How To Grow Mycorrhizal Fungi?

Mycorrhizal fungi play a vital role in enhancing plant health and nutrient uptake. Forming a symbiotic relationship with plant roots, these beneficial fungi aid in water absorption, mineral absorption, and overall plant growth. Cultivating mycorrhizal fungi is a straightforward process that can significantly improve your garden's productivity and environmental sustainability. Now, we will guide you through the steps to grow mycorrhizal fungi effectively.

Choose the Right Host Plant

Selecting the appropriate host plant is crucial for successful mycorrhizal cultivation. Mycorrhizal fungi establish a symbiotic relationship with various plants, but some species prefer specific hosts. Common mycorrhizal host plants include tomatoes, beans, peas, and most fruit trees. Choose a plant that suits your garden's needs and climate, as it will encourage the growth of compatible mycorrhizal fungi.

Prepare a Suitable Growing Medium

Mycorrhizal fungi thrive in a loose and well-draining growing medium. A mix of compost, peat moss, and vermiculite or perlite works well. Make sure to sterilize the medium to prevent any harmful pathogens from interfering with the growth of the fungi.

Obtain Mycorrhizal Inoculants

You can buy mycorrhizal inoculants from garden centers or online suppliers. These inoculants contain spores or mycelium of beneficial mycorrhizal fungi. Make sure to choose a product that matches the host plant you selected in Step 1.

Inoculation Process

Drench the roots of your selected host plant with the mycorrhizal inoculant before transplanting it into the growing medium. Ensure the inoculant comes into direct contact with the plant's roots to establish the symbiotic relationship effectively.

Proper Plant Care

Maintain optimal growing conditions for your host plant to facilitate mycorrhizal colonization. Regular watering, appropriate sunlight, and nutrient-rich soil will encourage the fungi to flourish.

Avoid Excessive Chemical Fertilizers

Mycorrhizal fungi assist in nutrient absorption for plants. Reduce the use of chemical fertilizers, especially those containing high levels of phosphorus, as they can hinder mycorrhizal development.

Patience and Observation

Mycorrhizal colonization takes time. Be patient and observe your plants' growth over several weeks to notice the positive effects of the mycorrhizal fungi. You will likely witness improved plant vigor, enhanced root development, and increased resistance to stressors.


Cultivating mycorrhizal fungi is a simple yet powerful method to improve plant health and overall garden productivity. By choosing the right host plant, providing a suitable growing medium, and using mycorrhizal inoculants, you can establish a thriving symbiotic relationship between your plants and these beneficial fungi. The benefits of mycorrhizal fungi are vast and extend beyond what we covered here. So, embrace this natural gardening technique, reduce chemical inputs, and watch your garden flourish in a more sustainable and eco-friendly way. Happy gardening!
