By composting, we can make a positive impact on the environment while simultaneously reaping the benefits of healthier soil and more productive plants. Now that we understand the importance of composting, let’s delve into which materials can be composted to create nutrient-rich soil amendment.

What Can Be Composted

Composting is a versatile process that allows for the breakdown of a wide range of organic materials. To achieve a successful compost pile, it’s important to balance the ingredients and incorporate a mix of “greens” and “browns.

• Greens: Greens are materials that are rich in nitrogen, providing the necessary protein for microorganisms to break down organic matter. Common green materials include:
• Vegetable and fruit scraps
• Coffee grounds and filters
• Grass clippings (without herbicides)
• Green leaves and plant trimmings
• Tea bags (remove any metallic staples)
• Browns: Browns are high in carbon and help create airflow in the compost pile. They balance the high nitrogen content of greens and include:
• Dry leaves
• Shredded newspaper (avoid glossy paper)
• Cardboard (free of tape, stickers, and plastic)
• Straw or hay
• Wood chips or sawdust

It’s important to avoid composting items that can cause issues or contaminate the compost. These include:

• Meat, dairy, or greasy foods (they can attract pests and have a longer decomposition time)
• Animal waste
• Coal or charcoal ash
• Diseased plants
• Plastic, glass, or metal
• Weeds with seeds or invasive plant species
• Chemically-treated wood or sawdust

Remember that a successful compost pile requires both greens and browns and should be layered to promote proper decomposition. Aim for a ratio of roughly 3 parts browns to 1 part greens by volume. Additionally, it’s important to regularly turn the pile to provide oxygen and ensure an even breakdown of materials.

Now that we know what can be composted, let’s dive into the do’s and don’ts of composting to ensure optimal results for your compost pile.

Greens

Greens, also known as nitrogen-rich materials, are a vital component of successful composting. They provide essential nutrients and moisture to help break down organic matter effectively. Here are some common examples of greens that can be added to your compost pile:

• Vegetable and fruit scraps: Include peels, cores, and scraps from a variety of fruits and vegetables. Avoid adding any spoiled or moldy produce, as it can attract pests.
• Coffee grounds and filters: Used coffee grounds are an excellent source of nitrogen and can be added to your compost. Make sure to remove any plastic or metal components from coffee filters before composting.
• Grass clippings (without herbicides): Fresh grass clippings are high in nitrogen and add moisture to the compost pile. However, be cautious if you have used herbicides on your lawn, as these chemicals can negatively affect the composting process.
• Green leaves and plant trimmings: Any green plant material, such as leaves, small branches, or plant trimmings, can be added to the compost pile. Chop them into small pieces to speed up the decomposition process.
• Tea bags: Used tea bags can be added to the compost pile, but be sure to remove any metallic staples. Tea leaves are a great source of nitrogen and can enrich the nutrient content of your compost.

When adding greens to your compost pile, it’s important to maintain a balance with “browns” – carbon-rich materials – to facilitate proper decomposition. Too much nitrogen-rich material can result in a smelly, slimy compost pile. Aim for a ratio of approximately 1 part greens to 3 parts browns to maintain a healthy composting environment.

To enhance the decomposition process, chop or shred your green materials into smaller pieces. This increases the surface area, allowing microorganisms to break them down more efficiently. It’s also important to layer the greens within the compost pile rather than placing them in a single clump. This helps to ensure even distribution and proper oxygen flow.

Remember to water the compost pile periodically, especially if the greens added are dry. This helps to maintain the optimal moisture level for decomposition. Too much or too little moisture can hinder the composting process, so aim for a moist but not saturated consistency.

By including a healthy mix of greens while composting, you are not only diverting waste from landfills but also creating nutrient-rich compost that will nourish your plants and promote a flourishing garden.

Browns

Browns, also known as carbon-rich materials, are an essential component of composting. They provide structure, absorb moisture, and create airflow within the compost pile. Incorporating a balanced mix of browns along with greens helps create a healthy and productive composting process. Let’s explore some common examples of browns:

• Dry leaves: Fallen leaves are a readily available source of carbon. Collect them in the fall and use them throughout the year for your compost pile. Shred or break them into smaller pieces to speed up decomposition.
• Shredded newspaper: Newspaper can be an excellent source of carbon. Tear it into small strips or shred it before adding it to the compost pile. Avoid using glossy or colored sections, as they may contain chemicals that are harmful to the soil and plants.
• Cardboard: Unprinted and untreated cardboard, such as cardboard boxes, can be a great source of carbon. Tear the cardboard into small pieces and add it to the compost pile, making sure to remove any tape, stickers, or plastic materials.
• Straw or hay: Straw or hay can be used as a brown material in composting. These materials provide structure and help create air pockets within the pile. Make sure they are free of pesticides or herbicides that could potentially harm your plants.
• Wood chips or sawdust: Small amounts of untreated wood chips or sawdust can be added to the compost pile. However, avoid using large quantities as wood takes longer to break down and can affect the carbon-to-nitrogen ratio.

While adding browns to the compost pile, remember to maintain a proper balance with greens. Aim for a ratio of roughly 3 parts browns to 1 part greens by volume. This ratio provides optimum conditions for microorganisms to break down the organic matter effectively.

