I know some of you garden. I have above ground beds. About 8 years ago we installed treated lumber around the beds thinking that would last a long time. Well I discovered this morning that the boards are getting really rotten from the inside of the bed out. They will last this summer but need to replace in the fall. I have 8 beds that are 8-10ft. long and 3 ft. wide. I need something that will last a LONG time and not be outrageous on price. Any help would be appreciated. The treated lumber we used sucked as far as I am concerned. :
