Basics of Composting
Composting in Ann Arbor provides an excellent way to enhance your garden soil while promoting sustainability. This section will define compost and explore its benefits specifically for gardeners.
What Is Compost?
Compost is a soil amendment produced from the aerobic decomposition of organic materials. It is often termed "black gold" by gardeners for its ability to enrich the soil. This rich substance is created by combining materials like food scraps, leaves, and yard trimmings in a controlled environment. Through natural processes, these materials break down into a nutrient-rich humus that significantly improves soil quality.

Composting offers multiple benefits for both the environment and garden enthusiasts:
Soil Health: Compost acts as a soil conditioner, improving soil structure, texture, and aeration. It enhances the soil's ability to hold water and nutrients.
Nutrient Content: The process of composting creates a rich source of nutrients for plants. By adding compost to the garden, one ensures a slow release of substantial nutrients like nitrogen, phosphorus, and potassium.
Plant Growth: Enriched with compost, soil better supports plant growth, leading to healthier, more robust gardens.
Waste Reduction: Composting provides a substantial reduction in household waste, as organic materials are repurposed into valuable compost instead of taking up space in landfills.
By understanding the basics of compost and its benefits, residents can make an informed choice to contribute to a greener Ann Arbor, enhance their garden soil, and promote a healthier ecosystem.
Composting Methods in Ann Arbor
Ann Arbor, Michigan, offers residents several effective methods for transforming organic waste into valuable compost. These techniques cater to different lifestyles and preferences, ensuring that composting is accessible for all.
Backyard Composting
In Ann Arbor, backyard composting is a popular option for turning yard waste and kitchen scraps into nutrient-rich soil. Residents can utilize compost bins or piles sized appropriately for their space. Essential to backyard composting is maintaining a balance between 'greens' such as food scraps and 'browns' like dried leaves, ensuring proper decomposition.
Steps to start a backyard compost pile:
Choose a dry, shady spot near a water source.
Start with a layer of browns for aeration and drainage.
Add greens and mix or layer them with more browns.
Keep the pile moist and turn it regularly to aerate.
Community Composting
For those who do not have the space or prefer a more communal approach, community composting programs are available. The City of Ann Arbor offers curbside compost collection from April through November, where residents can contribute to larger composting initiatives.
Benefits of community composting:
Provides an option for apartment dwellers and others with limited space.

Basics of vermicomposting:
Set up a worm bin with proper bedding made of shredded newspaper or cardboard.
Add kitchen scraps, avoiding dairy, meat, and oily foods.
Maintain the bin in a cool, dark place and harvest the compost as needed.
By utilizing these composting methods, residents of Ann Arbor can reduce their environmental footprint and produce a rich amendment for their gardens and plants.
Starting Your Compost
When embarking on composting in Ann Arbor, selecting an appropriate compost bin and understanding how to build a fundamental compost pile are essential steps to ensure success.
Choosing a Compost Bin
Ann Arbor residents can utilize compost carts provided by the city for curbside compost collection, which operates from April through November. These carts are convenient for those with limited space or for beginners. For those interested in year-round composting, acquiring a bin that can insulate materials against the cold is beneficial for continued decomposition. It's important to consider a bin's size based on the amount of organic waste typically generated. Available compost options accommodate various household needs, ranging from small kitchen-top bins to larger outdoor systems.
Building a Compost Pile
Composting is a balance of carbon-rich materials, like twigs and dead leaves, and nitrogen-rich materials, such as food scraps and lawn clippings. Compost piles in Ann Arbor should begin with a base layer of twigs or small branches to improve aeration. This layer acts as the foundation for subsequent compost layers. When constructing a compost pile, alternating these layers is vital:
Nitrogen material (green)
Food scraps
Grass clippings
Carbon material (brown)
Leaves
Cardboard
Straw
Maintaining a ratio of about 3 parts brown to 1 part green is a basic rule for efficient decomposition. Regularly turning the compost pile accelerates the process and leads to more uniform results. Residents should ensure to cut up larger items and avoid composting diseased plants or invasive weeds to prevent spreading through the resulting compost.
Composting Guidelines
In Ann Arbor, composting is a valued, eco-friendly practice that diverts waste from landfills. The city provides specific instructions for what is and isn't accepted in its compost program.
What to Compost
Residents can compost a variety of organic materials. Most notably, leaves, grass clippings, and food scraps including fruits, vegetables, meat and bones, are acceptable. Ann Arbor also accepts BPI certified biodegradable products, which are designed to break down in composting facilities.
Acceptable Compost Materials:
Yard waste (e.g., leaves, grass)
Food scraps (e.g., fruits, vegetables, meat and bones)
BPI certified compostable products
What Not to Compost
It's equally important to know what should not go into the compost cart. Materials like plastics, even if labeled "biodegradable," that are not BPI certified, pet wastes, and diapers pose problems for composting facilities and should be kept out.

Maintaining Your Compost
Maintaining a compost pile in Ann Arbor requires attention to detail, especially considering the challenges posed by seasonal changes. Proper aeration, moisture management, and temperature control are essential for a successful compost.
Aeration and Moisture
For compost to break down effectively, it must have adequate aeration and moisture. Turn the pile regularly to introduce air, which facilitates the aerobic bacteria necessary for the decomposition process. The pile should be moist but not wet, akin to a wrung-out sponge. In winter, maintaining the right moisture balance can be challenging, but wrapping wet items before adding to the compost can help manage excess liquid.
Temperature and Microorganisms
The heat generated by microorganisms is integral to breaking down organic material. A compost pile should maintain a temperature between 90-140 degrees Fahrenheit for optimal activity, which may be monitored using a compost thermometer. In colder months, positioning your pile to receive maximum sunlight can help maintain warmth. Moreover, the presence of overwintering creatures, like Fireflies, can indicate healthy compost activity. For those unable to maintain outdoor composting in winter, Ann Arbor's curbside compost collection provides an alternative for organic waste, diverting it to a local composting facility.
