What Can I Compost? A Comprehensive Guide to Sustainable Gardening

Are you passionate about reducing waste and embracing sustainable lifestyle choices? Composting is a fantastic way to utilize kitchen scraps and yard waste, transforming them into nutrient-rich soil for your garden. In this blog post, we’ll explore the different items you can compost to achieve an eco-friendly and thriving garden.

The Basics of Composting

Before diving into what can be composted, let’s quickly review the fundamentals. Composting is a natural process where organic materials decompose over time, resulting in nutrient-dense humus that enriches your soil. By mimicking nature’s recycling system, you decrease landfill contributions while improving the health of your garden.

Fruit & Vegetable Scraps

Your kitchen likely holds numerous composting treasures! Fruit peels, vegetable trimmings such as carrot tops or mushroom stems, and even coffee grounds are all excellent additions to your compost pile. Just avoid adding large quantities of citrus fruits as they may alter the acidity levels.


  • Cut larger scraps into smaller pieces for faster decomposition.
  • Be sure to remove any stickers or labels from produce before adding them to your pile.
  • Avoid using spoiled or moldy fruits/vegetables as they might introduce harmful pathogens.

Eggshells & Coffee Grounds

Packed with nutrients like calcium carbonate, eggshells make a perfect addition to your compost bin. Crush them beforehand for quicker breakdown. Similarly, coffee grounds are rich in nitrogen and help balance carbon-heavy materials like dry leaves or straw within the composter.


  • Do not include eggs in their entirety, as they could attract pests.
  • Rinse both eggshells and coffee grounds before adding them to remove any residue, like salt or oils.

Yard Waste

Your yard also plays a crucial role in providing compostable materials. Grass clippings, leaves, small twigs, and pruned branches can all be added to your compost pile. However, avoid using diseased plant matter or invasive weeds that might survive the decomposition process and harm your garden later on.


  • Mix grass clippings with other carbon-rich materials (like dry leaves) to maintain proper air circulation within the pile.
  • Avoid adding large tree branches that take longer to break down unless you have a wood chipper/shredder available.

Paper & Cardboard

Recycling paper is fantastic but composting it is even better! Shredded newspaper or cardboard provides a carbon source for your compost bin. Avoid glossy papers or those treated with chemicals as they won’t break down as efficiently.


  • Dampen shredded paper/cardboard slightly before layering it into the compost pile for faster decomposition.
  • Avoid including plastic-coated cardboard such as pizza boxes since they cannot decompose properly.

Natural Fibers & Yard Byproducts

If you enjoy crafting from natural fibers like cotton or wool, consider introducing fabric scraps into your compost bin. Additionally, hair trimmings from human/animal grooming sessions can contribute valuable nitrogen while deterring certain pests due to their scent!


  • Ensure any fabrics added are free from synthetic materials or dyes.
  • Avoid adding hair treated with chemicals like dyes, as it may not decompose effectively.

What to Exclude from Your Compost Pile

While many items can be composted, some should never find their way into the bin. Avoid including meat, dairy products, oil/fat residues, pet waste (including cat litter), and diseased plants. These materials could attract unwanted pests or introduce harmful pathogens that disrupt the composting process.

In Conclusion

Composting is an incredible journey towards sustainable gardening practices and reducing your ecological footprint. By understanding what can be composted and following a few simple tips for effective decomposition, you’ll soon witness the transformation of “waste” into precious soil enricher. So let’s roll up our sleeves and start composting today!
