How to Create Compost from Coffee Grounds and Kitchen Scraps

Composting is an eco-friendly practice that not only reduces kitchen waste but also enriches your garden soil with valuable nutrients. If you're an avid coffee drinker and you're looking for a way to put your coffee grounds and kitchen scraps to good use, then creating compost is the perfect solution. In this guide, we'll show you how to transform your coffee grounds and kitchen waste into nutrient-rich compost to boost the health of your garden.

Why Composting Matters

Before we dive into the specifics of creating compost from coffee grounds and kitchen scraps, let's explore why composting is such a vital practice for both the environment and your garden.

1. Reduces Waste: Composting diverts kitchen scraps from landfills, where they release harmful greenhouse gases as they decompose. This helps lower the carbon footprint of your household.

2. Enriches Soil: Compost is a fantastic natural fertilizer that improves soil structure, enhances water retention, and increases nutrient content. Your plants will thrive in healthier, more fertile soil.

3. Saves Money: By making your own compost, you reduce the need to purchase commercial fertilisers and soil conditioners.

4. Encourages Biodiversity: Composting supports the growth of beneficial microorganisms and earthworms in your garden, contributing to a diverse and thriving ecosystem.

Now, let's get into the nitty-gritty of creating compost from coffee grounds and kitchen scraps.

Materials Needed

To get started, you'll need a few basic materials:

1. Compost Bin: You can use a traditional compost bin or even a simple pile in your backyard. If you have the space, ideally two bins/piles are best so you can move partially composted material from one bin to the other, which turns it over and then you can start a new batch as well. For smaller gardens, see the section at the end of this article about using a bucket.

2. Coffee Grounds: Save your used coffee grounds. If you don't drink coffee, many cafes give away their used grounds for free.

3. Kitchen Scraps: Collect fruit and vegetable peels, eggshells, and other organic kitchen waste.

4. Browns: These are materials like dried leaves, shredded newspaper, or cardboard. They provide carbon to balance the nitrogen-rich coffee grounds and kitchen scraps. Pea straw is also good to provide some balance, and also some grass clippings.

5. Water: Moisture is essential for the composting process.

The Composting Process

Now that you have your materials, it's time to start composting. Follow these steps:

1. Layering: Begin by adding a layer of brown materials to the bottom of your compost bin or pile. This helps with aeration and moisture control.

2. Add Coffee Grounds and Kitchen Scraps: Alternate layers of coffee grounds and kitchen scraps with brown materials. This balance is crucial to prevent the compost from becoming too wet and smelly.

3. Keep It Moist: Regularly check the moisture level of your compost. It should be as damp as a wrung-out sponge. Water when necessary to maintain this consistency.

4. Aerate: Turn the compost pile every few weeks with a pitchfork or shovel. This adds oxygen and helps break down the materials faster.

5. Patience: Composting takes time. It can take several months to a year for your compost to fully mature. Be patient and let nature do its work. Pro tip: Use lime to help speed the process up – a couple of handfuls sprinkled between each layer will do the trick.

Using Your Compost

Once your compost is dark, crumbly, and has a pleasant earthy smell, it's ready to use in your garden. Here are some ways to utilize your homemade compost:

1. Soil Amendment: Mix your compost into the soil before planting. It will improve the soil's texture, nutrient content, and water-holding capacity.

2. Mulch: Spread compost on the surface of your garden beds and lightly dig it in to help retain moisture and suppress weeds.

3. Potting Mix: Create a custom potting mix by blending compost with other ingredients like sand and peat moss for your container plants.

4. Lawn Fertiliser: Apply a thin layer of compost to your lawn to encourage healthy grass growth.

Creating compost from coffee grounds and kitchen scraps is a sustainable way to reduce waste and improve your garden's soil. By following these simple steps and embracing the benefits of composting, you'll contribute to a healthier environment and enjoy the rewards of a thriving garden. So, next time you enjoy your morning cup of coffee, remember that those coffee grounds can do wonders for your garden, making it more vibrant and sustainable. Happy composting!

PS – if you have a smaller garden, here’s a great way to create a compost, right where you need it.

  1. Get a 10 or 20L plastic bucket (old paint buckets are good), and cut the bottom out of it.

  2. Dig a hole in your garden the size of the bucket, and drop it in so the top of the bucket is at ground level

  3. Fill the bucket with compost material following the steps above

  4. Place the lid on the bucket to prevent cats/rats etc getting in

  5. Turn the material over every so often

  6. Once it has composted, pull the bucket out of the ground, which will leave the compost behind as it has no bottom

  7. Dig a new hole and start again! Each compost pillar will do wonders to enrich the soil around it, and when you come to plant on top of it everything will flourish.
