Getting Started with Composting: Basics You Need to Know
To create high-quality compost, you need to understand which materials are suitable. Composting involves both “green” and “brown” materials.
Green Materials
Green materials, often rich in nitrogen, include:
- Vegetable scraps
- Fruit peels
- Coffee grounds
- Grass clippings
These materials are typically moist and fresh, providing essential nutrients that support the composting process.
Brown Materials
Brown materials, which are high in carbon, encompass:
- Dry leaves
- Straw or hay
- Shredded paper
- Cardboard
These materials are dryer and serve as a carbon source, balancing the nitrogen-rich greens and encouraging the decomposition process.
What to Use for Garden Compost: The Ultimate List
When creating a compost pile, it’s crucial to balance your greens and browns effectively. Here is an extensive list highlighting what you can use for your garden compost.
1. Kitchen Scraps
Utilizing kitchen scraps is one of the easiest ways to add organic matter to your compost. Here’s what you can include:

- Coffee grounds (and filters)
While kitchen scraps are great, remember to avoid meat, dairy, and oily foods, as they can attract pests and create unpleasant odors.
2. Yard Waste
Yard waste is plentiful and provides an excellent opportunity for composting. You can add:
- Lawn clippings (avoid using treated grass)
- Leaves (shredded for faster decomposition)
- Small branches and twigs (chopped into smaller pieces)
- Flowers and plant trimmings
Including a variety of yard waste not only boosts nutrient content but also adds bulk to your compost.
3. Garden Plants and Weeds
Adding spent plants and weeds to compost is beneficial:
- Pull out old or diseased plants and add them to the compost.
- Add weeds that have not produced seeds (to prevent them from germinating).
4. Hay and Straw
Hay and straw are excellent additions that contribute nitrogen and carbon. They also help to aerate the compost pile, which is vital for microbial activity. Make sure to choose untreated hay to avoid chemical contamination.
5. Manure
Animal manure from herbivores, such as cows, horses, rabbits, and chickens, can be a powerful addition to compost. Ensure that the manure is aged or well-composted, as fresh manure may contain pathogens that can harm plants. Be cautious with pet waste, particularly from carnivorous animals, as it can contain harmful bacteria.
6. Wood Chips and Sawdust
Wood chips and sawdust can create better structure in your compost. They provide carbon and encourage aeration. However, they should be used sparingly and mixed well with greens to avoid compacting.
What Not to Use in Garden Compost
While there are numerous materials that are perfect for composting, some items should be strictly avoided:

4. Non-Biodegradable Materials
Plastic, glass, and metal should never be included in compost as they do not break down and can harm the environment.
5. Certain Yard Waste
Be wary of invasive weeds and canes from plants like bamboo or Japanese knotweed, as these can survive composting and sprout in your garden.
The Best Practices for Creating Compost
Creating compost is more than just tossing your kitchen scraps and yard waste into a heap. Here are some best practices to maximize the efficiency of your composting efforts.
1. Maintain a Balance of Greens and Browns
Aim for a ratio of approximately 30% green materials to 70% brown materials. This balance will ensure that you get the right amount of nitrogen and carbon to support decomposition.
2. Turn Your Compost Regularly
To aerate the compost and speed up the decomposition process, turn your pile every few weeks with a pitchfork or compost turner. This practice introduces oxygen and helps maintain microbial activity.
3. Monitor Moisture Levels
Your compost should be moist but not saturated. If your pile is dry, add water. If it is too wet, mix in more dry materials like shredded newspaper or straw to absorb excess moisture.
4. Use a Compost Thermometer
Using a compost thermometer can help you monitor the temperature of your compost. A healthy compost pile should reach between 130°F to 160°F in temperature, which is ideal for killing weeds and pathogens.
Encouraging Microbial Activity
Microbes play a crucial role in breaking down materials in your compost. You can encourage their presence by properly layering your pile and introducing compost activators such as:
- A handful of garden soil (teeming with beneficial microbes)
- Finished compost from a previous batch
- A compost starter or activator (available in garden centers)
These methods can help stimulate the composting process and promote healthy microbial activity.
Using Finished Compost: Maximizing Your Garden’s Potential
After several months, your compost will break down into a dark, crumbly substance. This is your finished compost which should have a pleasant earthy smell.
You can use the compost in various ways to support your garden:
1. Soil Amendment
Add compost to your garden soil before planting to improve its structure, aeration, and nutrient content.
2. Mulch
Spread a layer of finished compost around your plants. It will help retain moisture and suppress weeds while slowly nourishing your plants.
3. Compost Tea
Soak finished compost in water for a few days to create compost tea, a nutrient-rich solution you can use as a fertilizer.
4. Top Dressing
After the growing season, apply a layer of compost on top of your garden beds to protect the soil over winter and prepare it for the next planting season.

