The bed shown here got worked on last weekend. I dug it over as deep as I could with my garden spade, then moved the dirt aside and tried to get most of it dug twice as deep as that. I was helped along in my cultivation by the tree and bush roots I had to keep tearing out, some a half inch wide and running the length of the bed.
This is a 8 foot by 6 foot bed, with the center 2 feet raised an additional 6 inches. I put three rows of carrot seeds up top there. The two bottom sections both got three rows of beet seeds planted in them. I have NEVER been successful at growing a beet in my garden, but I have high hopes that I’m somehow doing something different this year.
