RE: ban treated wood

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hello Chuck:

I have seen wolmanized wood around for many years. It definitely has a
better appearance,  I would like to find out more about the process, and
what is the definition of non-toxic. Would you eat vegetables grown from
planters made from it?
