I wouldn't worry about the lumber. It contains mineral salts of copper,
arsenic, and chromium I beleive. They are chemically bound to the wood, so
leaching should be minimal, especially after a year or so. Copper can
retard root growth to some extent - I don't know how phytotoxic the other
components are but I can't say that I"ve noticed any effects.

I agree once a small amount of time passes there should be no problems.
Copper is used on the inside of flower pots to help plant root growth- the
plants grow and come into contact with the copper and die-thus you get many
mnay smaller root sinstead of one or ywo big roots that twine around the
bootom of the pot.
