Growing mushrooms outdoors in beds is a sustainable and easy method of adding tasty crops to your garden. Choose mushroom types such as oyster mushroom, blue knight's hat, or wine cap, which thrive in your local climate. To prepare the bed, choose a shady spot and use organic material such as straw and wood chips. Inoculate the substrate with fungal spawn and maintain even humidity. Ensure maintenance by monitoring temperature and humidity, and remove any competing vegetation. Harvest the mushrooms when they are fresh. Planning your cultivation to take advantage of seasonal moisture changes, as well as proper maintenance and selection of mushroom types, will ensure a large harvest. Good luck with the cultivation!
