I have used pressure treated timber to make some raised beds for vegetable growing. The garden is sloping so I'm now going to level them using timber cut at an angle. The 'cut' side of the timber will be in contact with the ground and I'm concerned about it rotting due to the pressure treated surface having been cut through.
Does anyone know if this will be a problem and if so how to alleviate it eg should I put a layer of plastic between the timber and the earth? I though about treating it with wood preservative but the timber is very wet and the preservative is not suitable for 'wood used for growing food'.
Any ideas?
