Understanding Compost

What is compost?

Have you ever asked yourself what compost is and what it's used for? Compost is organic material that has been decomposed and recycled as a fertilizer and nutrient-rich soil. It is created through a process called composting, where organic waste such as your everyday food scraps and yard trimmings breaks down over time through the action of microorganisms, fungi, and other organic decomposers. The result is a nutrient-rich, dark, earthy substance that can be used to enrich soil, support plant growth, and reduce the need for chemical fertilizers.

What does compost contain?

Compost contains 4 important natural components:

Green Materials are nitrogen-rich materials, like fruit and vegetable scraps, coffee grounds, and grass clippings. They help to provide the necessary nitrogen for the composting process.

Brown Materials are carbon-rich materials, like dried leaves, straw, wood chips, cardboard, and paper. They provide the carbon that is needed for microorganisms to break down organic matter.

Water is essential for the composting process, as it helps to maintain moisture and activate microorganisms. The compost pile should be kept moist, but not saturated.

Oxygen is another necessary element for aerobic microorganisms to thrive and efficiently break down organic material. Turning or aerating the compost pile helps ensure that it has enough oxygen to decompose properly and quickly.

What are the benefits of composting?

Did you know that compostig is not only beneficial for reducing food waste? Here are the 5 things compost benefits:

Improves Soil Health Compost enhances soil structure, moisture retention, and fertility, making it easier to grow plants. 


Reduces Waste Composting diverts organic waste from landfills, reducing methane emissions and lowering your overall waste & carbon footprint. 


Nutrient-Rich Compost provides essential nutrients like nitrogen, phosphorus, and potassium to plants, reducing the need for synthetic fertilizers.


Supports Microbial Activity Compost introduces beneficial microorganisms to the soil, which helps to break down organic matter and improve overall plant health.


Reduces Soil Erosion By improving soil structure, compost helps to prevent erosion and supports healthy root systems.

What is the composting process?

Composting takes a bit of time to process and requires some effort. But the endless result is definitely worth it! Here are 5 steps of the basic composting process:

Collect organic materials, including kitchen scraps, yard waste, and other biodegradable materials.

Layer these materials in a compost bin or pile, alternating between green and brown materials to maintain a balanced carbon-to-nitrogen ratio.

Decomposition will begin to happen as time goes by. Microorganisms, worms, and insects are responsible for breaking down the organic matter into smaller and smaller pieces. This process generates heat, which further aids in breaking down the materials.

Turning the compost pile periodically helps to aerate it, ensuring that oxygen reaches all parts of the pile and speeding up the decomposition process.

Matured soil happens after several weeks to months, depending on conditions, the composting process slows down, and the soil begins to turn dark. This is when the compost is considered mature and is ready for use.

What is compost used for?

I consider compost as the "Golden Soil" because of its nutrient rich components and because you can use it for any gardening project. 

Here are 4 main uses for compost:  

Gardening  Compost is commonly used in gardens to enrich the soil and support plant growth, as well as for potting plants and flowers for inside the home. 


Agriculture  Farmers use compost to improve crop yields and maintain healthy soil.


Landscaping  Compost is used in landscaping projects to improve soil quality and support the growth of trees, shrubs, and lawns.


Erosion Control  Compost can be applied to areas prone to erosion to help stabilize the soil and prevent runoff.

How to Compost Outdoors

Composting at home in the outdoors is a great way to reduce waste, enrich your soil, and promote sustainability. 

Here’s a step-by-step guide to help you get started with outdoor composting:

Step 1: Choose a Composting Method

Decide on the type of composting that suits your needs and space. Common outdoor composting methods include:

Compost Bin: A contained space (usually a plastic or wooden bin) to manage compost neatly.

Compost Pile: An open pile that allows easy access and can be adjusted in size.

Compost Tumbler: A rotating barrel that makes it easy to mix the compost and speeds up decomposition.

Step 2: Select a Location

Pick a spot in your yard or garden for your compost bin or pile:

Partial Sunlight: A location with partial sunlight helps to keep the compost warm without drying it out too much.