What materials can I compost in my garden?
You can compost a wide variety of organic materials that fall into two main categories: green materials and brown materials. Green materials include kitchen scraps like vegetable peels, coffee grounds, and fruit waste, as well as grass clippings and fresh leaves. Brown materials encompass dried leaves, straw, shredded paper, and cardboard. It’s beneficial to maintain a balance of green and brown materials, ideally in a ratio of about one part green to three parts brown, to create a healthy compost mixture.
Avoid composting meat, dairy products, and oils as these can attract pests and create odors. Additionally, be cautious with composting diseased plants or weeds that have gone to seed, as they could propagate in your garden once the compost is spread. Instead, focus on carbon-rich and nitrogen-rich materials to create nutrient-dense compost that will benefit your garden.
How do I create a compost pile?
Creating a compost pile involves several straightforward steps. Start by choosing a designated area in your garden that is easily accessible but out of direct sunlight. Begin layering your compost materials, starting with coarse materials like straw or small branches at the bottom to help with aeration. Alternate between layers of green and brown materials, ensuring that you’re maintaining the right balance for optimal decomposition.
As you build your pile, occasional turning is essential to aerate the compost and speed up the decomposition process. Regularly monitor the moisture level, aiming for a consistency similar to a damp sponge. You can check the temperature of the pile; if it isn’t heating up after a few weeks, it may need more green materials or moisture. With patience and proper care, your compost will break down into rich, dark soil that can nourish your garden.
How long does it take for compost to mature?
The time it takes for compost to mature can vary widely depending on several factors, including the materials used, the size of the pile, and environmental conditions. Typically, compost can take anywhere from three months to a year to fully decompose into nutrient-rich, dark soil. Aeration, moisture, and temperature all play significant roles in accelerating the composting process. The more actively you manage your compost pile, the faster you can expect it to mature.
If you’re looking to speed up the process, regularly turning the pile can help introduce more oxygen, which promotes microbial activity. Using smaller pieces of kitchen scraps and yard waste will also create more surface area for microbes to work on. Remember that patience is key; even if the compost takes longer, it can still yield excellent results for your garden.
Can I use compost for potted plants?
Yes, compost is an excellent addition to potted plants, as it provides vital nutrients that promote healthy growth. When using compost in pots, it’s often best to mix it with potting soil to ensure proper drainage and aeration, as pure compost can be quite dense. A common ratio is about one part compost to three parts potting soil, which will provide your plants with the nutrients they need while maintaining a light texture.
When adding compost to your potted plants, be mindful not to overfeed them, as too much nitrogen can lead to excessive leaf growth at the expense of flowers or fruits. Regularly monitor the moisture levels in the pots as compost tends to retain water. Providing a steady supply of nutrients from your compost will benefit your plants throughout their growing season, leading to vibrant and healthy growth.
What are the signs of finished compost?
Finished compost has several distinct characteristics that indicate it is ready to be used in your garden. Firstly, it should have a dark brown or black color and a crumbly texture, resembling rich soil. The original materials used for composting should no longer be recognizable; they will have fully broken down into a fine, cohesive mix. Additionally, the compost should have an earthy smell, devoid of any foul or rotten odors.
Another sign of finished compost is the presence of heat. When decomposition is complete, the pile will have cooled significantly from its earlier temperatures. At this stage, you can also perform a simple jar test: take a handful of your compost and wet it slightly. If no water pools at the bottom of the jar, it indicates a good balance of moisture and structure, suggesting the compost is ready for use in your garden beds, potted plants, or as a top dressing for lawns.
Is composting environmentally friendly?
Composting is indeed a highly environmentally friendly practice that significantly reduces waste destined for landfills. When organic materials are thrown away, they break down anaerobically in landfills, producing methane, a potent greenhouse gas that contributes to climate change. By composting these materials instead, you not only divert waste from landfills but also create a valuable resource that enriches soil health and protects our ecosystem.
Furthermore, using compost in gardens and landscapes reduces the need for chemical fertilizers, which can leach into waterways and harm aquatic ecosystems. Compost enriches soil structure, boosts its ability to retain water, and fosters biodiversity among soil organisms. By embracing composting, you are contributing to a cycle of recycling that benefits your garden and helps protect the planet for future generations.
