The Art of Composting: From Kitchen Scraps to Garden Soil

Composting is a time-honoured practice that has gained popularity as people become more conscious of their environmental impact. It’s a simple yet powerful way to minimise waste, enrich the soil, and create a sustainable cycle of nutrients.


Whether you have a sprawling garden or a small balcony, composting can be incorporated into your daily routine, no matter how limited your gardening space may be. Therefore, let’s explore the art of composting—from the humble beginnings of kitchen scraps and oft-overlooked “ugly produce” to the transformation of nutrient-rich garden soil.

The Fundamentals of Composting


Composting is a natural and eco-friendly process that entails the gradual breakdown of organic matter like residual fruits and vegetables, fallen leaves, grass clippings, and even used coffee grounds. This decomposition process is facilitated by a diverse community of microorganisms, encompassing bacteria, fungi, and worms, actively transforming these materials into fertile soil teeming with nutrients.


To start composting, you will require a suitable container or compost pile, a balanced mixture of green and brown materials, ample moisture, and sufficient airflow. By adhering to these fundamental elements, you can set the stage for successful composting while nurturing a sustainable cycle of organic waste transformation.

Getting Started: Setting Up Your Compost Bin


The first step of composting begins with the crucial task of setting up your compost bin. This can be as simple as a designated area in your garden or a purpose-built container for those with limited space. Choose a location that basks in ample sunlight and is conveniently accessible for the effortless addition and turning of compost. Additionally, ensure that the bin boasts sufficient size to accommodate your household’s waste, while allowing ample room for optimal aeration and decomposition.


The Ingredients: What to Compost


Composting is all about finding the right balance among its ingredients. Broadly speaking, compostable materials can be categorised into two groups: greens and browns. The greens encompass kitchen scraps like fruit and vegetable peelings, coffee grounds, and tea leaves, all providing valuable nitrogen necessary for the proliferation of microorganisms responsible for decomposition. Conversely, browns consist of carbon-rich materials such as dried leaves, wood chips, straw, and newspaper, which serve as an energy source for these microorganisms while helping maintain an optimal carbon-to-nitrogen ratio.


It’s essential to remember that certain items should be avoided in the composting process. Meat, dairy products, oily foods, and pet waste should be kept at bay, as they can attract pests and impede decomposition. Furthermore, exercise caution when adding weeds or plants that have produced seeds, as the heat generated during composting might not reach sufficient levels to eradicate the seeds entirely.


Choosing the Right Composting Method


Depending on your available space and preference, there are several composting methods to consider. 


  • Vermicomposting: Vermicomposting is a great option if you’re inclined towards a smaller-scale composting method or have limited space. It involves using worms, specifically red wrigglers or Eisenia fetida, to efficiently break down your organic waste.

    Start by getting a worm bin or constructing one using a container with adequate air holes. Add bedding material, such as shredded newspaper or cardboard, and introduce your worms into the bin. Then, begin feeding them with kitchen scraps like fruit and vegetable peels, tea bags, and coffee grounds while avoiding meat, dairy, oily foods, or citrus fruits.

    As the worms consume organic waste, they produce nutrient-rich worm castings, which serve as valuable compost. Remember to maintain the bin’s moisture level and strike a proper balance between food and bedding to ensure the contentment and productivity of your worms.


  • Bokashi Composting: Originating from Japan, Bokashi composting is a fermentation-based method that accommodates a wider range of materials, including meat, dairy, and cooked food scraps. This technique utilises specialised bokashi bran, which contains beneficial microorganisms that facilitate the fermentation process.

    To begin, layer your organic waste within a bokashi bucket, generously sprinkling a handful of the bran between each layer. As you go, gently press down on the waste to eliminate excess air and create a tight seal on the bucket, maintaining an anaerobic environment since fermentation occurs without oxygen. 

    The waste will undergo fermentation over the course of a few weeks. Once the fermentation process is complete, you’ll have a few viable choices. One option is to gently bury the fermented waste in your garden, enabling it to undergo further decomposition and contribute to the enrichment of the soil. Another possibility is to transfer the fermented waste to a compost pile, where it will continue to break down over time, ultimately transforming into valuable compost teeming with nutrients.



Regardless of the composting approach you use, it’s essential to maintain a delicate balance between green (nitrogen-rich) and brown (carbon-rich) materials. Additionally, ensure that the compost remains adequately moist without becoming overly saturated, and make it a habit to regularly turn or mix the pile.


The Art of Layering: Building the Perfect Compost Pile


Creating the perfect compost pile is like crafting a work of art. Begin by layering your compostable materials with a discerning eye. Lay down a foundation of browns, forming a sturdy base for your masterpiece, followed by a layer of greens. Continue this rhythmic alternation between browns and greens, taking care to break down larger pieces into smaller fragments to expedite the decomposition process. Strive for a balance between these two material types, aiming for an optimal ratio of 3 parts brown to 1 part green.


To ensure proper aeration, introduce occasional layers of twigs or wood chips into the mix, delicately weaving them to create air pockets within the pile. This allows vital oxygen to reach the diligent microorganisms and prevents the pile from succumbing to compaction. Nourish your creation with periodic watering, ensuring a moisture level akin to that of a damp sponge—neither excessively wet nor desiccated. Remember, composting is a microbial activity, and the harmonious interplay of moisture is essential for the thriving of these microscopic artists!


Patience and Maintenance: Tending to Your Compost


Composting, a marvel of nature, demands both patience and consistent care. As the weeks gracefully unfold, the microorganisms will work their magic, breaking down the organic matter into rich, dark compost.


To aid the process, gently turn the compost pile at regular intervals, employing a pitchfork or a compost aerator as your tool of choice. This act of turning blends the materials harmoniously, while generously infusing the microorganisms with the vital oxygen they crave. Aim to perform this turning ritual every few weeks or whenever the temperature begins to rise, thwarting the onset of an anaerobic environment.


Vigilantly monitor the moisture levels within your compost pile. If the pile appears too dry, imbue it with a sprinkle of water. Conversely, if excess moisture saturates the pile, graciously intermingle dry browns to absorb the extra liquid. Striking the ideal moisture balance ensures the thriving of a robust composting habitat, ripe with vitality and abundance.


Harvesting Your “Black Gold”


After several months of tender care, you will start to see the transformation of your compost pile as it matures into dark, crumbly soil. This remarkable concoction, affectionately known as “black gold,” is a valuable resource for your garden.


Use it to enrich the soil in your flower beds, vegetable patches, or potted plants. It will enhance soil structure, imbue it with exceptional moisture retention capabilities, and provide a cornucopia of vital nutrients, promoting healthy plant growth within your beloved plants.
