The combination of nutrient-rich coffee grounds and the versatile properties of mushrooms enables people to transform their everyday waste into a delicious and nutritious delight. In this guide, we'll explore the types of mushrooms that grow well with coffee grounds, how to cultivate them and provide a clear, step-by-step example for you to follow. Ready to embark on a fungi-filled adventure? Read on to dive into the world of mushrooms and coffee grounds.
Why Grow Mushrooms with Coffee Grounds?
Coffee grounds are a rich source of nutrients that would otherwise go to waste. They are packed with nitrogen, potassium, and phosphorous, which are essential components for plant growth. By using coffee grounds as a medium for growing mushrooms, you not only promote sustainability but also get to enjoy the health benefits of these organic, homegrown fungi.
Choosing the Right Mushrooms
While many mushroom varieties can grow in coffee grounds, some are better suited to this environment than others. Here are a few popular choices:
Oyster Mushrooms
Oyster mushrooms are among the easiest to cultivate and highly recommended for beginners. They thrive in the nutrient-rich environment provided by coffee grounds. They also have a diverse range of culinary applications due to their mild, unique flavor.
Shiitake Mushrooms
Another fantastic option, Shitake mushrooms, are also relatively simple to grow using coffee grounds. Well-known for their distinct, earthy flavor, they have become a popular addition to many recipes.

Wine Cap Mushrooms
Lastly, Wine Cap mushrooms, or King Stropharia, are perfect for coffee ground cultivation as well. They are adaptable to various substrates, and their robust, meaty taste makes them a valuable addition to any dish.
Preparing the Growing Medium and Spawn
To start growing mushrooms in coffee grounds, you'll need the following materials:
- Freshly used coffee grounds
- Mushroom spawn (can be purchased online or at a gardening center)
- A large, clear plastic container with a lid
- A spray bottle
Note: It's crucial to use fresh coffee grounds immediately after brewing, as they can quickly develop mold, which may negatively impact the mushroom growth.
Cultivating Mushrooms with Coffee Grounds
Once you've gathered the necessary supplies, follow these steps to grow your mushrooms:
1. Start by sterilizing your container with a mild bleach solution to minimize potential contamination.
2. Layer the bottom of the container with a 1-inch layer of fresh, moist coffee grounds.
3. Sprinkle a thin layer of your chosen mushroom spawn onto the coffee grounds.
4. Continue alternating layers of coffee grounds and spawn, ending with a coffee grounds layer. Ensure you do not pack down the layers too tightly to allow for proper air circulation.
5. Lightly mist your layered substrate with water. Keep the moisture level consistent but avoid over-watering, which can cause mold issues.
6. Cover your container with the lid, leaving small air gaps for ventilation.
7. Store the container in a dark, cool place, around 65°F to 75°F (18°C to 24°C).
8. Check your container daily for signs of mycelium growth (white, cotton-like threads). This may take up to two weeks. Maintain the moisture level by misting as needed.
9. Once you see significant mycelium growth, introduce the container to indirect sunlight for a few hours per day. This will encourage the mushrooms to fruit.
10. Harvest your mushrooms when the caps have fully opened and enjoy your homegrown fungi!
