Hi Charles,
Just building my raised beds now with 45mm X 220mm timber treated with Tanalith. I’ve been researching what to treat the timber with as an extra as I’d like them to last a long time. The OSMO treatment looks expensive, but I’m sure it will do a good job. I’ve come across a product called Bird Brand Ecosote that promises that it is non-toxic. It is said to contain 2 active ingredients (boron & biocide). Firstly do you think this would be safe to use and secondly, is it actually worth doing it as the timber is already treated with Tanalith? I would at least like to treat the edges that have been cut. I’m keen to get the beds made and get them filled. Thanks in advance. I wonder if anyone on the forum has used this before.
