Hi folks. I'm looking for some cedar lumber to build raised beds in my garden this year. Any suggestions on a good place to buy rough hewn cedar for this purpose? Or do you have another suggestion for raised beds that keeps the cost down? I've got a 40'x40' garden space on a hilly spot that tends to wash with heavy rains. I think level, raised beds will help with the erosion in my garden. I'd like to start with (5) 4'x8' raised beds this year and add more later. Any input is most appreciated!
