Container growing is especially good for mushrooms due to the ease of controlling the environmental factors that go in producing healthy frequent flushes of high quality fruit. As usual with mushrooms the keys are using a preferred growing medium for the kind of mushroom you want to cultivate and making sure your mycelium get the kind of consistent moisture it needs to grow and thrive. When growing in containers you can also make use of the grain and agar based substrates available for commercial cultivation that we did not cover in this guide.
Watering Your Mushrooms
This is the most important and often the most difficult part of successfully growing plants. There are many factors, including the humidity, temperature, soil type, wind, and amount of direct sun that affect how much and how often water should be applied.
While mushrooms love water, and need it daily, the way water is applied to mushrooms is as important as how much and how often it is given. For best results we suggest daily spraying, or misting with a spray bottle if you are container gardening, to keep the substrate moist without over watering it. Like most plants, mushrooms need air to breath and over watering can delay or even kill your colony just as quickly as allowing things to dry out altogether.
In rainy climates, like the Pacific Northwest, outdoor mushroom cultivation is easier and requires less supplemental watering through most of the year, but your mushroom patch will still need daily watering through the summertime dry season to remain viable and productive. In drier areas permanent irrigation will be required and can be achieved through the use of drip irrigation sprayers. Drip irrigation, especially in a shaded area, is a cost effective and long lasting solution for plants that need frequent water support.
