Mushroom cultivation has been growing in popularity, and one of the most intriguing practices to emerge recently is the cultivation of mushrooms in used coffee grounds. This sustainable approach not only provides an ideal growing environment for mushrooms but also helps reduce waste and utilize a resource that often ends up in landfills. This comprehensive guide on mushroom growing in coffee plants will explore the unique techniques and methods that can mean the difference between a successful and unsuccessful mushroom harvest.
Why grow mushrooms in coffee grounds?
Used coffee grounds are packed with nutrients that mushrooms need to grow, such as nitrogen and other minerals. Additionally, these grounds provide a growing medium with a suitable texture and pH level for different types of mushrooms. Moreover, using used coffee grounds is an excellent way to recycle them, reducing the amount of waste that ends up in landfills.
Choosing the right mushroom type
Not all mushrooms will grow well in coffee grounds. Some of the most popular options for growing in coffee grounds include oyster mushrooms, shiitake mushrooms, and other wood-loving varieties. These mushrooms thrive in nutrient-rich environments like coffee grounds, making them ideal candidates for this type of cultivation.
Oyster Mushrooms
These fast-growing, edible, and versatile mushrooms are an excellent choice for beginners as they are easy to grow and require minimal maintenance. Oyster mushrooms also have a characteristic taste that pairs well with many coffee types.
Shiitake Mushrooms
Shiitake mushrooms are popular in Asian cuisine and have a delicious umami flavor that enriches any dish. Although they require more time and attention than oyster mushrooms, their unique taste and health benefits make them well worth the effort in coffee ground cultivation.

Preparing the coffee grounds for mushroom growing
Before beginning the mushroom cultivation process, you'll need to properly prepare the coffee grounds. Here's how:
- Ensure the coffee grounds are properly dried before using them. This can be done by spreading them out on a tray and letting them air dry for several hours or placing them in a low-temperature oven until they reach the desired consistency.
- Pasteurizing the coffee grounds is essential to kill any bacteria or contaminants present. To do this, place the grounds in a large pot with water and heat to 165°F for 90 minutes. Afterwards, let the grounds cool to room temperature before proceeding.
Setting up the growing environment
Once the coffee grounds are prepared, it's time to set up the growing environment. Consider the following steps:
- Create a substrate mixture using the pasteurized coffee grounds, mushroom spawn, and a small amount of gypsum (to balance the pH). Mix the substrate thoroughly and then distribute it into the desired growing containers or bags.
- Once the containers are filled, seal them with a breathable material such as plastic wrap or a coffee filter secured with a rubber band. This will allow for air exchange and prevent contaminants from entering the growing environment.
- Store the sealed containers in a dark and temperature-controlled environment. The ideal temperature for most mushroom varieties is between 60-75°F.
- Monitor the growth of mycelium (the root-like structures of mushrooms) through the substrate until it is fully colonized. This process can take anywhere from 1 to 3 weeks, depending on the mushroom type and growing conditions.
- When the substrate is fully colonized, transfer the containers to a fruiting chamber or an environment with high humidity, appropriate temperature, and indirect light. This will promote the fruiting of the mushrooms.
Mushroom Growing In Coffee Plant Example:
A practical example of mushroom growing in coffee plants might involve setting up a small indoor container garden using easily accessible materials. One option is to utilize mason jars filled with prepared coffee ground substrate and sealed with a coffee filter. Place a layer of oyster mushroom spawn in the coffee ground substrate, make sure the jars have adequate air exchange, and store them in a dark, temperature-controlled environment until fully colonized.
