One of the smartest gardening moves you can make is to maintain your own compost bin, but getting started often seems intimidating or too expensive. Fear not! Constructing a simple but effective home compost bin is an affordable weekend project.
Purchase or otherwise procure 27 cinder blocks. 27 blocks will make a compost bin that is three blocks high with nine blocks per layer. Jeanne Grunert, an organic farmer and writer in Virginia, built a compost bin out of reclaimed, recycled cinder blocks.
Clear a space, 4 feet by 4 feet, for the compost bin. Mow the grass short. Remove any weeds or other plants. If the ground is very uneven, till it all up and rake it out to a smoother, more level surface.
Lay nine blocks down, placing them end to end so the holes face inside the compost bin. This will allow airflow. Create a three-sided square from these nine blocks: three blocks on each side, three blocks for the back wall, and the front left open.
Build two more layers of nine blocks each following the same pattern.
Leave the front of the compost bin open for easy access.
