Great for arid climates, this keyhole gardening article sums it up nicely. Don’t know if it would work in the sopping wet northeast, but I love the idea! Looking at the side-view cutout it reminds me of a hugelkultur bed where you bury logs covered by the branches covered by the leaves covered by garden soil. The compost basket in the center would speed the decay of the materials at the bottom, bringing both moisture and nutrients to the sub-soil biology. Oh, and let the birds do their business right into the bin as well.
