Composting is a fantastic way to recycle organic waste into nutrient-rich soil, but not all materials are compost-friendly. To ensure a successful composting process, it’s crucial to avoid certain ingredients that can disrupt decomposition or harm your garden. Here’s a comprehensive guide on what ingredients should not be added to compost.
What Ingredients Should Not Be Added to Compost?
Avoid adding meat, dairy, and oily foods to your compost. These items can attract pests and create unpleasant odors. Additionally, do not include diseased plants or chemically treated wood, as they can introduce harmful pathogens and toxins to your compost.
Why Avoid Certain Ingredients in Compost?
Adding the wrong ingredients to your compost can lead to several issues:
- Attracting Pests: Items like meat and dairy can attract rodents and other pests.
- Unpleasant Odors: Certain foods decompose poorly, creating foul smells.
- Pathogens and Toxins: Diseased plants and treated wood can introduce harmful elements.
Which Foods Should Be Excluded from Compost?
1. Meat and Dairy Products
Meat, bones, and dairy products should be avoided because they decompose slowly and can attract unwanted pests such as rats and flies. Additionally, they may produce strong odors as they break down.
2. Oily and Greasy Foods
Foods containing oils or fats, such as salad dressings or butter, should not be added to compost. They can coat other materials, slowing down the composting process and creating a barrier to decomposition.
3. Citrus Peels and Onions
While small amounts can be acceptable, large quantities of citrus peels and onions can increase the acidity of your compost, making it less hospitable for beneficial microbes.
Non-Food Items to Avoid in Compost
1. Diseased Plants
Avoid adding plants that show signs of disease or pest infestation. These can introduce pathogens that survive the composting process and spread to your garden.
2. Chemically Treated Wood
Wood treated with chemicals, such as pressure-treated lumber, should not be composted. These chemicals can leach into the compost and harm plants.
3. Pet Waste
Pet waste, especially from carnivorous animals, can contain harmful pathogens that are not killed in the typical composting process.
How to Maintain a Healthy Compost?
To keep your compost healthy and effective, focus on adding the right balance of green and brown materials:
- Green Materials: Grass clippings, vegetable scraps, and coffee grounds.
- Brown Materials: Dried leaves, straw, and shredded paper.
Ensure that your compost is well-aerated and moist, turning it regularly to promote even decomposition.

Cooked food is generally not recommended for composting as it often contains oils, fats, and salts that can disrupt the composting process and attract pests.
Is It Safe to Compost Weeds?
You can compost weeds, but avoid those that have gone to seed or are invasive, as they may survive the composting process and spread in your garden.
What About Eggshells?
Eggshells can be composted, but it’s best to crush them first. They decompose slowly but add valuable calcium to your compost.
Should I Compost Bread?
Bread can be composted in small quantities, but it should be mixed well with other materials to prevent mold and pests.
How Do I Fix a Smelly Compost?
A smelly compost pile often indicates excess moisture or lack of aeration. Add more brown materials and turn the pile to improve air circulation.
