How Mushrooms Grow

Mushrooms are naturally grown from spores. But spores are not easy to find. And growing them in this manner takes longer than re-growing mushroom ends. When you use store-bought mushroom ends, the process is quicker because you won’t be relying on spores. You get to use the mycelium that is already on the fungi.

In this case, the mycelium becomes spores. The mycelium bunches up again into primordia to form mushrooms. The primordia and mycelia are found at the stem of harvested mushrooms. When you regrow store-bought mushroom ends, you are actually cloning. And you will reap a bountiful harvest of the parent fungi.

The great news is you only need to learn how to grow Portabella mushrooms from store-bought ones. How can you do that? Let’s look at the step by step guide you can use.

How To Grow Portobello Mushrooms From Store Bought Ones

Growing mushrooms is a simple natural process that can become complex the moment you try your hand on it. Try this easy method below.
  • When growing Portobello, a larger species of mushrooms, you need a sufficiently sized area to grow them. This could be a large plastic or large storage container – at least 4 feet by 4 feet. Prepare your container plus compost, peat moss, and newspaper. Fill your container with compost to a depth of 6 inches.
  • Use any moistened cellulose material for the bedding such as straw, shredded cardboard, or hamster as bedding. Soak the straw for a few days. Pull them out of the container and they are ready for the mushroom ends.
  • Separate the ends from the tops. The ends are fuzzy white where mycelium is stored. Cut them into small pieces before planting them. The best size for store-bought mushrooms is ¼ inch or 6mm. You can use a plastic bin, cardboard box, or paper bags to layer your medium.
  • Place some of the straw or other moist material that you choose at the bottom. Then add the mushroom sliced end pieces.
  • Put another layer until the container is full. The idea here is to keep all the mycelium and medium damp. Also, keep it in the dark with temperatures of 65 to 75 degrees Fahrenheit.
  • Layer a plastic over the box. It must be poked with holes in it. If you use a plastic container, cover it with a lid and poke holes for that air to flow in and out.
  • Mist the medium if it looks dry at the time of planting.
  • In 2 to 4 weeks, the mycelium will be ready to fruit. Cover the medium with plastic to preserve the moisture and allow the fungi to keep growing. In about 19 days, harvest your mushrooms.
This is as easy as 1, 2, 3!