Good Drainage: Make sure the spot has good drainage to prevent waterlogging.

Easy Access: Choose a place that is easy to reach for adding materials and turning the compost.

Step 3: Gather Materials

You need a good balance of "green" and "brown" materials to create a healthy compost mix. Aim for a 2:1 ratio of browns to greens.

Green Materials (Nitrogen-rich): Fruit and vegetable scraps, coffee grounds, grass clippings, tea bags, and fresh leaves.

Brown Materials (Carbon-rich): Dry leaves, straw, wood chips, shredded paper, cardboard, and sawdust.

Optional: Soil is a good element to add to your compost bin. It contains microorganisms that activate the decomposing process. Although it is not necessary to  begin composting, it will help process your compost quickly. 

Here are a few beginner composting soils that can help your compost bin flourish!

Step 4: Start Layering

Begin adding materials to your compost bin or pile:

First Layer (Browns): Start with a 4-6 inch layer of brown materials, like dry leaves or straw, and ~1 inch of soil or previously made compost, to provide aeration and drainage.

Second Layer (Greens): Add a 2-3 inch layer of green materials, such as fruit and vegetable scraps or grass clippings.

Alternate Layers: Continue layering browns and greens in alternating layers. Ensure that each green layer is covered with browns to reduce odors and deter pests.

Step 5: Maintain Moisture Levels

Compost should be as moist as a wrung-out sponge:

Add Water: If the pile is too dry, sprinkle it with water to moisten it.

Cover if Necessary: If your area experiences heavy rainfall, cover your compost to prevent it from becoming too wet.

Step 6: Turn the Compost

Turn your compost pile every 2-4 weeks using a pitchfork or shovel to aerate it:

Mixing: This helps to mix greens and browns, speeds up decomposition, and prevents odor.

Oxygenation: Aeration is crucial because composting is an aerobic process (requiring oxygen).

Step 7: Monitor and Troubleshoot

Regularly check the compost pile for:

Heat: A hot pile (between 120-160°F) indicates active decomposition.

Odor: A healthy compost pile should smell earthy. Foul odors suggest a lack of oxygen or excess green materials; add more browns and turn the pile.

Moisture: If the compost is too dry, add water. If too wet, add more brown materials.

Step 8: Harvest the Finished Compost

After 3-6 months (depending on conditions and materials), the compost should be dark, crumbly, and have an earthy smell:

Separate the Compost: Use a screen or sieve to filter out large, undecomposed pieces that can go back into the pile.

Use in Garden or Yard: Apply the finished compost to your garden beds, potted plants, or lawn as a nutrient-rich soil amendment.

Tips for Successful Composting:

Avoid Adding: Meat, dairy products, oily foods, pet waste, diseased plants, and chemically treated wood as they can attract pests and introduce pathogens.

Chop Large Pieces: Cutting up larger pieces of organic material speeds up the decomposition process.

Balance the Greens and Browns: Keeping the right balance of green and brown materials ensures a healthy composting process.

By following these steps, you'll be able to create nutrient-rich compost at home, reduce waste, and improve the health of your garden or landscape.

Compost bins are perfect for transfering your kitchen food scraps to your compost pile! Here are our favorite and stylish compost bins:

How to Compost Indoors

Composting indoors is a great way to recycle organic waste, even if you don't have outdoor space. Indoor composting is perfect for those living in apartments or homes without yards! 

Here’s a step-by-step guide to help you start composting indoors:

Step 1: Choose a Composting Method

There are several methods for indoor composting. You can choose one that suits your space and lifestyle:

Worm Composting (Vermicomposting): Using worms to break down food scraps. This method is odor-free and highly efficient.

Bokashi Composting: An anaerobic process using beneficial microbes to ferment kitchen waste in a sealed bucket. This method is compact and quick.

Compost Bin or Pail: A traditional compost bin modified for indoor use. These bins usually have a carbon filter to reduce odors.

Step 2: Select a Composting Container

Depending on the method chosen, you will need a specific container:

For Vermicomposting: A worm bin with small holes for ventilation and drainage. You can purchase one or make your own using a plastic storage bin.

