Portobello mushrooms can be grown.

Portobello mushrooms are easy to grow.Purchase a kit to make the process simpler.Plant portobello in the planting bed if necessary.If you grow the mushrooms indoors or outdoors, make sure the soil is damp and at the right temperature.You will soon be able to add mushrooms to a hamburger or salad.

Step 1: Use scrap wood to build a tray frame.

Purchase boards from a home improvement store or pick up some scrap wood at a lumberyard.The frame should be at least 20 cm deep and 15 cm long.The bed can be formed by nailing the wood together.Mushroom-growing kits can be purchased from a gardening store or online.It includes everything you need to grow mushrooms.

Step 2: The bed should be filled with compost.

Purchase a bag of compost from a gardening center and pour it into the bed.If you fill up the tray, you won’t have enough room to mix the soil and moss.It shouldn’t stink up your house because the manure is dried.You can use other organic compost products instead of manure-based compost.

Step 3: When growing portobellos outdoors, cover the bed with black plastic.

Put a piece of cardboard over the compost.You can find a black plastic sheet at a general store or home improvement store to cover the cardboard.It shouldn’t get blown away by the wind if it’s tight inside the bed.sterilizing the soil won’t be necessary if you grow your portobellos indoors.If you want your mushrooms to grow big and healthy, you can still do it.

Step 4: When growing outdoors, leave the bed in the sun for two weeks.

Let the bed sit out in the sun and leave the plastic in place.The compost of harmfulbacteria that can damage the mushrooms will be cleared by the sunlight through the plastic and cardboard.

Step 5: Portobellos can be grown in a dark room.

The tray should be placed in a dark corner of a shed, closet, basement or another suitable area.The temperature in the dark room should be between 50 and 70 F.The temperature won’t need to be adjusted because you’re working indoors.

Step 6: The bed should be moved to a climate-controlled area.

In the daytime, the temperature needs to be no higher than 21 C and in the night, no lower than 50.You may need to move the bed to a safer location if the temperature goes past this.It is important to get the temperature right, but a dark area in the shade of a tree can help.The bed can be used to monitor the soil.Rain falling on your planting bed is okay because mushrooms do well in water.

Step 7: The mushrooms should be put into the compost.

Mushroom spores can be found at some gardening stores.Put on a pair of rubber gloves once you have them.After sprinkling the spores onto the compost, gently mix them with 2.5 cm of compost.When you are done, press down on the compost.If you used the plastic and cardboard to sterilize the soil, first remove it.

Step 8: Peat moss and newspaper should be used to cover the compost.

Peat moss can be found at a garden center or home improvement store.Spread a layer over the compost.The newspaper should be spread over the moss.

Step 9: The newspaper should be Misted daily to keep it moist.

The newspaper should be kept wet with a spray bottle at least once a day.It’s a good idea to spray it if it looks dry.It is unlikely that you will supply too much water by mist.Mist the bed twice a day to make sure it doesn’t dry out.

Step 10: If the mushrooms are growing, remove the newspaper.

Lift up the newspaper after 2 weeks.There are small, white heads coming out of the moss.The newspaper should be left off if they are there.The mushrooms are taking root if you see white streaks in the soil.For another week, keep the newspaper in place.

Step 11: As the mushrooms grow, continue to mist them.

Water drips into the bed if the moss is misted every day.If you want, you can harvest the mushrooms sooner than 10 days after they are fully grown.

Step 12: When the caps are fully unfurled, remove the portobellos.

Portobellos peak when the mushroom caps are about 6 cm in diameter.They should be put in a brown paper bag in the refrigerator and washed with a damp paper towel.If you harvest the mushrooms early, you will be eating brown criminis instead of portobellos.Wait until the edges of the caps are flat.

Step 13: When new mushrooms form, repeat moistening the compost.

For now, keep your tray intact.Once white streaks form again, add a new layer of newspaper.If you follow the same steps, you will usually get 2 or 3 batches of mushrooms.
