The Compost year : Composting sweetcorn plants
Today we received the first of this year’s sweetcorn plants for composting at the Stokes Wood Compost Demonstration site. Most home composters will have composted sweet corn kernels, husks, and the central cob itself as part of their kitchen waste.
The kernels compost quickly, and the husks can also be added directly to the bin. The central cob will take longer and are best cut into small pieces to expose the maximum surface area to the compost microbes. However, if left whole the cobs will provide space for air pockets in the compost although they will take longer to breakdown. If not finished in the first cycle they can always be added to the next bin.
On the allotment we receive the finished plants, although these may include some small cobs that have not fully developed by the end of the season. The stalks are quite thick but when green are easily cut inro manageable lengths with garden shears. I do not cut mine to the 1-2 inches recommended for fast composting but aim for about 6 inches to make it easy to turn when aerating the bin contents. If allowed to dry, after cutting. When starting a new bin at this time of year a layer of sweetcorn stalks can be added to form a base layer to allow airflow into the heap.
