How to grow oyster mushrooms (planting)

  • Cut the wheat straw into smaller pieces of around 1-3 inches in length (Approximately 3-8 cm in length). 
  • Steam the straw in a drum of water to temperatures of between 70-75 degrees celcius for 40-45 minutes. Steaming is a form of sterilization /sterilization that helps to kill the bacteria and other fungi. (Note: Steaming means there is a gap between the substrate and the boiling water, else you will be boiling the substrate.)
  • Once you have pasteurized the straw, take it out of the heating pot and let it sit in a clean area while it cools down. 
  • Once the straw has cooled down, ensure that the straw should not be dripping wet but should still be dump from the pasteurization then pack the straw in your plastic bags tightly and then distribute some of the mushroom seeds throughout the straw.
  • Close the mouth of the bags with a zip tie or rubber band then sterilized cotton wool to allow in air and the bag to breathe.
  • Now take your bags to incubation in your grow house. They grow best between 15-20 degrees celcius.
  • Now you wait for the mushroom spawn to develop into mycelium (white furry cobwebs) and start taking over the entire bag. This takes a number of weeks 2-3 weeks.
  • Your bags should stay moist but not dripping wet. Spray some water if required.
  • About 4 weeks later, the mycelium should have spread across the entire bag of straw and your mushrooms should start forming.
  • Cut some holes in the bags to allow the mushrooms to come out in clusters.
  • Mist them with water 2 or 3 times a day. Ensure its not dripping wet, just moist.
  • Once the mushrooms are ready to harvest, give them a twist at the base. This ensures that you leave the mushrooms on the bottom still on the bag as its needed for subsequent flushes of mushrooms.
  • If you keep the mushrooms moist and in suitable conditions, you should get 3-4 flushes of mushrooms.
  • When your bags stop producing the straw can be used as mulch in the garden.
