Indigo milk cap mushrooms, also known as lactarius indigo, are a rare and sought-after mushroom that is prized for its distinctive blue color and unique taste. Growing indigo milk cap mushrooms is not as difficult as you might think, and with a little bit of patience and know-how, you can cultivate your own supply of this delicious and nutritious mushroom.

Here is a beginner's guide on how to grow indigo milk cap mushrooms:

Choose the right location

1. The first step in growing indigo milk cap mushrooms is to choose the right location. These mushrooms prefer to grow in the shade and need a moist environment to thrive. Look for a spot in your yard or garden that gets partial shade and has good drainage. Avoid areas with a lot of foot traffic or where pets may roam, as this can damage the delicate mycelium network.

Get the right substrate

2. Indigo milk cap mushrooms grow best on hardwood sawdust, but you can also use a mixture of hardwood chips and straw. It's important to sterilize the substrate before using it to prevent contamination. You can do this by boiling the substrate in a large pot or by using a pressure cooker.

Inoculate the substrate

3. Once the substrate has cooled, you can inoculate it with indigo milk cap mushroom spores. You can purchase spores online or from a local mushroom supplier. Mix the spores into the substrate, making sure to distribute them evenly. You can then place the substrate in a plastic bag or container and seal it to create a humid environment.

Wait for colonization

4. After inoculating the substrate, it will take several weeks for the mycelium to colonize the substrate. During this time, the substrate should be kept at a temperature between 65 and 75 degrees Fahrenheit. You can check for colonization by looking for white threads that appear on the surface of the substrate.

Create the right fruiting conditions

5. Once the substrate has been fully colonized, it's time to create the right conditions for fruiting. Indigo milk cap mushrooms prefer a cool, moist environment with high humidity. You can achieve this by misting the substrate regularly and covering it with a plastic bag or container. It's also important to maintain good air circulation to prevent mold growth.

Harvest and enjoy

6. After a few weeks, you should start to see indigo milk cap mushrooms forming on the surface of the substrate. When they are fully grown, simply twist them off at the base to harvest them. Rinse them off and they are ready to eat!

Growing indigo milk cap mushrooms is a fun and rewarding experience. With a little bit of effort, you can cultivate your own supply of this delicious and nutritious mushroom. Remember to always practice safe cultivation practices, such as sterilizing your substrate and keeping a clean growing environment. Happy growing!
