How to Compost Efficiently in a Tumbler for an Eco-Friendly Garden

How to Compost in a Tumbler: A Beginner’s Guide

Composting is not only a sustainable way to reduce waste but also an excellent method to produce nutrient-rich soil for your garden. If you’re new to composting or looking for a convenient way to compost at home, using a tumbler can be the perfect solution. In this blog post, we will guide you through the process of composting in a tumbler step by step.

Choosing the Right Tumbler

The first step towards successful composting is selecting the right tumbler that suits your needs. Consider factors such as size, material, and features when making your choice. Opt for a tumbler with adequate capacity for your household’s waste output and ensure it has good ventilation and easy-to-use turning mechanisms.

Gathering Compostable Materials

To create high-quality compost, gather both green (nitrogen-rich) and brown (carbon-rich) materials. Green materials include kitchen scraps like fruit peels, vegetable trimmings, coffee grounds, and grass clippings. Brown materials consist of dry leaves, shredded newspaper or cardboard, straw/hay, and small twigs. Aim for a balanced ratio of approximately 50% green matter to 50% brown matter.

Filling Up Your Tumbler

Add an initial layer of coarse/bulky brown materials at the bottom of your tumbler as they help with airflow during decomposition. Then alternate layers of green and brown materials while ensuring they are finely chopped or shredded – this facilitates faster breakdown into rich humus.


  • Mix moist ingredients like food scraps with dry ones like dried leaves or newspaper strips.
  • Avoid adding meat, dairy products, or oily materials as they can attract pests and lead to unpleasant odors.
  • Consider periodically adding a compost activator or starter that helps speed up decomposition.

Turning and Aeration

Your compost tumbler requires regular turning and aeration to maintain optimum conditions for decomposition. Rotate the tumbler every few days by spinning it on its axis. This action incorporates oxygen into the mixture, allowing beneficial microorganisms to break down organic matter faster. Aim for at least one complete rotation per week.


  • If your tumbler does not have an internal mixing mechanism, use a garden fork or shovel to turn the contents manually.
  • Avoid overfilling the tumbler as this may hinder proper airflow and slow down the composting process.

Maintaining Moisture Levels

Compost needs moisture for microbial activity but should not be too wet or dry. Aim for a damp sponge-like consistency throughout the pile. If your mix is too dry, add water using a hose or watering can; if it’s too wet, incorporate additional brown materials like shredded cardboard to absorb excess moisture.

The Composting Process: Patience Required!

Composting in a tumbler typically takes around 2-6 months, depending on various factors such as temperature, humidity level inside the tumbler, and how well you manage maintaining ideal conditions (aeration and moisture). Regularly monitor your compost’s progress by checking its color (should turn dark brown), texture (crumbly), and smell (earthy).

Harvesting Your Compost

Once your compost has fully transformed into rich humus, it’s time to harvest and use it in your garden. Open the tumbler’s access door or remove the composting drum (depending on the design) and collect the finished compost. Use a screen or sieve to separate any remaining larger chunks from your desired fine-textured compost.

Final Thoughts

Composting in a tumbler is an efficient and convenient way to recycle organic waste into valuable soil amendment. By following these steps, you can successfully create nutrient-rich compost for your plants while reducing landfill waste.
