Crosscuts of pressure treated wood...
If you crosscut pressure treated landscape timbers, do you need to seal the cut edges to prevent rot and insect damage?
I read somewhere that you need to seal the ends with a wood preservative than contains 2% copper napthenate (sp?). I located a preservative that contains 9% of that chemical.
Is the 9% just more protection or is it detrimental to the soil around it. I will not be using it for my vegetables, but they are nearby, about 5' to 10'.
Or will I be okay cutting the wood and not sealing it as I will be using drainage rock, which will limit the amount of water touching the wood?
