I'm looking for a edging for my garden which is non-toxic. I've currently got pressure treated lumber (supposedly it is not arsenic laced). I've been stapling chicken wire to the top of the lumber to keep out rabbits (this has been working), so I'd like to continue to use pressure treated lumber, but as I understand it, they no longer sell it without the chemical treatments.
Is this true? Any ideas as the best way to "seal" off my garden area? I've tried plastic edging and found it incredibly frustrating. I guess if there were some trick to installing it, I'd consider it, but I still need to be able to seal the area off.
