Build a Cinder Block Worm Bin

Cinder block worm bins are indestructible and freestanding, yet movable. (1) Pick a spot out of direct sunlight. (2) Set cinder blocks end-to-end with the open end up in a rectangular shape. (3) Add more rows until you reach your desired height, making sure that each block overlaps they two blocks below. (4) Place hardware cloth on the bottom to exclude burrowing critters. (5) Cover the bin with a piece of exterior grade plywood to keep animals out.  After you add your kitchen waste, be sure to cover debris with a layer of leaves, grass clippings, or wet newspaper.
