Mushroom blocks are most quickly broken with an axe, which drops 0-2 mushrooms. In the Java Edition of Minecraft, only cap blocks drop mushroom items, while in Bedrock Edition, stem blocks drop mushrooms as well. The blocks themselves can be retrieved by using a tool enchanted with Silk Touch. In the game, mushroom blocks can be placed under note blocks to produce a bass sound. In real life, mushroom blocks are grown in plastic grow bags filled with a sterilized, organic blend of sawdust, grains, and nutrients that feed the mycelium. Once the block is fully colonized and covered with mycelium, it is ready to fruit. The bags are cut open to allow in enough oxygen for the mushroom to fruit. After 3-7 days, the mushrooms are ready to harvest.

What You'll Learn

Harvesting with a knife
Harvesting shiitake mushrooms with a knife is fairly easy. First, get the block and put it on a piece of newspaper. Then, using a knife, cut the mushrooms off the top of the block. You can also twist the mushrooms off, but this might rip large chunks of sawdust and create extra cleanup. If you're not going to use the stalks, you can just cut the heads off the mushrooms and leave the stalks on the block.
After harvesting the mushrooms, leave the block somewhere to dry out with good airflow, such as on a shelf with a rack. This will prevent the outside of the block from going mouldy. After 3-4 weeks, the block should be very dry. Submerge it in water for approximately 12 hours. You can do this by filling a bucket with water and placing bricks or weights on top of the block to hold it underwater. Be careful not to make the block too wet, or it might fall apart.
Take the block out of the water and gently hit it on each side. Put it back in your fruiting container and repeat the misting routine. Your shiitake log is organic, so you can compost it, bury it, or add it to your worm farm.
It's important to note that the humidity and temperature of the environment can impact the growth and quality of the mushrooms. Commercial farmers typically simulate a temperature of 65-75°F and humidity of 80-90% for optimal mushroom growth.

Preparing the mushroom block
To begin preparing your mushroom block, you'll need to create a suitable environment for the mushrooms to grow. Commercial farmers often use plastic grow bags filled with a sterilized, organic blend of sawdust, grains, and nutrients that feed the mycelium (the white stuff). It is important to ensure that no salts are used in this process. The ideal temperature for mushroom growth is between 65-75°F, and humidity should be maintained between 80-90%bags in a controlled environment, such as a temperature-controlled room or a humidity tent.
Once you have prepared the growing medium and created the necessary environmental conditions, it's time to inoculate the mushroom block. This involves introducing the specific fungal species you want to grow into the prepared block. This can be done through various methods, such as using spawn bags or syringes containing the desired fungus. Make sure to handle the spawn or syringes with sterile techniques to avoid contamination.
After inoculation, the mushroom block will need time to colonize. During this stage, which typically lasts three weeks or more, the mycelium will grow and spread throughout the block. It is crucial to keep the mushroom block in a cool, dark place with temperatures below 80°F to ensure optimal colonization. Regularly monitor the mushroom block during this period, as it will need moisture and oxygen. You can maintain moisture by spritzing water around the block (not directly on it) and ensuring proper airflow by using a fan or keeping the square white filter patch accessible.
As the colonization process nears its end, you'll start to see "pins" or baby mushrooms forming. This is an exciting milestone, as it indicates that your mushroom block is almost ready to fruit. At this stage, it's important to increase the light and oxygen levels. You can do this by moving the block to a brighter location, such as a kitchen or bathroom, or placing it in a plastic tote, cardboard box, or greenhouse. Continue to maintain moisture and airflow during this stage.
Once the baby mushrooms have formed and you've adjusted the light and oxygen levels, it's just a matter of time until your first flush of mushrooms is ready to harvest. Depending on the variety, this can take anywhere from two to seven days. Keep a close eye on your mushrooms during this final stage, as you'll want to harvest them before the caps curl up and spores drop. With proper care and attention, you'll soon be able to reap the rewards of your hard work and enjoy your very own home-grown mushrooms!

