Reishi is considered beneficial for good health and a long life in Asia. It has been referred to as the mushroom of immortality. Reishi also carries the name Ling Chi in China, where it has been used medicinally for at least 1,000 years. Reishi mushrooms grow on old trees, and most often can be found in the mountains of Korea, Japan and China. You can also grow reishi mushrooms at home by inoculating a log with the spawn.
Cut a 4-foot long and 14-inch diameter log from a hardwood tree in late winter or early spring. Select trees such as aspen, sugar maple, oak, poplar or birch to obtain your log from. Make sure you cut your log from a healthy tree.
Wait at least 3 weeks after cutting your log to inoculate it with reishi mushroom spawn in the spring after the last frost. This allows enough time for anti-fungal compounds within the tree to disappear.
Select a shady, moist area in your yard to begin your mushroom patch. Dig a 4-foot-wide trench in your garden area. Dig the trench to a depth that is half the height of your log. Wedge the log into the trench, and push the soil around the sides of it.
Use a 5/16-inch drill bit in your drill, and begin drilling a row of 2-inch-deep holes along the log. Space the holes 4 inches apart.
Drill a new row of holes 4 inches from the last row so that the row is offset. Continue to make new rows until you have 30 to 50 holes in your log.
Place the first spawn plug in a hole, and use your hammer to secure it into place. Hammer the rest of the spawn plugs into the remaining holes.
Melt your beeswax in a double-boiler over medium heat. Dip your paintbrush into the melted wax, and brush it over each hole to seal the plug.
Add enough water each day to moisten your log. Cover your reishi mushroom log with clear plastic to keep the humidity high. Your mushrooms will develop in 6 months to 1 year.
