wondering whether to plant a small willow fairly close to a pond.
It's Salix petiolaris which is a small shrubby tree which apparently
only grows to 12' or so.

I wonder though whether there's a danger that the roots could find their
way through a a butyl liner. I know they can do that very easily to
drainage pipes.


No, they won't penetrate the liner, unless there's a hole in it already.
They get into drainage pipes by muscling in through the joins, growing,
and disrupting the line of them.
