Benefits of Organic Composting

Reduced waste in landfills

Organic composting plays a crucial role in reducing the amount of waste sent to landfills. By composting kitchen scraps, yard waste, and other organic materials, you are diverting them from ending up in landfill sites where they contribute to the generation of harmful methane gas. Instead, by composting these materials, you are giving them a second life as nutrient-rich soil amendment.

Improved soil fertility

One of the greatest benefits of organic composting is its ability to improve soil fertility. Compost is packed with essential nutrients such as nitrogen, phosphorus, and potassium, which are vital for plant growth. When you incorporate compost into your soil, it increases its organic matter content, enhances its water-holding capacity, and promotes the growth of beneficial microorganisms. All these factors contribute to creating a fertile soil environment that supports healthy plant growth.

Reduction in chemical fertilizer use

When you rely on organic compost to nourish your garden, you can significantly reduce the need for chemical fertilizers. Chemical fertilizers often contain harmful synthetic substances that can harm soil life, pollute water sources, and have negative effects on the environment. By using compost as a natural and sustainable alternative, you are providing your plants with the nutrients they need without the negative impacts of chemical fertilizers.

Enhanced plant growth

Organic composting results in improved plant growth. The nutrients present in compost, such as nitrogen, phosphorus, and potassium, are released slowly over time, providing a steady supply of nourishment for your plants. This steady release of nutrients promotes strong root development, lush foliage, vibrant blooms, and abundant harvests. Whether you have a small container garden or a sprawling vegetable plot, incorporating organic compost into your garden beds will undoubtedly boost the overall health and productivity of your plants.

Reduced carbon emissions

By engaging in organic composting, you are actively participating in the reduction of carbon emissions. When organic materials decompose in landfills, they produce methane gas, a potent greenhouse gas that contributes to climate change. Composting these organic materials instead allows them to break down in an oxygen-rich environment, preventing the release of methane gas. Through this simple act of composting, you are making a positive impact on the environment by mitigating greenhouse gas emissions.

Getting Started with Organic Composting

Understanding the basics of composting

Before you dive into the world of organic composting, it’s essential to understand the basics. Composting is the natural process of decomposition, where organic materials break down into humus-rich compost. It involves providing the ideal conditions for microorganisms, such as bacteria and fungi, to thrive and break down the organic matter. These microorganisms, along with earthworms and other decomposers, work together to transform your kitchen and yard waste into nutrient-dense compost.

Choosing the right composting method

There are several composting methods to choose from, depending on your space, time, and resources. Traditional composting, vermiculture (composting with worms), bokashi composting, trench composting, and compost tumblers are all effective methods. Each has its own advantages and considerations, so it’s important to choose one that suits your specific needs and constraints. Whether you have a small urban balcony or a spacious backyard, there’s a composting method that will work for you.

Selecting a suitable composting location

When choosing a composting location, it’s important to consider factors such as sunlight exposure, drainage, and accessibility. Most composting methods require a well-drained area that receives partial sunlight. This ensures that the compost pile remains moist but not waterlogged and allows the microorganisms to work their magic. Additionally, you’ll want to pick a spot that is easily accessible for adding organic materials and turning the compost as needed.

Gathering organic materials

To start your compost pile, gather a variety of organic materials from your kitchen, yard, and garden. Kitchen waste such as fruit and vegetable scraps, coffee grounds, and eggshells are excellent additions to your compost. Yard waste, including grass clippings, leaves, and weeds, can also be composted. Additionally, garden waste like plant trimmings, dead flowers, and small branches make great compost ingredients. You can even include paper products such as shredded newspaper, cardboard, and paper towels. Remember to avoid adding meat, dairy, oily foods, and pet waste to your compost pile, as these can attract pests and slow down the decomposition process.

Layering green and brown waste

To ensure proper decomposition, it’s important to layer your organic materials. Aim for a mix of green and brown waste. Green waste refers to nitrogen-rich materials like fresh grass clippings and kitchen scraps. Brown waste, on the other hand, refers to carbon-rich materials such as dried leaves and shredded newspaper. For optimal decomposition, alternate layers of green and brown waste, making sure to cover any fresh kitchen scraps with a layer of brown waste to prevent odors and pests.

Turning the compost pile

Periodically turning your compost pile is crucial to promote proper aeration and decomposition. Use a pitchfork or shovel to mix the outer layers into the center of the pile, ensuring that all the organic materials are exposed to oxygen. This helps prevent the compost from becoming anaerobic, which can result in unpleasant odors and slow the decomposition process. Aim to turn your compost every few weeks or whenever the pile becomes compacted. After turning, you may notice steam rising from the pile, indicating a healthy decomposition process.

