What Types of Materials Can be Composted in a Tumbler?

Composting is a natural process that transforms organic materials into nutrient-rich compost, which can be used to improve soil fertility and promote healthy plant growth. Composting in a tumbler is a convenient and efficient method that allows for easy turning and aeration of the compost pile. To achieve optimal results, it is important to know what types of materials can be composted in a tumbler.

Green Materials

Green materials, also known as nitrogen-rich materials, provide a source of nitrogen for the composting process. These materials are typically fresh and moist, and they help to activate the decomposition process. Examples of green materials that can be composted in a tumbler include:

• Grass clippings
• Vegetable and fruit scraps
• Coffee grounds and tea leaves
• Green plant trimmings
• Seaweed and algae

Brown Materials

Brown materials, also known as carbon-rich materials, provide a source of carbon for the composting process. These materials help to balance the nitrogen-rich green materials and provide structure to the compost pile. Examples of brown materials that can be composted in a tumbler include:

• Dry leaves and twigs
• Straw and hay
• Shredded newspaper and cardboard
• Wood chips and sawdust
• Dried plant stalks

Avoid These Materials

While many organic materials can be composted in a tumbler, there are some materials that should be avoided to prevent potential issues. These materials include:

• Meat, fish, and dairy products (they can attract pests)
• Grease, oils, and fats (they can slow down the composting process)
• Coal ash and charcoal (they can contain harmful substances)
• Plants treated with pesticides or herbicides (they can contaminate the compost)
• Large branches and woody materials (they can take longer to decompose)
