How to create compost

Updated: Jun 12, 2023

Creating your own compost is a rewarding and environmentally-friendly way to recycle organic waste and produce nutrient-rich soil amendment for your garden. Composting involves the decomposition of organic materials, such as kitchen scraps and yard waste, into a dark, crumbly substance known as compost. Here's a step-by-step guide on how to create your own compost:

There are various composting methods to choose from, depending on your available space and needs. The two most common methods are:

  • Backyard Composting: This method involves creating a compost pile or bin directly on the ground in your backyard. It is suitable for larger spaces and allows for more flexibility in terms of composting materials.

  • Composting Bin: If you have limited space or want a more contained system, you can use a composting bin or tumbler. These are enclosed containers that facilitate composting and help control odors and pests.

Select the Right Composting Materials: Composting requires a balanced mix of green and brown materials. Green materials are rich in nitrogen and include kitchen scraps (fruit and vegetable peels, coffee grounds, etc.) and fresh grass clippings. Brown materials are high in carbon and include dry leaves, straw, shredded newspaper, and small twigs. Aim for a ratio of roughly 2 parts brown to 1 part green materials.

Start Layering: Begin by adding a layer of browns, such as dry leaves or straw, to the bottom of your compost pile or bin. Then, add a layer of greens, like kitchen scraps. Continue layering browns and greens, ensuring a good balance between the two. Make sure to chop or shred larger materials to help speed up the decomposition process.

Maintain Moisture and Aeration: Compost needs the right amount of moisture and air to decompose properly. It should be damp, similar to a wrung-out sponge. If it's too dry, add water; if it's too wet, add more dry materials. Periodically turning or mixing the compost pile with a garden fork or shovel helps introduce air and speed up decomposition.

Manage the Compost: Regularly monitor your compost pile or bin. Every few weeks, use a garden fork or shovel to turn the compost, mixing the outer materials into the center. This helps ensure even decomposition and prevents odors. If you're using a composting bin or tumbler, simply rotate or tumble it to achieve the same effect.

Enhance Decomposition: You can accelerate the decomposition process by adding compost activators, such as finished compost or a commercial compost starter. These contain beneficial microorganisms that help break down the organic matter faster. It's important to note that composting will happen naturally even without activators.


If you encounter any issues during composting, such as a foul odor or slow decomposition, it's usually due to an imbalance in the composting materials. Adjust the ratio of green to brown materials, ensure proper moisture and aeration, and avoid adding meat, dairy, oily foods, or pet waste, as these can attract pests or slow down the composting process.


After several months to a year, depending on factors like temperature and maintenance, your compost will be ready to use. It should be dark, crumbly, and have an earthy smell. Harvest the finished compost by sifting it through a mesh screen or simply use it directly in your garden as a nutrient-rich soil amendment
