Building Raised Garden Beds This includes buying list and how-to-do step by step pictures ! Note: I bought a kit for my first raised bed and did this for my 2nd; doing it yourself is MUCH cheaper and allows you to customize the size you want. I was advised NOT to use pressure treated wood due to chemicals in the wood. I am not into my 3rd raised bed, one which I did just for cut flowers, bulbs, etc.. Raised beds better, -less work, less weeds, easier access! ~Barb
