Backyard Composting
Composting at home is easy; all it takes is a little time, effort and patience. 

Why Compost?
Composting organic materials such as yard trimmings and food scraps reduces the amount of waste that ends up in the Westchester County Incinerator. 

By using compost in your garden, you return organic matter to the soil. Compost enriched soil holds more nutrients and water, improves soil structure and drainage, and enhances plant growth. 

Compost can be mixed directly into your soil, applied as a layer of mulch, used in a thin layer on your lawn, or soaked in a bucket to make “compost tea” for watering indoor and outdoor plants.

How it Works
The breakdown of kitchen and garden waste occurs through the work of micro-organisms (bacteria, fungi) and macro-organisms (worms, millipedes, and other bugs). As they work to break down the materials, the pile will heat up and decompose until you are left with compost!

What Can I Compost?
Good compost needs four things to thrive: greens (nitrogen), browns (carbon), air (oxygen) and water. Add equal parts greens to your browns.

Greens (30%) – nitrogen source provides the main bodybuilding proteins for the microorganisms breaking down your compost pile

  • Grass clippings
  • Food scraps
    • Fruits and vegetables 
    • Coffee grounds
    • Tea bags 
    • Egg shells

Browns (70%) – carbon source provides structure for the pile, allowing air to flow more freely

  • Dry leaves
  • Shredded paper
  • Wood Chips
  • Straw
  • Small twigs

Air – compost microorganisms need oxygen! Turning or mixing the pile regularly will add air and speed up breakdown. 

Water & Sun – composting works best when the materials are warm and damp. Place your bin in a sunny location and add water if it’s dry. If the pile is too wet, add some leaves, shredded newspaper or sawdust. 

Composting Methods
The following methods can be used to compost in your backyard:

Holding Bins and Piles
Yard and kitchen waste can easily compost in piles or holding bins, which are simple wood, plastic or wire containers. A variety of easy to use bins can be found at hardware and garden centers.

This bin tumbles the waste for aeration by spinning the drum. Some tumblers also collect liquid at the base of the composter so you can produce compost tea. Simply add waste as it accumulates and turn the barrel. We recommend a two sided tumbler so that you can constantly add material to one side while the other side finishes composting.

Multi-Bin System
This compost system is a series of holding bins used for building and turning active compost piles. They are most appropriate for large volumes of yard waste and produce a high quality compost.

Helpful Hints
1. Be sure to cover all new food that is added to the compost pile with browns. This will keep away unwanted pests. 

2. If your pile is too soggy, there could either be too much water or greens. Just add more browns and turn the pile. 

3. If your pile is too small it could prevent the micro-organisms from breaking everything down. Increase the size of the pile by adding more material.

4. If your pile is not breaking down, there may be too many browns. Add more greens and mix them into the pile.

How long will composting take?
Compost can take two to four months to breakdown. The finished compost is a rich material that looks like soil and has an earthy smell. Once you have finished product, place your pile in an open space for approximately two weeks to aerate before using the compost in your garden.

Do I need to cut my scraps into small pieces before composting?
Cutting scraps helps compost break down faster by increasing the surface area of compostable material. 

What can’t I compost at home?

  • NO meat, fish, poultry, bones or fatty foods such as dairy products and oils. These attract animals and do not compost well in a home system. 
  • NO cat litter or dog feces. These materials may contain disease organisms that remain after composting. 
  • NO plants that have been treated with herbicides or pesticides.

Does my compost bin/pile need to be in the sun?
Putting your bin/pile in the sun will increase the temperature of the compost, so the bacteria and fungi will work faster. This might also make your compost dry out faster so keep an eye on the moisture level.
