I started this garden in the fall to make sure the soil would be ready for planting in the Spring because I am doing a kind of Hugelkultur bed.
I used some of the concrete bricks that would ultimately become the wall of the garden to lay out space for it on the ground. It will have three rows of bricks for each wall. I plan to fill it like a Hugelkultur bed. It will be layered with gravel, sand, dead trees, compost matter, and garden soil.
