As we celebrate Earth Day and reflect on ways to reduce our environmental impact, one simple yet powerful practice stands out: composting. Composting is a natural process that transforms organic waste into nutrient-rich soil, reducing landfill waste and greenhouse gas emissions while nourishing the Earth.

Benefits
- Reduces Waste – Composting diverts organic waste from landfills, reducing methane emissions and minimizing overall waste production.
- Improves Soil Health – It enriches soil with essential nutrients, enhances moisture retention, and supports beneficial microorganisms, leading to healthier plants.
- Supports Biodiversity – Healthy compost attracts earthworms, beneficial insects, and microbes, creating a thriving ecosystem in your garden or farm.
Getting Started
- Traditional Bin or Pile – This method involves creating a compost pile in your backyard or using a bin to contain the materials. Alternate layers of green (nitrogen-rich) and brown (carbon-rich) materials, keep it moist, and turn it occasionally to speed up decomposition. This is a great option for those with outdoor space and time to maintain the pile.
- Trench or In-Garden – Instead of building a pile, you can bury food scraps and organic materials directly into your garden beds. Simply dig a trench about 12 inches deep, add compostable materials, and cover with soil. Over time, the materials break down, enriching the soil with nutrients. This method is low-maintenance and perfect for gardeners who want to improve soil health without managing a compost bin.
- Bokashi Method – A great option for small spaces or indoor composting, Bokashi uses a fermentation process to break down food waste (including dairy and meat) in an airtight container. After a few weeks, the material can be buried in soil or added to a traditional compost bin for further decomposition. This is ideal for apartment dwellers or those looking for a fast, odor-free method.
Compost Do’s and Don’ts
What you CAN use
- Fruit and vegetable scraps
- Coffee grounds and filters
- Tea bags (SOME! Remove staples if present and check for plastic content)
- Eggshells
- Nut shells (avoid walnut shells as they contain juglone, which can be toxic to plants)
- Yard trimmings (grass clippings, leaves, weeds without seeds)
- Plant-based kitchen scraps (rice, pasta, bread – although, these are best for Bokashi method)
- Shredded paper (newspaper, printer paper, cardboard)
- Wood chips and sawdust (untreated)
- Dryer lint (from natural fibers)
- Hair and fur (pet hair, human hair)
- Wood ashes (in moderation)
- Manure from herbivorous animals (horse, cow, rabbit, chicken)
What you CAN’T use
- Meat, fish, and dairy products (unless you’re using the Bokashi method)
- Oily or greasy foods (can disrupt composting process)
- Diseased plants (risk spreading pathogens)
- Weeds with seeds (may germinate in compost)
- Pet waste from cats or dogs (can contain pathogens harmful to humans)
- Coal or charcoal ash (may contain toxins)
- Glossy or colored paper (contains chemicals harmful to compost)
- Synthetic fibers (polyester, nylon)
- Plastic or metal (non-biodegradable materials)
- Chemically treated wood (pressure-treated or painted wood)
- Charcoal briquettes (contain additives and chemicals)
- Non-organic materials (glass, plastic, metal, rubber)
Using Compost in Your Garden
- Once your compost is fully decomposed and resembles dark, crumbly soil, it’s ready to use in your garden or landscaping projects.
- Spread compost around plants as a natural fertilizer and soil conditioner, or mix it into garden beds to improve soil structure and fertility.
- Compost can also be used as mulch to retain moisture, suppress weeds, and regulate soil temperature in garden beds and containers.
As we celebrate Earth Day and commit to living more sustainably, composting offers a practical and rewarding way to reduce waste, nourish the Earth, and cultivate healthy, vibrant ecosystems. By embracing composting in our homes and communities, we can each play a part in creating a greener, more resilient planet for generations to come. I hope this beginner’s guide to composting inspires you to start your journey today.
