Join us to learn all about composting with Johnson-Su Bioreactors, a passively aerated, no-turn composting system capable of composting up to 1,500 pounds of material. Gary Dangel and the Walnut Hills gardens have been building and filling Johnson-Su bioreactors for over two years. Receiving food scraps from Walnut Hills residents and Queen City Commons, Gary has diverted over 10 tons of food scraps from the landfill to create quality compost for his gardens.

Together we will harvest and sift finished compost and refill a bioreactor. You'll learn how to build the structure and the process for filling, get a feel for the finished compost, and how this composting method could meet the needs of your garden.

The Common Orchard Project is a program of Green Umbrella that works to install and maintain hundreds of small orchard plantings across Greater Cincinnati and grows “commonly held” resources by educating communities on fresh food and urban land management. Learn more at
