Building a successful backyard compost pile is easier than you think. To start, choose a location with good airflow and accessibility, ideally near a water source.
Brown materials like dried leaves and shredded newspaper provide carbon-rich nutrients for your compost pile, while green materials like food scraps and grass clippings provide nitrogen-rich nutrients.
Aim for a mix of 2/3 brown materials and 1/3 green materials in your compost pile. This balance will help create a thriving ecosystem.
Regular turning of your compost pile is essential to speed up the decomposition process and prevent pests and odors.
Building the Pile
To start building your compost pile, you'll need to create a foundation that allows for good airflow and drainage. Add 6-12 inches of stalky, course material at the bottom of the bin.
Next, create a thick nest of brown material inside the bin. This can be made up of dry, brittle materials like leaves, straw, newspaper, and wood chips.
Brown layers should be two or three times thicker than green layers, so don't be shy about adding plenty of browns to your pile.

Managing the Pile
Managing the Pile is a crucial part of creating nutrient-rich compost for your garden. To do this effectively, keep your compost pile at the right moisture level, as too much water can lead to bad odors and a lack of air circulation.
The ideal moisture level is like a wrung-out sponge, and you can achieve this by watering your compost as often as necessary. If your pile is too wet, turn it to aerate it and add some dry brown materials to balance it out.
To speed up decomposition, turn your pile at least once a year. Remove the outer layer of browns, and use a shovel or pitchfork to flip the remaining contents into a new bin. Alternatively, you can tumble or roll your bin to mix up the materials.
Here are some tips to keep in mind when managing your compost pile:
- Keep the pile at the right moisture level.
- Add dry brown materials if it's too wet.
- Turn the pile at least once a year.
- Use a shovel or pitchfork to mix up the materials.
By following these simple tips, you'll be well on your way to creating a thriving compost pile that will provide your garden with the nutrients it needs to grow strong and healthy.
Maintain Your Pile
A well-maintained compost pile is key to successful composting. Keep your compost pile at the right moisture level, as a bad odor often indicates it's too wet.
To achieve the perfect moisture level, aim for a consistency like a wrung-out sponge. If your pile lacks air circulation or is too wet, try turning it and/or adding dry, brown materials.
If your compost pile isn't heating up, it may need more nitrogen or "green" material. Adding grass clippings can help speed up the process.
Bury kitchen scraps at least 8 inches deep to discourage critters from visiting your pile. This simple step can save you from unwanted visitors.
Here are some general guidelines for maintaining your compost pile:
- Active compost piles heat to between 130° and 160° Fahrenheit.
- Turn the pile once or twice a month to speed decomposition and reduce odors.
- Keep the pile moist, but not soggy, by watering it periodically.
- A well-managed compost pile will be ready in two to four months in the warm season.
By following these tips, you'll be on your way to managing a healthy and thriving compost pile.
Three Chambered
Managing the Pile can be a challenge, but with the right tools and knowledge, it can be a breeze. A three-chambered composting bin is a great option for efficient composting.
It holds a considerable amount of compost, allowing for large quantities of food scraps and yard waste to be processed at once. This is especially helpful for households with multiple people or those who generate a lot of organic waste.
The three-chambered bin works like an assembly line, having three batches of compost in varying stages of decomposition. This process helps to speed up the composting time and ensures that the final product is rich in nutrients.
With a three-chambered bin, you can easily manage the composting process and maintain a balanced ecosystem.
What to Add/Not to Add
When composting, it's essential to know what to add and what to avoid. Here's a rundown of what you can and can't compost in your backyard bin.
You can compost a wide variety of organic materials, including coffee grounds, eggshells, faded flowers, fruit and vegetable scraps, and small amounts of wood ash and sawdust.
Fruit and vegetable scraps, coffee grounds, and fresh grass clippings are all great additions to your compost bin, as they provide nitrogen-rich "greens" that help speed up the decomposition process.
Shredded newspaper, cardboard, and dry grass clippings are excellent sources of carbon-rich "browns" that help balance out the greens and create a healthy compost pile.
However, there are some things you should avoid adding to your compost bin. Pet feces can transmit diseases, so it's best to keep them out of your compost pile.
Meat, bones, grease, whole eggs, and dairy products attract rodents and other animals, so it's best to keep them out of your compost bin as well.
Here's a list of items to avoid in your backyard compost bin:
- Bones don't compost quickly enough—they'll be there for years!
- Meat attracts nuisance animals, also known as vectors.
- Eggs attract vectors, but eggshells by themselves are okay, as they provide a slow-release source of calcium.
- Cheese and other dairy products attract vectors.
- Oils are okay in small quantities, such as the amount you'd consume in a meal, but pouring in greater amounts of oil will slow down decomposition in the pile.
- Excrement from dogs, cats, and other household pets can contain human pathogens—but a small amount of livestock manure is okay.
- “Compostable” products, such as plant-based plastics, are NOT designed for backyard composters.
Remember, maintaining a balance of green and brown materials in your compost bin is key to creating a healthy and thriving compost pile. Aim for a ratio of 1:2 greens to browns to get the breakdown process started and keep it going.
Troubleshooting and Maintenance
A compost pile can be a delicate balance of ingredients, and sometimes it can go wrong. If your compost pile isn't heating up, try adding more greens or larger volumes of browns and greens.
Too much moisture can be a problem, so make sure to add greens or water if it's too dry, and add browns or decrease greens if it's too wet.
Foul odors can be a sign that you need to add more browns to your pile. And if you're dealing with flies and other pests, try adding more browns and making sure no food is showing.
To maintain a healthy compost pile, keep it at the right moisture level. If it smells bad, it may lack air circulation or be too wet – try turning the pile and adding dry brown materials.
If your compost pile is not heating up, it may need more nitrogen or "green" material – add grass clippings to the pile.

