Mycorrhizal Plant Benefits

Updated: January 3, 2023

Mycorrhizal plant benefits are becoming increasingly popular as gardeners and farmers look for ways to make their plants more resilient and productive. Mycorrhizal fungi form a symbiotic relationship with the roots of plants, providing them with essential nutrients and water, while the plants provide the fungi with carbohydrates. This mutually beneficial relationship results in numerous benefits to the plants. In this article, we will discuss five of the most important mycorrhizal plant benefits as well as answer some frequently asked questions about mycorrhizal plants.

Mycorrhizal Plant Benefits

Improved Nutrient Uptake

One of the most important mycorrhizal plant benefits is an improved nutrient uptake. The root hairs of plants are not able to absorb certain nutrients, such as phosphorus, from the soil. The mycorrhizal fungi form a network around the root hairs, increasing their surface area and allowing them to absorb more nutrients from the soil. This can result in increased growth and health of the plant.

Increased Water Absorption

Mycorrhizal fungi can also improve a plant’s ability to absorb water from the soil. By forming a network around the root hairs, mycorrhizal fungi can increase the surface area that is exposed to water molecules, resulting in increased absorption of water. This can be particularly beneficial in drier climates or during drought periods.

Protection From Pathogens

Mycorrhizal fungi can also protect plants from pathogens. The fungi form a protective barrier around the root hairs, preventing harmful bacteria and fungi from invading the plant’s system. This can result in healthier plants and reduced vulnerability to disease.

Improved Growth

The improved nutrient absorption and water absorption provided by mycorrhizal fungi can lead to improved growth of plants. Plants that have formed a symbiotic relationship with mycorrhizal fungi tend to be larger and healthier than those without this relationship.

Reduced Fertilizer Use

Finally, mycorrhizal fungi can reduce the amount of fertilizer needed for healthy plant growth. The improved nutrient uptake provided by the fungi means that less fertilizer is needed to maintain healthy growth. This can result in significant cost savings for gardeners and farmers.

Frequently Asked Questions About Mycorrhizal Plants


What Are Mycorrhizal Fungi?

Mycorrhizal fungi are a type of symbiotic fungus that forms a beneficial relationship with the roots of plants. The fungi provide essential nutrients and water to the plants, while the plants provide carbohydrates for energy for the fungi.

Are All Plants Suited To Mycorrhizal Fungi?

Most plants are suited to forming a symbiotic relationship with mycorrhizal fungi, however some plants may not benefit as much as others. Soil type, climate, and other factors may also influence whether or not a particular plant will benefit from this relationship.

How Do I Encourage Mycorrhizal Fungi?

Mycorrhizal fungi are naturally present in many soils but may need to be encouraged in order to form a symbiotic relationship with a particular plant species. Adding organic matter such as compost or mulch can help encourage these beneficial fungi in your garden or farm plots.

Can I Buy Mycorrhizal Fungi?

Yes, you can buy mycorrhizal fungi from many gardening stores or online retailers. These products usually come in granular form and must be applied directly to the soil around the roots of your plants in order to form a symbiotic relationship with them.

Are Mycorrhizal Fungi Harmful To Humans?

No, mycorrhizal fungi are not harmful to humans and are actually beneficial for plant health. They should not be ingested by humans though, as they may cause digestive upset if consumed in large amounts.


In conclusion, mycorrhizal plant benefits can be very beneficial for gardeners and farmers looking for ways to make their plants more resilient and productive. Improved nutrient uptake, increased water absorption, protection from pathogens, improved growth, and reduced fertilizer use are just some of the advantages that come with forming this beneficial relationship between plants and mycorrhizal fungi.
