If you have a garden, a wooded lot, a compost pile, or a sunny area where you can't plant vegetables, you can grow King Stropharia.

This mushroom can perennialize and take resident in your garden soil, coming back year after year if it can find a source of hardwood chips to feed on. King Stropharia tastes earthy, like asparagus cooked in a splash of wine, meaty and delicious. Both the cap and the stem are edible, so don’t trim and toss the stem like other mushrooms! It is called King Stropharia because the mushrooms can get very large, but they are best to eat when young and firm, when the caps are tight to prevent bug infestation.

KING STROPHARIA IS GREAT FOR YOUR GARDEN
King Stropharia (Stropharia rugoso-annulata), also called the “Garden Giant” or “Wine Cap” mushroom, is very good at cleaning soil and water as well. Our chicken house has King Stropharia mycelium threaded through the soil all around it, eating woodchips and straw bedding, forming a mycoremediation barrier for reducing and eliminating coliform bacteria.

Our gardens also have King Stropharia colonizing and enhancing the soil, building and binding the soil together for the plants, unlocking minerals for them, and attracting earthworms that will also contribute their valuable castings to the area.

DON'T HAVE A GARDEN OUR AN OUTDOOR SPACE?
If you don't have a garden, and would like to grow these in your house, just buy one of the 5 lb sawdust spawn bags, open it up upon receipt, and top it with some moist potting soil, about 1 inch deep, close the bag back up with a clothes pin, or some staples, so the moisture is preserved, mist often and then wait. As soon as you see buttons emerging from the soil, mist them to keep moist, so they don’t dry out and shrivel up. One of the easiest mushrooms to grow indoors!
