Growing Blue Oyster Mushrooms

What Is Blue Oyster Mushroom? Benefits, Uses, & Growing Tips (3)

Blue oyster mushroom cultivation is one of the easiest to do at home. Moreover, the freshness of homegrown blue oysters is really unbeatable.

You get to produce several clusters of blue oysters, which you usually buy in a price range of 6$ to $20. The better the quality, the higher the price.

Naturally, they are found growing on the dead and decaying wood. However, to DIY the cultivation process, some prefer to use a commercial mushroom growing kit while others make their own with:

  • Spawn
  • Hay
  • Aspen Wood Chips
  • Pickling Lime
  • Bucket (with holes)
  • Plastic Bag

The blue oyster is sensitive to CO2, humidity, light, and air exchange. Whether you are cultivating indoors or outdoors, make sure you provide the right oyster mushroom growing conditions to see them thrive in clusters.

With proper growth, they will fill the bucket with thick mushroom spores. So, how to do it? Let’s find out:

  1. Take a dark-colored 5 gallon bucket (to reflect light) and drill holes of ¼ at every few inches (blue capped mushrooms will grow out of these holes). Also, make 1/8 holes at the bottom for water drainage
  2. Soak the hay or aspen chips in hot water (mixed with pickling lime is optional) overnight, then remove the water from it
  3. Layer the chips and oyster mushroom spawn (5 grain spawn) in the bucket. Repeat the layering and make sure to keep the chips or hay as the top layer
  4. Leave the prepared kit in a dark space and let the mushrooms colonize. You can also cover it with a black plastic bag to provide enough humidity (more than 70%) or keep a humidifier along with it
  5. Also, keep the growing temperature maintained between 15°C (59°F) to 21°C (70°F)

Note: If you are using old mushroom spawn, make sure to remove any mold.

Here is a video demonstration for growing blue oyster mushroom:

You may start to notice baby oyster mushrooms growing out of the holes after 2 to 3 weeks. So, how do you know when to harvest oyster mushrooms?

The simple hint is when you notice the blue mushrooms have started to curl up. It means they are about to drop or leave the spores. This is the perfect time for harvesting oyster mushrooms.

But, how to cut oyster mushrooms?

Simply, pick a sharp knife and cut right at the cluster (take the mushrooms as a whole).

After harvesting the blue oyster mushroom, take the inside material from the bucket and lay it on a straw bed to get the second growth out of it.

Now that you have finished harvesting blue oyster mushrooms, here comes the storage. So, how can you store oyster mushrooms?

Well, there are two ways to do it:

  • Place the blue oysters in a plastic bag and keep them in the fridge. They will have a fresh taste for 6-7 days
  • Keep the blue mushrooms (unwashed) without cutting in a brown bag and seal the top of it. Place this in the refrigerator for the longevity of freshness
