The preparation of mushroom beds is a crucial step in successful mushroom cultivation. To begin, select a suitable location with controlled humidity and good ventilation. The chosen substrate, such as sawdust, straw, or agricultural waste, should be sterilized thoroughly to prevent contamination and promote healthy mushroom growth. Layer the substrate in a clean, level area, ensuring proper moisture content throughout. Properly prepared mushroom beds provide an ideal environment for the mycelium to colonize and mushrooms to fruit, ensuring a bountiful harvest.
