Re: Building Raised Beds- How To Questions
I actually was just at my local county cooperative extension today and the subject of raised beds came up- someone was asking the same question about lining treated wood. The cooperative extension agent said that people have done soil tests and lining the beds doesn’t keep the treated wood from contaminating the soil, so the extension is really recommending not to do that either. The agent mentioned that his raised beds were made from Hemlock and were 8 years old. He said that the beds would probably need to be replaced sometime in the next few years as they were wearing out where he had screwed them together.
As far as the willow is concerned, this website has all the information!
