Grow homegrown mushrooms from seed with pre-inoculated mushroom logs. To grow mushrooms, just place the pre-inoculated mushroom log in a fully shaded area of your garden or landscape. Make sure the log is sitting where snow or rain will fall on it. If rainfall is inadequate, water the mushroom log regularly. Then, enjoy your harvest of homegrown mushrooms. Our mushroom logs will keep producing for 4-6 years or longer. When selecting mushroom logs to buy online, consider their space requirements and light needs. Then select the type of mushrooms you'd like to grow. Some popular choices are the flavorful Shiitake and the eye-catching Lion's Mane.
