Above ground box garden
Sorry if this is not specific to a particular vegetable but this was the most logical forum I could find for this one.
I am planning to expand my garden and build a 10x12 above ground box garden. I had read that you should not use pressure treated wood because the chemicals will leech into the soil. Is this true? I had heard it's not as much of an issue now because they stopped using arsenic in pressure treated wood years ago.
Anyway, if not pressure treated, what kind should I use? Any insight is appreciated!!!
