What do you need to grow them?

Growing button mushrooms is one of the easiest type of mushroom to grow and does not require many supplies.
Here’s what you’ll need from your local garden store…

  • 2-by-3 foot growing tray 6 to 8 inches deep (you can build this or buy it)
  • Compost
  • Mushroom spawn
  • Peat moss
  • A piece of wood or flat object
  • Water mister
  • Newspapers
  • Water, proper temperature, and a few weeks is all that you need to grow delicious button mushrooms.


How to begin cultivation

Step 1: Place the well-rotted compost into the growing tray and water. Be sure that the compost is completely wet but you want it moist not soggy.
Step 2: Get 1 to 2 cups of the dry button mushroom spawn flakes and mix it into the compost. You’ll need to loosen the mixture and put it into loose piles in the tray. With a piece of wood or something flat press the compost and spawn mixture into the tray. Now let it set over night.
Step 3: Keep the temperature between 65 and 70 degrees Fahrenheit for 2 to 3 weeks, misting daily with your spray bottle.
Step 4: Once you see white webbing on the surface of the soil you’ll need to apply a 1 ½ inch layer of moist peat moss and cover with a few layers of newspapers. The newspaper must be kept moist. Continue to evenly spray the newspaper twice daily. Maintain a temperature of 55 degrees Fahrenheit.
Step 5: After 10 days remove the newspaper and continue to mist twice daily.
Step 6: In a few days you’ll see tiny white pinheads sprouting.

Once the button mushrooms reach your desired size you can pick them and new mushrooms will grow in 10 to 14 days. You’ll have an endless supply for 3 to 6 months using this method and then you’ll need to start the process again from step one…

Or alternatively, often the best way to begin is to start with a ready made mushroom growing kit. These kits are very cheap, come with everything you need to get started, and generally will start producing mushrooms in as little as 3-4 weeks (depends on the variety).
