Avoiding toxic soil in raised garden beds
My husband, bless him, bought treated wood to build me four large raised garden beds so I can plant veggies and flowers. He's got them built when I think to ask if he used treated wood - and he did. So now I'm wondering what's a safe wood sealant that he can put on the wood so the chemicals don't leech into the soil? Can we use a spar varnish on the inside? Any suggestions or advice would be most welcome. Thank you!
