Composting at home is easier than you think and is a great way to reduce the amount you throw away. You also increase your soil quality when you use finished compost.
Composting is a process where microbes break down food scraps, grass clippings and leaves into compost, a soil-like material that you can apply to your garden or yard. Compost is rich in nutrients, retains more water than regular soil, and reduces the need for fertilizers and pesticides.

Build your own
The following organizations offer helpful instructions on how to build a simple compost bin.
Choose a location for your bin that is convenient for you to add materials, out of direct sunlight to avoid overheating and away from roof drainage to prevent flooding your container.
The right recipe
To make compost, the micbrobes need four key ingredients: “browns”, “greens,” water and oxygen. Most water comes from food scraps, so you shouldn’t have to add any extra moisture. The pile should feel damp when you touch it, but not soggy. If the pile is too soggy, it will smell. Add air by turning your pile with a garden fork. Turning isn’t a requirement of compost piles but it speeds up the process.
Browns & greens
For every one kitchen pail of food added to your compost bin, add 3 big handfuls of dried leaves or straw. The best compost will come from a 3:1 ratio of browns to greens, but you don’t have to get scientific about it.
Browns (sources of carbon for the compost) | Greens (sources of nitrogen) |
- Dried leaves, garden debris, plant trimmings
- Straw and hay
- Wood (in small amounts): saw dust, wood chips, sticks
- Pine needles (in small amounts) and pine cones
- Shredded paper
- Tissues and napkins
| - Food: fruit and vegetable scraps, rinds, peels, egg shells
- Coffee grounds and filters
- Tea bags
- Fresh grass clippings (but it’s better to leave this on your yard)
|
DO NOT add these items because they can attract rodents or spread bacteria and plant diseases.
- Meat, bones, fish and dairy
- Fats: cooking oil and grease
- Feces: Pet and human
- Diseased plants & weeds that have gone to seed
- Ash from charcoal or coal
Using your compost
You do not have to use your compost. Your pile should shrink over time as compost slowly seeps into the ground.
Well maintained compost piles will be ready for use in two to four months, but it may take up to a year under other conditions. You’ll know your compost is ready when the pile is dark, crumbly and smells like fresh dirt. You can still compost in the winter, but the process may slow down.
Use your compost for many things:
- Mix compost in with your soil to improve quality.
- Use it to fill in low spots in your yard.
- Use it as mulch for landscaping and garden plants.
- Mix compost in the soil for potted plants. Do not add more than 50 percent compost to pots.

Indoor composting
Vermicomposting uses worms to break down the food scraps to create a vermicast, a product that can be used as a fertilizer. The worms are placed in a bin, so they don’t require much space and don’t smell.
Purchase a bin
Build your own
Put your bin in a location with moderate temperatures (55-70 degrees Fahrenheit), like under the sink, cupboard or in a closet.
Get worms
The best species of worms for vermicomposting is red wigglers (Eisenia foetida). One pound of red wiggles, or about a handful, is enough to start vermicomposting.
Ask your local garden center if they sell red wigglers or purchase them online:
Feed your worms
Start with a bedding at the bottom of your bin. Newspaper, cut into strips, or leaves are great materials. Over time, you will need to add additional bedding.
Add materials a few times a week, depending on how quickly the worms eat it. If the material is not eaten within a day or two, feed them a little less. Cover up fresh materials with newsletter or other bedding.
