Morel hunters can spend many hours in the woods peering under fallen trees and leaf piles looking for the elusive mushroom. However, mushroom hunters run the risk of mistaking poisonous mushrooms for edible varieties. Though it takes several seasons for morel mushrooms to grow, cultivating them at home eliminates the uncertainty of hunting. Wait to prepare your growing site until you receive your kit in the mail, because growing instructions are specific to each individual spawning kit.
Prepare the site for growing your mushrooms. Find a shady area with well-draining soil and remove all weeds including grass. Check your spawning kit for exact dimensions.
Mix equal parts gypsum, peat and wood ash into the top 4 to 6 inches of soil. Freshly cooled ash from wood burned in the last 24 to 48 hours works best.
Inject morel spores into the soil by following the directions on your spawning kit. Spores are usually left in coarse chunks and mixed into the top 2 inches of soil.
Spread spawn directly on top of the prepared soil in the manner detailed by your spawning kit.
Cover half of the growing site with elm logs. Logs should be cut in early winter from healthy trees about 4 feet long and 3 to 8 inches in diameter.
Monitor the moisture content of your planting site. Your spawning kit will detail water requirements, but it is important to remember that morel mushrooms require high humidity. Keep water on hand and add moisture as needed, especially during periods of low rainfall.
Care for your morel mushroom site through two complete growing seasons. After the second growing season, morel mushrooms should begin to grow and reproduce. Once established, the sites can continue to produce mushrooms for up to 20 years!
