Many gardeners wonder if it is possible to grow mushrooms at home. These curious but tasty fungi are typically grown indoors rather than in the garden, but beyond this, it's certainly possible to grow mushrooms at home. You can purchase mushroom growing kits, but it's also possible to set up your own area for growing mushrooms. Let's learn a little about how to grow mushrooms.

Choosing a Mushroom to Grow

Mushroom growing at home starts with choosing the kind of mushroom you will be growing. Some popular choices when growing mushrooms at home are:

Buy spore or spawn of your chosen mushroom from a reputable dealer (many can be found online). For the purposes of mushroom growing at home, think of spores as seeds and spawn as seedlings. Spawn is easier to handle and grow mushrooms at home. Different mushrooms have different growing mediums. Shiitake mushrooms are normally grown on hardwoods or hardwood sawdust, oyster mushrooms on straw, and white button mushrooms on composted manure.

How to Grow Edible Mushrooms at Home

After you've chosen which mushroom you'll be growing and have attained the preferred growing medium, the basic steps for growing mushrooms are the same. Mushroom growing at home requires a cool, dark, damp place. Typically, this will be in a basement, but an unused cabinet or closet will also work-- anywhere you can create near darkness and control temperature and humidity. Place the growing medium in a pan and raise the temperature of the area to about 70 degrees F. (21 C.). A heating pad works well. Place the spawn on the growing medium. In about three weeks, the spawn will have “rooted,” meaning the filaments will have spread into the growing medium. Once this occurs, drop the temperature to between 55 and 60 degrees F. (13-16 C.). This is the best temperature for growing mushrooms. Then, cover the spawn with an inch (2.5 cm.) or so of potting soil. Cover the soil and pan with a damp cloth and spray the cloth with water as it dries. Also, spritz the soil with water when it is dry to the touch. In three to four weeks, you should see small mushrooms appear. Mushrooms are ready for harvesting when the cap has fully opened and has separated from the stem. Now that you know how to grow mushrooms at home, you can try this fun and worthwhile project for yourself. Many mushroom growers agree that mushroom growing at home produces a better-flavored mushroom than what you'll ever find at the store.
