How to Use a Compost Tumbler

Composting is a sustainable and eco-friendly practice that transforms kitchen and garden waste into nutrient-rich compost. One common and efficient tool for achieving this is the compost tumbler. Use this step-by-step guide to learn how to use a compost tumbler effectively, turning organic waste into valuable compost for your garden.


Selecting the Right Compost Tumbler

Before diving into composting, choose a compost tumbler that suits your needs. Consider factors such as size, material, and ease of rotation. Look for a model with proper aeration and insulation to accelerate the composting process. We recommend looking in local buy nothing groups or online marketplaces to reduce the amount of new plastic being used to create these types of compost bins.


Choosing the Right Location

Place your compost tumbler outdoors on a level surface with good drainage. Ensure it's easily accessible for regular turning and adding materials. Position it in an area with partial sunlight to facilitate the decomposition process.


Balancing Green and Brown Materials

Composting is a delicate balance of green (nitrogen-rich) and brown (carbon-rich) materials. Green materials include kitchen scraps, grass clippings, and fresh plant waste. Brown materials comprise dried leaves, straw, and newspaper. Aim for a ratio of 70% brown to 30% green materials for optimal composting.


Adding Materials to the Compost Tumbler

Alternate layers of green and brown materials as you fill the compost tumbler. Chop or shred larger items to accelerate decomposition. Avoid adding diseased plants, meat, dairy, or oily items, as they can attract pests and slow down the composting process.


Maintaining Moisture Levels

Compost needs adequate moisture to decompose properly. Ensure the compost pile remains damp but not waterlogged. If it's too dry, add water during turning. If it's too wet, add more brown materials to absorb excess moisture.


Turning the Compost

Regular turning is crucial for aerating the compost and accelerating the decomposition process. Aim to turn the compost tumbler at least once a week. The more frequently you turn it, the faster you'll get finished compost, so we recommend turning at least once a day if you can.


Monitoring Temperature

A well-functioning compost pile generates heat as it decomposes. Use a compost thermometer to monitor the temperature. Ideally, the compost should reach temperatures between 120°F to 160°F (49°C to 71°C), indicating that the microbes are actively breaking down the organic matter.


Harvesting Finished Compost

Once the compost is dark, crumbly, and has an earthy smell, it's ready to be harvested. This typically takes several weeks to a few months, depending on various factors. Open the compost tumbler and shovel out the finished compost for use in your garden.


Starting a New Batch

After harvesting, start a new compost batch by adding fresh green and brown materials. Use the finished compost to enrich your garden soil, promoting healthier plants and reducing the need for synthetic fertilizers.


A compost tumbler is a valuable tool for those looking to recycle kitchen and garden waste into nutrient-rich compost. By following these steps, you can effectively use a compost tumbler to create a sustainable and eco-friendly solution for your gardening needs. Happy composting!
