Instead
of going to the grocery store and paying around $4/pound for
lower-quality, non-organic portobellos, why not just grow them at
home? Follow the instructions below for a step-by-step guide on how
to grow mushrooms: Portobello edition!
Instructions
You
may be surprised to find out that the Portobello is actually just the
mature form of the Agaricus bisporus mushroom, or the White Button
Mushroom. To grow Portobello mushrooms, simply follow the
instructions in my <a href="http://growingmushrooms.blogspot.com/2016/01/how-to-grow-white-button-mushrooms.html">How
to Grow White Button Mushrooms post</a>. Instead
of harvesting all of your white button mushrooms, leave a few behind
to grow to full maturity.
When these mushrooms have reached between 4-5 inches in diameter,
they have become Portobello mushrooms and are ready to become your
next veggie burger.