Here are some common issues and their solutions:
To keep your compost pile active, turn it once or twice a month to help speed decomposition and reduce any foul odors. Continue to water it periodically to keep it moist but not soggy.
Using the Compost
Finished compost is a dark brown and crumbly material with no recognizable compostables left and no foul odors. It may take a year or longer to generate finished compost, depending on the materials added and how often the pile was turned.
Woody materials will take longer to break down, so be patient. Compost happens, and it's worth the wait.
You can use finished compost in several ways. Here are some examples:
- Mulch or "top dress" planted areas
- Amend to soil prior to planting
- As a component in potting media
To use the compost effectively, add about two inches of compost to new beds and about one inch of compost each year to existing beds.
Structures and Materials
To save space and speed up composting time, consider containing your compost in a structure. This is especially important in an urban setting where unenclosed compost piles can become unsightly.
A structure can help keep materials from blowing away and encourage faster and more thorough composting by creating higher temperatures near the center.
You can build a structure from materials like cement blocks, brick, wood, or woven wire fencing. Wood should be rot-resistant or pressure-treated with a wood preservative.
Smaller structures don't create enough heat, while larger ones may not allow enough air and water penetration. A good size is about 3 to 5 feet in each direction.
Here are some common materials to consider for your composting structure:
- Cement blocks
- Brick
- Wood (rot-resistant or pressure-treated)
- Woven wire fencing
- Welded wire
Choosing a System
Choosing a system for composting can be a bit overwhelming, but it's worth considering the options before you start.
There is no one right way to compost, and different methods have different costs and benefits.
An open pile is a common method that works well if you have some land and your proximity to neighbors is low.
Open piles tend to be managed less, and pests and foul odors can occur, so make sure you have a suitable location.

You can build your own bin from various materials, such as welded wire, wood pallets, chicken wire, cinder blocks, drums, and trash cans.
Welded wire bins are the most cost-effective option.
It's a good idea to choose a bin that is at least 3x3x3 feet in size to minimize the surface-to-volume ratio and improve heat retention during composting.
Cement Blocks and Bricks
Cement blocks and bricks can be used to build a composting bin, and it's a great option for those who want a more rustic look.
You can lay the cement blocks or bricks without mortar, leaving spaces between blocks to permit aeration. This will help keep your compost pile healthy and prevent it from getting too hot.
A three-sided, square or three-bin unit is a good design to consider when building a cement block and brick composting bin. This will give you a good balance between space and aeration.
If you have young children who like to play in the yard, you might want to think twice about using cement blocks or bricks for your compost bin. They can be unstable and might not be safe for little ones to be around.
Here are some tips for building a cement block and brick composting bin:
- Lay the cement blocks or bricks without mortar, leaving spaces between blocks to permit aeration.
- Build a three-sided, square or three-bin unit.
