Question:
I’m thinking of putting in a raised bed and wondering what kind of wood to use for the border. If I use pressure-treated wood will it leach into the ground and contaminate the plants?
Thanks for your help …
Rick
Answer:
Hi Rick: I recommend using regular kiln dried. Avoid the pressure treated. PT would last longer but as you probably know it is treated with a host of preservatives, including arsenic. Though I’ve never seen a study tracking leaching of these substances into soil in a raised bed, I’ve never talked to anyone who think it’s worth the risk. Good luck with the raised bed!

Hello,
I am not positive what is used in PT, but I know that the preservitives has changed over the past years!