Monitoring moisture and temperature

Keeping an eye on the moisture and temperature of your compost pile is essential for successful composting. The ideal moisture level is similar to that of a wrung-out sponge – moist but not waterlogged. If your compost is too dry, it may hinder decomposition. In contrast, if it’s too wet, it can become anaerobic and produce foul odors. To maintain the right moisture level, periodically sprinkle water over the compost pile during dry periods or cover it during heavy rain. Temperature-wise, compost should ideally reach between 120 and 150 degrees Fahrenheit during the active decomposition phase. This allows the organic matter to break down efficiently.

Dealing with common composting issues

While composting is a relatively straightforward process, there are common issues that may arise. Foul odors can indicate an imbalanced compost pile or excessive moisture. To remedy this, turn the pile and add more brown waste to promote better aeration. Pests, such as fruit flies and rodents, may also become attracted to your compost. Avoid adding meat, dairy, and oily foods to deter these pests. If the compost pile is not decomposing as expected, it may require more green waste or regular turning to ensure sufficient airflow. By troubleshooting and addressing these issues promptly, you can maintain a healthy and thriving compost pile.

Organic Materials for Composting

Kitchen waste: fruit and vegetable scraps, coffee grounds, eggshells

In the kitchen, you have various organic materials that make excellent additions to your compost pile. Fruit and vegetable scraps, including peels, cores, and seeds, can all go into the compost. Coffee grounds, whether from a French press or a coffee machine, are a valuable source of nitrogen. Crushed eggshells add calcium to the compost, contributing to the overall fertility of the soil.

Yard waste: grass clippings, leaves, weeds

Yard waste is another valuable resource for composting. Grass clippings are an excellent source of nitrogen and can provide a quick boost of nutrients to your compost pile. Fallen leaves are high in carbon and act as a natural source of insulation, helping maintain the compost’s temperature. Even weeds can be composted, but be cautious with weeds that have gone to seed to avoid spreading them throughout your garden.

When you’re working in your garden, there are plenty of opportunities to collect organic materials for composting. Plant trimmings, such as pruned branches or leaves, can be added to your compost pile. Dead flowers from bouquets or spent annuals can also be composted. Small branches that have fallen from trees can be chopped up or run through a chipper to create a valuable carbon-rich ingredient for your compost.

Paper products: shredded newspaper, cardboard, paper towels

Paper products are not only recyclable but also compostable. Shredded newspaper and cardboard make great sources of carbon that help balance the nitrogen-rich materials in your compost pile. Paper towels that have been used to clean up food scraps or excess moisture can also be composted. Avoid using glossy or heavily printed paper, as they may contain chemicals that are not beneficial for your compost or your garden.

Composting Methods

Traditional composting

Traditional composting, also known as backyard composting, is the most common method used by home gardeners. It involves creating a compost pile or bin where organic materials are layered and allowed to decompose naturally. This method relies on the activity of microorganisms, worms, and other decomposers to break down the organic matter into compost over time. With proper maintenance and a good balance of green and brown waste, traditional composting can yield nutrient-rich compost for your garden.


Vermicomposting, or composting with worms, is a popular method that involves using special composting worms, such as red wigglers, to break down organic materials. A worm bin is set up, and the worms consume the organic waste, producing nutrient-rich castings (worm poop) as an end product. Vermicomposting is an excellent option for those with limited space or who want to compost indoors. The resulting worm castings are highly beneficial for enriching soil and can be used as a top dressing or mixed into potting mixes.

Bokashi composting

Bokashi composting is a fermentation-based method that uses a special blend of beneficial microorganisms to break down organic materials. It involves layering organic waste in an airtight container and sprinkling it with the microorganism-rich bokashi bran. The sealed container allows anaerobic fermentation to take place, resulting in pickled organic matter. After the fermentation process, the bokashi material is typically buried in the soil or added to a traditional compost pile, where it continues to break down into nutrient-rich compost.

Trench composting

Trench composting involves digging a trench in your garden and burying organic waste directly into the soil. This method is convenient for gardeners who prefer a low-maintenance option and want to compost food scraps directly in their garden beds. Simply dig a trench approximately 12 to 18 inches deep, add your organic waste, cover it with soil, and allow it to break down over time. As the organic matter decomposes, nutrients are released directly into the soil, benefiting nearby plants.

Compost tumblers

Compost tumblers are enclosed containers that allow for easy and efficient composting. These containers are designed to be rotated, which accelerates the decomposition process by providing regular aeration and turning of the compost pile. Compost tumblers are particularly useful for gardeners with limited space or those who prefer a more contained and controlled composting method. By regularly turning the tumbler, you can produce fresh compost in a shorter amount of time compared to traditional composting methods.

Composting Dos and Don’ts
