Waiting too long to harvest, hoping mushrooms will grow bigger. It’s a common misconception—letting mushrooms stay on the beds longer will increase your harvest. But in reality, overgrown mushrooms drain nutrients from the substrate and reduce future flushes.

Here’s the golden rule:

Harvest white button mushrooms just before the veil breaks—when caps are still firm, round, and closed.

Pro Tip: Check beds at least twice daily during peak growing periods. Even a delay of a few hours can make a difference!
