A Cheatsheet: Your Guide To Vermicomposting

What is Vermicomposting?

Vermicomposting is the process of using worms to break down organic waste materials, such as kitchen scraps and yard waste, into nutrient-rich compost.

Benefits of Vermicomposting

- Produces high-quality compost for plants
- Reduces waste sent to landfills
- Creates a sustainable solution for organic waste management
- Enhances soil structure and fertility
- Increases soil water-holding capacity
- Boosts plant growth and yield

Getting Started

To start vermicomposting, you will need:
- A worm bin
- Redworms (Eisenia fetida or Lumbricus rubellus)
- Organic waste materials (e.g. kitchen scraps, coffee grounds, shredded paper)
- Bedding materials (e.g. shredded newspaper, coconut coir)
- A moisture meter (optional, but helpful to monitor moisture levels)

Setting Up Your Worm Bin

1. Choose a suitable container with drainage holes for your worm bin.
2. Add a layer of shredded newspaper or coconut coir as bedding.
3. Moisten the bedding, aiming for a moisture level similar to a squeezed-out sponge.
4. Introduce the worms to the bin and cover them with a layer of bedding.
5. Place the bin in a cool, shaded area, away from direct sunlight.
6. Regularly monitor and maintain moisture levels and add organic waste to the bin as needed.

Feeding Your Worms

- Avoid feeding your worms meat, dairy, oily or salty foods.
- Feed them vegetable and fruit scraps, coffee grounds, tea leaves, and crushed eggshells.
- Chop or blend the food scraps to accelerate decomposition.
- Bury the food scraps under the bedding to prevent odor and fruit fly issues.
- Begin with small amounts and gradually increase the feed as the population expands.
- Avoid overfeeding to prevent odors, acidity, or pest problems.

Harvesting Vermicompost

1. Stop feeding the worms a few weeks before harvesting to allow them to process remaining waste.
2. Move the compost to one side of the bin and add fresh bedding and food to the other side.
3. Wait for the worms to migrate towards the new food source, making it easier to collect the compost.
4. Collect the vermicompost from the side where the worms have migrated.
5. Separate the worms from the finished compost using methods like light or hand sorting.
6. Repeat the process to continue vermicomposting and producing nutrient-rich compost.

Troubleshooting Common Issues

- Odor: Adjust moisture levels, avoid overfeeding, add dry bedding, or bury food scraps deeply.
- Pests (e.g. fruit flies): Bury food scraps deeper, ensure proper ventilation, and cover the bin securely.
- Worms trying to escape: Check moisture levels, bedding, and temperature to create an optimal environment for your worms.
- Slow decomposition: Shred or chop materials into smaller pieces, maintain proper moisture levels, and ensure sufficient aeration.
- Acidic compost: Balance carbon-to-nitrogen ratio by adding more carbon-rich materials (e.g. shredded paper) or adjusting feed types.

Composting is a great way to reduce waste as well as add precious nutrients to your garden. But it isn't the only way to nourish your soil. Vermicomposting is a fascinating and often overlooked way to turn your kitchen scraps into high-grade compost. You can harness the power of worms to do the composting for you and transform your compost bin into a vermicomposter.

What Is Vermicomposting?

Vermicomposting is an ancient form of composting that harnesses the power of worms to break down kitchen waste into nutrient-rich compost. Using a special bin, such as a worm farm, the home composters can feed their waste to the worms, who then decompose it into high-grade compost in a matter of weeks. This kind of compost is incredibly rich in nutrients and full of health-promoting bacteria. Additionally, it is an effective and low-maintenance way to reduce waste and help the environment.

How To Get Started With Vermicomposting

If you are interested in vermicomposting, the first step is to gather the necessary materials. You will need a worm bin, which can be purchased online or at a gardening center. You can also make your own from a plastic storage bin. Once you have a bin, the next step is to create a healthy environment for your worms. This includes adding bedding material, such as shredded newspaper or coconut coir, and a moist source of food, such as vegetable peels and scraps.

Adding The Worms

Once the bedding has been added to the bin, it's time to add the worms. Red worms, such as the red wiggler, are the most commonly used for vermicomposting. The worms can be purchased online or at a local bait shop. Once you have the worms, they should be added to the compost bin and allowed to acclimate to their new environment.

Feeding The Worms

The worms will need to be fed about once a week in order to keep them healthy. Kitchen scraps, such as vegetable and fruit peels, are ideal for this. Always make sure that the scraps are moist and free of any chemical residue. The worms will also need a source of calcium, such as egg shells or crushed limestone.

Harvesting The Compost

Once the worms have broken down the kitchen scraps into nutrient-rich compost, it's time to harvest the compost. This can be done by carefully sifting the compost from the bin and setting aside the worms and un-decomposed materials. The compost can then be used in the


What is vermicomposting?

Vermicomposting is a process of composting organic waste using worms. It involves the breakdown of organic materials by earthworms and other microorganisms to produce nutrient-rich compost known as vermicast.

Why should I vermicompost?

Vermicomposting is an excellent way to reduce your carbon footprint and turn kitchen scraps and garden waste into a valuable fertilizer. It enriches your soil, promotes healthy plant growth, and reduces the need for chemical fertilizers.

How do I start vermicomposting?

To begin vermicomposting, you'll need a worm bin or vermicomposting system. Choose a suitable container, such as a plastic bin or wooden box, and create a bed of bedding material like shredded newspaper or coconut coir. Add worms, preferably red worms (Eisenia fetida), and begin feeding them organic waste.

What can I feed my composting worms?

Composting worms eat a variety of organic matter, including fruit and vegetable scraps, coffee grounds, tea leaves, crushed eggshells, and garden waste like leaves and grass clippings. Avoid feeding them meat, dairy, oily foods, and citrus peels as they can attract pests or harm the worms.

How do I maintain a worm bin?

Keep your worm bin in a shaded, cool area to prevent overheating. Maintain a moist but not waterlogged environment by regularly spraying the bedding. Feed your worms small amounts of food scraps, burying them under the bedding. Every few months, harvest the finished vermicast by removing the top layer and collecting the dark, crumbly compost.

Can I use vermicompost in my garden?
