how to compost using a tumbler
Step 1. Choose a location for your compost tumbler. The ideal location is shaded, close to a water source and close enough to your kitchen that you add compostable materials and turn the tumbler regularly.
Step 4. Add one or two handfuls of garden soil or finished compost to the tumbler (see References 3). Garden soil or finished compost adds beneficial bacteria that helps start the decomposition process.
