Thankfully I was able to find a wonderful deal on cedar lumber in middle Tennessee, and be able to design the central part of our Main Farm Garden! Each bed is made with industrial grade cedar boards that when assembled form sixteen 4x8 garden beds with a 10" height. The bottoms are lined with manured goat shavings, and we ordered 15 yards of Holy Cow garden compost to fill the rest! I am LOVING my new Craftsman drill from Lowe's and putting these beds together (over 300 screws) was a piece of cake! There are gaps on the sides, but since the bottom manured layer has hay in there as well from the goats, I'm going to give it a try and pray it doesn't wash out of the sides. A lot of trial and error in permaculture - the only way to learn! I'd rather try that though than custom cut all those side pieces, which is both wasteful and a pain in the rear! Our wonderful neighbor came and helped me cut the 4x4's in half that secure the top frame to the bottom board, and I will be getting a Ryobi miter saw so that moving forward I can do that as well! I have built three greenhouse benches, and using a hand saw is just NOT going to cut it (no pun intended!) anymore! Going to Lowe's and adding on to my tool collection is my kind of outing! LOL. More soon!!
