Morel mushrooms come into season in the spring in most regions. The temperature, substrate and humidity must be controlled for morel mushrooms to grow indoors. They prefer humid, moist conditions to bloom and thrive. They are hunted in the wild growing along mycelium. This web-like root system grows along the ground, just under the surface.
Choose a potting location that is moist, warm and dark or shaded. Select a planting tray 1 to 2 inches deep and narrow.
Fill the planting tray with substrate. Humus, compost or hay can be used as a substrate for morel mushrooms.
Place mycelium in the tray and lightly cover with substrate.
Maintain moist, dark conditions until the mycelium begins to fruit.
Allow mushrooms to turn brown before harvesting. The caps will turn gray first, but they are not ripe enough for harvesting.
