do you treat the wood sides
I am in the process of making a few raised beds. I grabbed a bunch of lumber from Home Depot last week and built to beds. I am going to do 2-3 more, but need to have an oil tank pulled out of the ground where the others are going. (Being done next weekend.)
Anyway, I was thinking about how the wood is currently untreated. Water, dirt, rain, bugs, etc. will ultimately destroy the wood I am using.
So, is there any SAFE treatment I can do to the wood that might help it last a little longer? Water proofing, stain, polyurethane?
