Composting Systems

Tumblers and Turning Systems

hc-system-2

Turning systems can be multi-bin, tumblers or rolling spheres. Batches of compostable materials are mostly made up of a combination of green and brown garden materials (make sure they are chopped up). Some food scraps can be added when the batch is made or when the materials are turned for the first time. For multi-bin systems, the heap is turned every week or two and then allowed to mature for a month or more. Compost can be ready to use in 6 – 12 weeks, but remember to keep it covered from the rain and check regularly for moisture levels during dry, hot weather. For tumblers and spheres, materials can be added as they are generated but making up a batch of materials is best to get it started. Through regular turning of the barrel or sphere, materials are mixed thoroughly and compost quickly.

Suitable Materials: Soft landscape materials to start with, e.g. grass cuttings, weeds, leaves, old plants, flowers, etc. Plant based food scraps can be incorporated into the mix at the start or can be buried into the composting materials once the composting has started within the first week or two.

Main Advantages:

  • Produces high-quality compost in as little as 6 – 12 weeks when done properly.
  • Multi-bin systems are ideal for the avid gardener with lots of outdoor space who doesn’t mind the work and wants all the compost the system can produce.
  • Hot composting systems are effective in killing weed seeds and plant diseases.