Layering the browns throughout the compost pile helps create a well-mixed and well-aerated environment. Avoid placing a thick layer of browns on top or bottom of the pile, as it may hinder proper airflow and slow down decomposition. Instead, alternate layers of greens and browns to ensure even distribution of materials.

It’s important to note that browns decompose at a slower rate compared to greens. Patience is key! It may take a bit longer for the browns to break down, but they provide long-term benefits to the soil structure and nutrient composition.

By including a balanced mix of browns in your composting process, you are enhancing the decomposition rate, improving the quality of your compost, and contributing to a healthier and more sustainable gardening practice.

1. Gather materials:

Collect a mix of greens (nitrogen-rich materials) and browns (carbon-rich materials) to create a balanced compost pile. Remember to include a variety of organic waste, such as kitchen scraps, yard trimmings, and dry leaves, to supply the necessary nutrients for microorganisms.

2. Prepare the compost pile or bin:

Choose an appropriate location for your compost pile or bin. It should be well-drained and receive partial sunlight. If using a bin, ensure it has proper aeration and drainage. Layer the greens and browns in the compost pile, starting with a layer of browns, followed by greens, and continue this alternating pattern. Moisten the pile until it feels like a damp sponge.

3. Turn the compost pile:

Regularly turning the compost pile is essential to provide oxygen and aid decomposition. Use a pitchfork or shovel to mix the materials thoroughly. Turning the pile once every few weeks helps distribute heat, moisture, and microbes evenly, promoting faster breakdown.

4. Maintain moisture levels:

Ensure that the compost pile remains moist but not overly saturated. Water the pile regularly, especially during dry periods, to keep the materials adequately damp. A dry compost pile slows down decomposition, while excessive moisture can lead to a smelly, anaerobic environment. Adjust the moisture level as needed to provide optimal conditions for microbial activity.

5. Monitor and adjust the compost pile:

Regularly monitor the compost pile for temperature, smell, and moisture. As the decomposition process progresses, the pile will generate heat, reaching temperatures between 110-160°F (43-71°C). If the pile becomes too hot or starts to emit a foul odor, it may indicate an imbalance of materials or insufficient aeration. Adjust the compost pile by adding more browns or turning the pile more frequently to correct the conditions.

6. Wait for the compost to mature:

Composting takes time, and the duration can vary depending on factors such as the materials used, environmental conditions, and management practices. Generally, composting can take anywhere from a few months to a year to reach maturity. The finished compost will be dark, crumbly, and have a pleasant earthy smell.

7. Use the compost:

Once the compost has matured, it is ready to be used in your garden. Apply the compost as a top dressing in garden beds, mix it with potting soil for container plants, or use it as a nutrient-rich mulch. The compost will improve soil structure, fertility, and water-holding capacity, benefiting your plants’ overall health and productivity.

By following the composting process, you can turn organic waste into valuable compost, reducing landfill waste and nourishing your garden in an environmentally friendly way. Patience and proper management will yield quality compost for years to come.

Turning the pile every few weeks using a pitchfork or shovel accelerates the decomposition process and prevents the formation of anaerobic conditions. This promotes the growth of beneficial microorganisms and ensures the breakdown of organic matter.

2. Monitoring moisture levels:

Proper moisture is crucial for composting. The compost pile should be damp, similar to a wrung-out sponge. If the pile becomes too dry, decomposition slows down. Conversely, if it is too wet, it may become compacted and emit a foul odor. Regularly check the moisture levels and adjust by adding water or dry materials (such as dry leaves) to maintain the ideal moisture balance.

3. Adding additional materials:

As you accumulate kitchen scraps and yard waste, regularly add them to the compost bin. Continuously incorporating a mixture of greens (nitrogen-rich materials) and browns (carbon-rich materials) maintains the ideal carbon-to-nitrogen ratio and ensures a balanced composting environment. Aim for a mix of roughly 3 parts browns to 1 part greens to promote efficient decomposition.

4. Managing pests:

Pests such as fruit flies, ants, or rodents may be attracted to your compost bin. To deter these pests, bury food scraps beneath a layer of browns or cover the compost pile with a breathable material such as a mesh screen. Avoid adding meat, dairy, or greasy foods that are more likely to attract pests. If you encounter persistent pest issues, consider placing a hardware cloth at the bottom of your compost bin to prevent rodents from accessing it.

5. Controlling odor:

An unpleasant odor in your compost bin can indicate an imbalance of materials or inadequate aeration. Mix in browns such as dry leaves or shredded newspaper to absorb excess moisture and help combat odor. Additionally, make sure the pile is properly turned and aerated to promote proper decomposition and reduce the risk of foul smells.

6. Harvesting the compost:

Once the compost has fully decomposed and reached a dark, crumbly consistency, it is ready to be harvested. You can do this by either removing the compost from the bottom of the bin or using a compost tumbler by rotating it to empty the fully processed compost. The remaining compost can be used in your garden to nourish plants and improve soil fertility.

By maintaining your compost bin properly, you create an optimal environment for decomposition, limit potential issues, and ensure the production of high-quality compost. Regular turning, monitoring moisture levels, and managing pests will help you achieve successful composting results and contribute to a healthy and sustainable garden.
