killing trees (was: copper leaching/solubility)

In our neck of the woods, the more expensive copper nails used
for slate roofing because they do not corrode as badly in the air
and water-borne salt as the iron pins (that is the theory) are
hammered into the trunks of trees one wants to kill. I can vouch
this brutal method works, after sadly having to kill an elder
growing in the stone wall at the back of The CoA. Saved it
causing the wall to collapse onto a public highway or us
demolishing the wall to get rid of the tree. It was not an
instant execution... Took two years for the poor thing to
gradually die.

In the same way, a copper penny in a flower display does very
well, because it stops the bacteria making the water anaerobic
and smelly. This alone prolongs the life of cut flowers and saves
changing the water in a vase as often. The copper "poisoning"
would no doubt take longer than the natural life of a flower once
it has been cut.
