How to Grow Button Mushrooms

Button mushroom growing is becoming a popular part of gardening today. It's not as common as growing tomatoes and green beans, but it has become an important part of the home gardener's arsenal and for good reason.

Mushrooms are one of the easiest types to grow. They don't need sunlight and you can buy simple, affordable kits to help you grow them. Hobbyist farmers find that growing mushrooms is also a great way to earn some extra money.

Unlike some varieties of mushrooms, button mushroom spores are easy to find and are some of the most versatile mushrooms in the kitchen. Perfect for soups, stir-fries, chicken dishes, and served over steaks.

Are you still hungry? Supermarket mushrooms are delicious, but homegrown mushrooms are on another level. Ready to learn how to grow button mushrooms successfully? Let's dig.

1.Choose a location

Mushrooms like to grow in cool, dark areas, so you should choose a place to grow them that is between 65 and 75 ℉. It must also be protected from light and any disturbance.

Many mushroom growers choose a basement or liner to grow their white mushrooms. If you live in an apartment, dark cabinets work too.

2.Find Spawn

You need to use spawning, not seeds, to grow mushrooms. You can buy ready-made spores online or at a nursery. Some spores have already been inoculated or mixed with a substrate such as soil, hay, or sawdust.

3.Increasing supplies

Growing mushrooms is not the same as growing tomatoes or peas. It requires some supplies that you may not use regularly, so you need to prepare ahead of time.

A box:

A cardboard box works well as long as it is at least 6 inches deep and approximately 14 inches by 16 inches. You need a box with a lot of surface area for the mushrooms to grow.

If you don't have cardboard, you can use wood. The boxes can also be made of plastic or metal, depending on what you have available.

Trash Bag:

A trash bag is used to line the cardboard box to keep things from getting dirty while keeping moisture in place.

Composted manure:

Composted manure is the perfect growing medium for your white mushrooms as it is also a food source for them.

White mushrooms grow well in nitrogen-rich manure, such as cow or horse manure. If you don't have 100% manure, equal parts compost and manure work too.


The newspaper keeps mycelium moist as it spreads and grows through the medium.


Don't make the mistake of growing mushrooms only in composted compost. Mix the manure with a little vermiculite.

The manure provides nutrients to the fungi and the vermiculite provides aeration and moisture retention.

4.Caring for mushrooms


Button the mushrooms as a warmer spawning medium, so if the compost gets too cold, place the tray on a hot pad to bring the temperature to 70 ℉. You shouldn't heat the soil any more than that, because it can kill spores.


You should check your mushrooms once a day to make sure the newspaper is damp. If not, spray gently with more water. Never pour water into the compost mix or onto the paper, or you will create wet patches that are not the right consistency to stimulate mycelium growth.

Add casing

In three weeks, you should see a white web of mycelium spreading over the manure and vermiculite mixture. Once you see the mycelium, remove the heating pad.

Then take more of the 50/50 mixture of manure and vermiculite and cover with an inch of the mixture. This part is called callus addition and is necessary to stimulate fungus growth.

You can also mix pieces of peat and soil or peat and chalk. Spray with water to moisten everything. Remember not to add water! Re-cover with plastic.


Check once a day to make sure the medium is moist and spray if necessary. Wait another 3-5 weeks and your white mushrooms should start to grow.

Once fungi start to form, continue spraying the soil and keep it moist.
