How Mushrooms Grow?

Mushrooms🍄 are interesting species that have grabbed human curiosity for centuries owing to their distinctive look and cooking importance. But have you ever been curious about how mushrooms grow?

From spore germination through fruiting body development, the entire procedure of mushroom growth is extensive & complex, including several stages.

In this article📃, we’ll discuss the various stages of mushroom development, factors affecting mushroom growth & the cultivation and harvesting of various varieties of mushrooms.

How mushrooms grow?

Introduction to Mushrooms

Mushrooms are a form of fungus that comes in a variety of sizes & shapes. They may be found in woods, farms & even dead trees.

Mushrooms are a great provider of nutrients that have been used for thousands of years to treat a variety of illnesses.

How Mushrooms Grow

Spores are the first stage of the life cycle of mushrooms. These spores are produced by the mushroom & may be transported to a suitable growth environment by wind or other methods.

After landing on an appropriate substrate, the spores start to germinate.

Stage 1: Spore Germination

The 1st stage of mushroom development is spore germination.

When spores settle in a favorable environment, they germinate and produce the hyphae which create mycelium.

Mycelium develops & expands throughout the substrate, collecting nutrients & decomposing organic waste.

Factors that Affect Spore Germination:

Numerous factors, like humidity, temperature🌡️ & the availability of nutrients, may affect spore germination.

Like, the majority of mushrooms need a temperature range between 18 to 25 °C (65 to 80 °F) and high levels of humidity to germinate properly.

Stage 2: Mycelial Growth

The 2nd stage of mushroom development is mycelial development.

Mycelium creates a system of white threads that infiltrate the substrate as it develops & expands.

This may take anything from a few weeks to a few months, based on the species of mushroom & climatic circumstances.

Substrate Preparation:

Mycelium develops on the substrate, hence its preparation is essential for optimal mushroom production.

Depending on the variety of mushrooms being produced, the substrate might vary, but it is often a combination of organic waste like straw, sawdust, & compost.

Stage 3: Primordia Formation

The 3rd stage of mushroom development is the production of primordia.

As the mycelium achieves maturity, primordia, which are little mushroom pegs, start to grow on the substrate’s surface.

Primordia development is induced by environmental objects like humidity, temperature, & light.

Environmental Factors that Trigger the Formation of Primordia:

Many environmental conditions, like humidity, temperature, light, & levels of carbon dioxide, may impact primordia production.

For example, most mushroom primordia need temperatures between 16 to 23 °C (60 to 75 °F), high levels of humidity & appropriate light.

Stage 4: Fruiting Body Development

The fruiting body is the 4th & last stage of mushroom development.

This stage starts with the production of microscopic mushroom pegs, which over the course of many days to weeks develop into complete fruiting bodies.

Harvesting and Yield:

Mushrooms are normally harvested when their fruiting bodies reach maturity and just before the veil behind the cap opens.

Depending on the species of mushroom, the substrate utilized, & the growth circumstances, the yield might vary.

Factors Affecting Mushroom Growth

A lot of factors affect the development of mushrooms. Below are the most important factors include: 👇

1. Temperature

Mushrooms thrive in wet, cool🥶 environments. The temperature may have a substantial effect on mushroom growth & development.

2. Humidity

Humidity is another crucial component in mushroom development. To grow effectively, mushrooms need high levels of humidity.

3. Light

Although mushrooms don’t need light🌞 to thrive, it might affect their development & growth. Certain types of mushrooms may need light in order to get started in the fruiting stage.

4. Nutrients

For development, mushrooms need a substrate and a nutrition supply. The substrate may be comprised of a range of substances, including straw, sawdust, & even compost.

Common Types of Mushrooms

There are several varieties of mushrooms & each has its own specific growth needs. A few of the most popular varieties of mushrooms are shown below: 👇

1. Button Mushrooms

Button mushrooms are among the most popular mushroom varieties. They are commonly cultivated in composted manure & need temperatures between 55 to 60 °F (12 to 15 °C) to thrive.

2. Shiitake Mushrooms

Shiitake mushrooms are a common ingredient in Asian recipes. They are often planted on wood & need temperatures between 65 to 75 °F (18 to 24 °C) to thrive.

3. Oyster Mushrooms

Oyster mushrooms are tasty, delicate mushrooms, which are widely used in stir-fries & soups. You can cultivate them on sawdust or straw and need temperatures between 70 to 75 °F (21 to 24 °C) to thrive.

Cultivating Mushrooms

You can see mushrooms thriving in the wild, as well as you may develop them in your house🏠. Mushroom cultivation needs particular expertise & equipment.


You require a substrate, spawn & a growth container to develop mushrooms. You can use straw, sawdust & even coffee grounds as the substrate.

Also, you can use the mushroom counterpart of seeds, spawn to initiate the growth process.


For growing mushrooms, you must first create the substrate and spawn, then cover the substrate using the spawn & give the proper growth conditions.

This may involve regulating the proper humidity levels & temperature, providing sufficient ventilation, and making sure the growth container is clean and sanitary.

Harvesting Mushrooms

You can harvest mushrooms after they achieve maturity. The harvest date will vary depending on the mushroom variety you cultivate & the growing conditions.

1. Harvesting Button Mushrooms

You can harvest the Button mushrooms once the caps develop completely & have split from the stem. You can collect them prior to the caps opening & releasing spores.

2. Harvesting Shiitake Mushrooms

You can harvest Shiitake mushrooms once they grow completely with a small concave shape on the caps. It is advisable to harvest them before the outer edges of the caps begin to curl upwards.

3. Harvesting Oyster Mushrooms

You can harvest the Oyster mushrooms after the caps grow completely & have a little curling edge. You need to harvest them prior to flattening their caps.


Mushrooms🍄 are different and interesting organisms with a distinctive growth process.

Learning how mushrooms grow will help you know the effort required to produce this tasty & nutrient-rich fungus.

Whether you are cultivating mushrooms in your house🏠 or just using them in your beloved recipes, it is essential to understand the delicate process involved in their development.

What is the process of mushroom growth?

Mushrooms grow through a process called mycelium growth, where the spores of the mushroom form thread-like structures called mycelium, which absorb nutrients from the soil.

What are the ideal growing conditions for mushrooms?

Mushrooms grow best in a cool, dark, and damp environment, with a temperature range between 55 to 65 °F, and high humidity levels of 70 to 90%.

How long does it take for mushrooms to grow?

The time required for mushroom growth varies based on the variety of mushrooms & the environment under which it grows. It might take between a few weeks to months.

Can I grow mushrooms indoors?

Yes, you can cultivate mushrooms inside but you must give them proper growth conditions.

How do I cultivate mushrooms at home?

You can cultivate mushrooms at home using a grow kit or by growing them from spores, which requires a substrate, such as compost, straw, or sawdust, and a growing container.

How much water do mushrooms need to grow?

Mushrooms require a high level of moisture to grow, typically needing 2 to 3 times their weight in water.

What are the common types of mushrooms grown for consumption?

Common edible mushroom types include button, shiitake, oyster, and Portobello mushrooms.

Are all mushrooms safe to eat?

No, not every mushroom is edible. Certain mushrooms are toxic & may be fatal if ingested.

How do mushrooms reproduce?

Mushrooms reproduce through spores, which are released from the cap of the mushroom and carried by wind or animals to new growing areas.

Can mushrooms grow in different types of soil?

Yes, mushrooms can grow in various types of soil, as long as they have access to nutrients and moisture.

Are mushrooms easy to grow?