For Bokashi: A specialized Bokashi bucket with an airtight lid and a spigot to drain liquid.

For Indoor Compost Bin: A small, lidded compost bin with a charcoal filter to control odors.

Step 3: Choose a Location

Find the right spot for your compost container:

Accessible: Place it in a convenient location, such as under the kitchen sink, in a pantry, or on a balcony.

Temperature Control: Avoid placing it in direct sunlight or areas with extreme temperatures. Room temperature (60-80°F) is ideal for composting.

Step 4: Gather Composting Materials

You’ll need a mix of "green" and "brown" materials for a healthy compost:

Green Materials Nitrogen-rich: Fruit and vegetable scraps, coffee grounds, tea bags, and crushed eggshells.

Brown Materials Carbon-rich: Shredded newspaper, cardboard, dry leaves, and paper towels (not used with chemicals or wax coating).

Step 5: Set Up the Compost Bin

Depending on your chosen method, set up the bin accordingly:

For Vermicomposting:

Prepare the Bin: Drill small holes in the sides and bottom of the bin for ventilation and drainage if your bin does not already have them. 

Add Bedding: Start with a 3-4 inch layer of damp, shredded newspaper, cardboard, or coconut coir as bedding.

Add Worms: Add red wiggler worms (Eisenia fetida), which are ideal for composting.

Add Food Scraps: Bury food scraps in the bedding, covering them well to avoid attracting pests.

For Bokashi Composting:

Prepare the Bucket: Ensure it’s clean and has a layer of Bokashi bran at the bottom.

Add Food Scraps: Add food scraps in small batches, pressing them down to remove air pockets.

Sprinkle Bokashi Bran: Each time you add food scraps, sprinkle a handful of Bokashi bran to aid fermentation.

Seal the Lid: Close the lid tightly after each addition to maintain an anaerobic environment.

For Indoor Compost Bin:

Layering: Start with a layer of shredded newspaper or cardboard at the bottom for absorption.

Add Food Scraps: Add a layer of food scraps, then cover with a layer of browns (newspaper or cardboard).

Alternate Layers: Continue to alternate green and brown layers, making sure to cover greens to reduce odors.

Step 6: Maintain the Compost Bin

Regular maintenance will ensure a successful composting process:

For Vermicomposting:

Feed the Worms: Add small amounts of food regularly (about once a week), burying the scraps.

Keep Moist: Ensure the bedding remains damp but not soggy.

Harvest Worm Castings: After 3-4 months, the worm castings (finished compost) can be harvested.

For Bokashi Composting:

Drain Liquid ("Bokashi Tea"): Use the spigot to drain liquid every few days. Dilute this liquid and use it as a fertilizer for plants.

Fermentation Time: Once the bucket is full, let it sit for 2 weeks to complete the fermentation process.

For Indoor Compost Bin:

Mix Regularly: Stir or shake the compost once a week to aerate it.

Monitor Moisture and Odor: Keep the compost moist but not wet. If there is an odor, add more brown materials.

Step 7: Harvest and Use the Compost

After several weeks to months (depending on the method), the compost will be ready for use:

Vermicomposting: Harvest worm castings from one side of the bin, leaving the worms in the other.

Bokashi Composting: Bury the fermented material in soil to complete decomposition or add it to a traditional compost pile.

Indoor Compost Bin: The compost will turn dark and crumbly when ready. Use it to enrich indoor potted plants, garden beds, or planters.

Tips for Successful Indoor Composting:

Avoid Adding Meat, Dairy, and Greasy Foods: These can create unpleasant odors and attract pests.

Chop Up Food Scraps: Smaller pieces decompose faster, making the process more efficient.

Monitor Conditions: Check moisture levels and adjust as needed to prevent issues like foul odors or mold growth.

By following these steps, you can create a sustainable composting system indoors and recycle organic waste, even without outdoor space.

Composting is an eco-friendly practice that helps close the nutrient loop, turning waste into a valuable resource for the environment.
