Learn how to make the best worm food for composting! 🪱🌿 Discover the perfect mix of organic scraps, kitchen waste, and nutrients to keep your worms healthy and your compost thriving. Turn leftovers into rich, fertile soil with this easy, eco-friendly guide! ♻️🌱
The Basic Worm Food Recipe:
This recipe focuses on a good balance of “greens” (nitrogen-rich) and “browns” (carbon-rich) for your worms.
Ingredients:
- Greens (50-75% of the mix):
- Fruit and vegetable scraps (avoid citrus in large quantities, oily foods, and processed foods) – Examples: apple cores, banana peels, melon rinds, carrot peels, lettuce, coffee grounds (with paper filters), tea bags (without staples)
- A small amount of crushed eggshells (provides grit and calcium)
- Browns (25-50% of the mix):
- Shredded paper (non-glossy, no colored inks if possible)
- Cardboard (torn into small pieces, remove tape and labels)
- Dried leaves (untreated)
- Coconut coir (moistened)
- Peat moss (use sparingly, not the most sustainable option)
Optional Enhancements (Use in moderation):
- Cooked and cooled grains (rice, pasta – no sauces or oils)
- Small amounts of bread (torn into pieces)
- Worm chow (available commercially)
Step-by-Step Instructions with Conceptual Images:
Step 1: Gather Your “Greens”

Conceptual Image: A collection of common fruit and vegetable scraps in a bowl – apple cores, banana peels, carrot tops, lettuce leaves, coffee grounds with a filter, and a few crushed eggshells.
Step 2: Prepare Your “Greens”

- Cut or tear larger food scraps into smaller pieces. This increases the surface area for the worms and microbes to break down the food faster.
- Crush eggshells finely.

Step 3: Gather Your “Browns”

Step 4: Prepare Your “Browns”

- Tear or shred paper and cardboard into smaller pieces. The smaller the pieces, the faster they will break down.
- If using dried leaves, you can crumble them.
- Moisten coconut coir or peat moss with water until
Step 5: Mix the “Greens” and “Browns”

- Combine your prepared “greens” and “browns” in a container.
- Mix them thoroughly to ensure a good balance. The mixture should feel damp but not soggy. If it’s too wet, add more “browns.” If it’s too dry, lightly mist it with water.
Step 6: Feeding Your Worms

- Bury the prepared worm food in a designated area of your worm bin. Avoid simply piling it on top, as this can attract fruit flies and create anaerobic conditions.
- Rotate feeding locations within your bin to prevent the buildup of uneaten food and to encourage the worms to move throughout the bedding.
- Feed your worms in small amounts initially, observing how quickly they consume the food. Adjust the amount you feed based on their consumption rate.
Important Considerations:
- Start slowly: Don’t overfeed your worms, especially when you’re just starting. It’s better to underfeed than overfeed.
- Observe your worms: Pay attention to how quickly they are eating the food. Adjust the amount accordingly.
- Moisture is key: The worm bin should be moist like a wrung-out sponge. Adjust moisture levels as needed by adding water or more dry “browns.”
- Avoid: Large amounts of citrus, oily foods, processed foods, meat, dairy, and pet waste. These can create odors, attract pests, and harm your worms.
- Patience: It takes time for worms to break down food. Don’t be alarmed if the food isn’t gone immediately
By following this recipe and these steps, you can create a nutritious and balanced diet for your composting worms, helping them thrive and produce valuable vermicompost! Remember that this is a general guideline, and you can adjust the ratios based on the types of scraps you have available and your worms’ preferences.
