How Long Does It Take a Mushroom to Grow?

Most mushroom varieties produce the first fruits within 10 days. Mushrooms continue to reproduce after they are harvested, and growers can harvest up to three times in a three-month period.

Crimini, portabello and white button mushrooms take up to a week longer to produce the first fruits, but they yield more mushrooms over time. Shiitake mushrooms can be harvested every two weeks over a three-month growing season. Harvested mushrooms should be sealed in a paper bag that is stored in the refrigerator. Most mushroom varieties stay fresh for up to seven days, although shiitake mushrooms last up to two weeks in the refrigerator.