Creating the right environment
Firstly, it is important to maintain a temperature-controlled environment, preferably between 65-75°F. This temperature range is ideal for mushroom growth. To achieve this, you can use a controlled environment, such as a Martha Tent or a Shotgun Fruiting Chamber, especially if the outdoor temperatures are too high. Maintaining the right temperature is essential for optimal mushroom growth.
Secondly, humidity plays a vital role in mushroom growth. Aim for a relative humidity level between 80-90%. While a humidity tent can help achieve this, it is not necessary. Regularly spritzing water around the mushrooms (not directly on them) can also help maintain humidity and moisture levels. This is especially important during the colonizing stage, which typically lasts three weeks or more, and when you notice the development of "pins" or baby mushrooms.
Additionally, light and oxygen levels are crucial factors in creating the right environment. During the initial stages, keep your mushroom blocks in a cool, dark place, ideally below 80°F. Once you notice the appearance of "pins" or baby mushrooms, increase the light and oxygen levels. You can move the mushrooms to a brighter location, such as a kitchen or bathroom, or place them in a plastic tote, cardboard box, or greenhouse. Ensure that the bag remains open to allow sufficient oxygen for mushroom growth.
Lastly, air circulation is essential. Use a fan to promote air movement, positioning it to face away from the mushrooms. This will help prevent the growth of unwanted mould and ensure that your mushrooms receive an adequate supply of fresh air. By following these steps and maintaining the right temperature, humidity, light, oxygen, and air circulation levels, you can create the ideal environment for mushroom growth.

When to harvest
Knowing when to harvest your mushroom blocks is key to a successful crop. You need to wait for the mycelium to fully colonize your block and for the baby mushrooms to develop. This process can take around two to three weeks, and you will know the mycelium is ready when you see white "pins" or baby mushrooms start to appear.
At this point, you need to move your mushroom blocks to a brighter location with more oxygen. You should also start to water them more frequently. A good way to do this is to spritz water around the mushrooms (not directly on them) and to keep them in a moist environment like a kitchen or bathroom. You can also place them in a plastic tote, cardboard box, greenhouse, or humidity tent.
After 2-5 days, your mushrooms will be ready to harvest. You will know they are ready when the caps are still folded down and not dropping spores. If you leave them too long, the edges will flatten upwards and start to drop spores. You can still eat them at this stage, but you should take them outside to avoid spores spreading indoors, which can cause problems for people with allergies. Harvest your mushrooms with a knife before the caps curl up, and compost the block after harvest.

What to do after harvesting
After harvesting your mushrooms, there are a few important steps to take to ensure the continued health and productivity of your mushroom blocks. Here are some detailed instructions:
Firstly, it is important to properly dispose of the harvested mushroom block. The block can be donated to a local mushroom farm or composted to grow more mushrooms. Composting can be done by smashing the block and mixing it with your compost pile, or by using it as mulch in your garden. If you choose to compost, it is important to make sure that the block is kept moist and has adequate airflow. You can do this by spritzing it with water daily and ensuring that there is a square white filter patch directly accessible for airflow.
Secondly, if you plan to reuse the mushroom block to grow more mushrooms, there are a few steps to follow. After harvesting, leave the block in its existing bag and place it in a cool, shady spot, maintaining a temperature of 65-75°F. It is important to keep the block moist and provide adequate airflow during this time. You can do this by spritzing water around the block (not directly on it) and ensuring the bag has a slit for airflow.
Additionally, keep an eye out for any new "pins" or baby mushrooms that start to form. When you see these, it's time to move your mushroom block to a brighter location with more oxygen, such as a kitchen or bathroom, or place it in a plastic tote, cardboard box, greenhouse, or humidity tent. Continue to water frequently, and within 2-5 days, a new "flush" of mushrooms will be ready for harvest.
Finally, it's important to know when your mushroom block is spent and ready to be discarded. After several times fruiting, the block will be done and can be composted as described earlier. However, if you see green, moldy spots on the block at any time, it is no longer viable and should be fed to your compost rather than reused.
