What can you treat white pine planks with so i can use them in a raised garden bed?

I have these white pine planks that are the perfect size (9"x10'x1") for my raised garden bed. I am hoping that there is something I can treat them with so they would last at least a couple of years and not attract wood loving bugs (termites or borers) I plan to use this for my vegtable garden. Any ideas??

Any water seal will help. However, you can't paint it. You might be able to paint one side and get away with it.





That size of board is a good size board. You might be ahead to sell them and buy pressure treated lumber for this.





Or, you can buy dog eared board planks that are used for replacement flat board fences. These are really cheap. You would just need to drill two holes on either end and could screw in a wooden tomato stake that will hold as well as the pine and will be cheaper.
Reply:Thompson's water sealer should give you at least 5 years. If you use pressure treated lumber it will last at least 10 years. I pulled a couple of my pressure treated boards (after 11 years) last year to check the inside and they look like they will probably give me at least another 2 years before I have to start over.
Reply:Pine rots pretty quick I have used 18x24 patio stones (used ones) on edge ,dug into the ground lasts forever. save the boards for something else
