Grow chestnut mushrooms at Home!

Growing chestnut mushrooms (Agaricus bisporus) is a multi-step process that includes:

Spawn Production: Chestnut mushroom spawn is produced by inoculating sterilized grain with the mycelium of the mushroom.

This serves as food for the mycelium to grow and multiply on. This step requires around 2-3 weeks, during which temperatures should remain between 75-85degF and relative humidity at 85-90%.

Substrate Preparation

The substrate is the material on which mushrooms will grow. For chestnut mushrooms, this commonly includes a mixture of sterilized wheat straw and horse manure; the wheat straw provides structure while the horse manure provides nutrients.

Prior to seeding your mushrooms, make sure the substrate has been pasteurized to eliminate competing microorganisms and create an ideal environment for their mycelium to colonize.


In this step, spawn is mixed into the substrate and placed into bags. Once sealed, they are incubated at 68-72degF with relative humidity between 85-90% for 2-3 weeks at this temperature/humidity combination. During this time, mycelium will colonize and spread throughout the substrate.


Once the substrate has been thoroughly colonized, a layer of casing material such as peat moss is added on top to create an optimal environment for mushroom fruiting bodies by creating high relative humidity around the substrate and providing water sources for the mushrooms to draw from.


This is the stage when mushrooms begin to form and break through their casing. For optimal fruiting conditions, temperatures should remain between 55-60 degrees Fahrenheit and relative humidity at 85-90%. This period typically lasts 2-4 weeks.

Harvesting and Maintenance

Mushrooms are ready for harvest when their caps have opened and their gills have become visible. Picking should be done manually with a sharp knife, leaving the substrate undamaged.

After picking has been completed, check for signs of contamination on the substrate; take necessary steps to control it. Proper air circulation and humidity management are other essential aspects in maintaining an optimal crop of mushrooms.

It is essential to note that growing mushrooms requires a controlled environment, sterilization techniques and meticulous attention to detail for successful results. If you are new to growing mushrooms, it may be best to start with an established kit or seek guidance from more knowledgeable growers.
