Composting is a simple way to turn everyday kitchen and yard waste into a useful soil amendment. Instead of sending food scraps and leaves to the landfill, you can allow them to break down naturally and create compost for gardens, flower beds, containers, and lawns.
Starting a compost pile does not require much space, money, or experience. With the right location, a balanced mix of materials, and a little patience, beginners can build a healthy compost system at home.
What Is Composting?
Composting is the natural process of breaking down organic materials, such as fruit peels, leaves, and grass clippings. Tiny organisms, insects, and worms help transform these materials into a dark, crumbly substance called compost.
Finished compost can improve soil structure, help retain moisture, and add organic matter. It is not a replacement for all garden products, but it is a useful addition to many types of soil.
The composting process needs four basic ingredients:
– Organic materials
– Air
– Moisture
– Time
A successful compost pile balances materials that provide carbon with materials that provide nitrogen.
Choose the Right Composting Method
The best composting method depends on your available space, the amount of organic waste you produce, and how quickly you want results.
Outdoor Compost Bin
An outdoor bin is a popular choice for people with a yard. You can purchase a ready-made bin or create a simple enclosure using wood, wire mesh, or other suitable materials.
Place the bin on bare soil if possible. This allows worms and other helpful organisms to enter the pile. Choose a location with good drainage and convenient access, but avoid placing it directly against a building or fence.
Compost Tumbler
A compost tumbler is a sealed container that rotates on a stand. Turning the container can be easier than using a garden fork, and the enclosed design may help keep pests away.
Tumblers are useful for small yards, patios, and people who want a tidy setup. However, they may hold less material than a traditional bin and can dry out or become too wet if the ingredients are not balanced.
Worm Composting
Worm composting, also called vermicomposting, uses special composting worms to break down food scraps. It works well in small spaces, including apartments, garages, and enclosed porches.
A worm bin should be kept away from extreme temperatures and direct sunlight. Use bedding such as shredded cardboard or paper, and add food scraps in small amounts. Avoid overfeeding the worms while they are getting established.
Kitchen Scrap Collection
If you are not ready to start a full compost pile, begin by collecting food scraps in a small container. This helps you learn how much organic waste your household produces and makes it easier to choose a suitable composting method later.
Use a container with a lid and empty it regularly to reduce odors.
Learn the Difference Between Green and Brown Materials
Compost needs a mixture of green and brown materials. These terms describe the role materials play in the process, not necessarily their color.
Green Materials
Green materials are generally rich in nitrogen. They help support the organisms that break down the pile.
Common examples include:
– Fruit and vegetable scraps
– Coffee grounds
– Tea leaves or tea bags without plastic
– Fresh grass clippings
– Fresh plant trimmings
– Small amounts of fresh manure from plant-eating animals
Brown Materials
Brown materials are generally rich in carbon. They provide structure and help air move through the pile.
Common examples include:
– Dry leaves
– Plain shredded cardboard
– Uncoated paper
– Small twigs
– Sawdust from untreated wood
– Straw
– Dry plant stems
A practical beginner approach is to add roughly two or three parts brown material for every one part green material. You do not need to measure precisely. If the pile is wet or smells unpleasant, add more brown material. If it is dry and inactive, add more green material and a little water.
What to Add to Your Compost
Most home compost piles can accept a wide range of plant-based materials. Chop or break larger items into smaller pieces when possible. Smaller pieces provide more surface area for organisms to work on and can help the pile break down faster.
Good materials include:
– Vegetable and fruit scraps
– Eggshells, crushed into small pieces
– Plain rice, pasta, and bread in moderate amounts
– Coffee grounds and paper filters
– Dry leaves
– Grass clippings
– Garden trimmings
– Untreated paper and cardboard
Keep a supply of dry leaves, shredded cardboard, or plain paper nearby. These materials are useful when the pile contains too many wet food scraps.
What Not to Add
Some materials can attract pests, create unpleasant odors, spread disease, or take a long time to break down. Beginners should leave these items out:
– Meat and fish
– Bones
– Dairy products
– Grease and cooking oil
– Pet waste
– Diseased plants
– Weeds that have gone to seed
– Glossy or heavily coated paper
– Coal or charcoal ash
– Treated or painted wood
Some advanced composting systems can handle materials that are not suitable for a basic backyard pile. If you are unsure about an item, check your local composting guidance or leave it out.
Build Your Compost Pile in Layers
Start with a layer of coarse brown material, such as small branches or dry stems. This helps air enter from the bottom. Add alternating layers of brown and green materials, finishing with a layer of brown material.
There is no need to create perfect layers every time you add scraps. You can also mix materials together as the pile grows. Cover fresh food scraps with leaves, soil, or shredded cardboard to reduce odors and discourage insects.
A pile that is at least three feet wide, three feet deep, and three feet tall can generate enough warmth for efficient decomposition. Smaller piles can still produce compost, but they may work more slowly.
Manage Moisture and Air
Your compost pile should feel like a damp, wrung-out sponge. It should not be soaking wet or completely dry.
If the pile is too wet:
– Add dry leaves, shredded cardboard, or straw.
– Mix the materials to improve airflow.
– Check whether the bin has enough drainage.
If the pile is too dry:
– Add a small amount of water.
– Mix in fresh grass clippings or food scraps.
– Cover the pile during very dry weather.
Air is also important. Turn the pile every week or two using a garden fork, shovel, or compost tumbler. Turning introduces oxygen and helps materials break down evenly. If turning is difficult, add coarse materials that create natural air spaces.
Handle Common Composting Problems
A strong unpleasant smell usually means the pile is too wet, compacted, or rich in green materials. Add brown materials and turn the pile.
Fruit flies may appear when exposed food scraps are near the surface. Bury scraps in the center of the pile and cover them with dry material.
A pile that is not changing may be too dry, too small, or lacking nitrogen-rich materials. Add a little water and fresh green material, then mix the pile.
If larger pests are a concern, use a secure bin with a lid and avoid adding meat, dairy, and oily foods.
Know When Compost Is Ready
Finished compost is usually dark brown, crumbly, and earthy-smelling. Most of the original materials should no longer be recognizable, although small pieces of twigs or eggshells may remain.
Depending on the method, materials, temperature, and weather, compost may take several months or longer to finish. Letting compost mature for a little extra time can improve its texture.
Use finished compost by mixing a few inches into garden soil, adding a small amount to containers, or spreading it around established plants. Avoid placing large amounts directly against plant stems.
Start Small and Stay Consistent
The easiest way to begin composting is to start with the materials you already have. Choose a convenient location, collect kitchen scraps, and add a steady supply of dry brown materials.
Do not worry about making every batch perfect. Composting is a natural process, and small adjustments can correct most problems. With regular attention, your household waste can become a valuable resource for healthier soil and a more productive garden.
