✅How do Compost Tumblers work? Simple. You load them with green and brown waste from your yard and kitchen. When full, you give them time to work, in other words, heat up. Turning a compost pile mixing the organic materials and the organisms it contains with heat-producing oxygen is the traditional method of keeping the process going full steam. By turning the tumbler, the organic materials are mixed and infused with fresh oxygen.

✅Easy to Access Finished Compost: Just Slide the door open and take the organic fertilizer out when the compost is ready. When a check reveals the compost is complete —and this can happen in a matter of weeks —the same access that allowed you to fill the tumbler lets you empty it. Now is the time to spread the results.
