There's nothing on the market (that I know of) that is any use for

I thought about creosote, which I think I could still get at the ag coop,
but even if I wanted to deal with the whole nasty and toxic mess the
situation is complicated by the fact that I've trained climbing roses to
quite a bit of it that gets full sun. Oh well, the lichen is pretty
anyway.
