Mycorrhizal Fungi: Unseen Hero Massively Benefits Lawns

Unlock the secrets to a flourishing lawn by becoming a mycorrhizal maestro! Discover how simple turf management practices can amplify the performance of these underground heroes. From the rhythmic aeration dance to the precision choreography of mowing heights, each move impacts mycorrhizal activity. Explore the delicate balance of watering as the conductor orchestrating growth, avoiding overwatering drown-outs or underwatering desolation. Navigate the fertilization symphony cautiously, avoiding the overpowering notes of excess nutrients that can mute mycorrhizal harmony. Finally, embrace the grand finale with compost topdressing—a nutrient-rich encore that nourishes both grass and fungi, creating a stage where mycorrhizal networks thrive. Elevate your lawn care routine and witness the magical symphony of mycorrhizal activity unfold!


What is Mycorrhizal Fungi?

Mycorrhizal fungi are the white silk branches found within soils that attach to rooting plants. These microscopic organisms extend their fine hyphal networks into the soil, literally extending the reach of roots zones and tapping into a treasure trove of nutrients that would otherwise be inaccessible. In this underground ballet, mycorrhizal fungi benefit your lawn's ability to withstand stressors and recover swiftly with this added reach, creating a resilient green haven. Acting as nature's nutrient couriers, these fungi establish a harmonious exchange, receiving sugars from the plant in return for vital minerals. As the unsung heroes of soil health, mycorrhizal fungi contribute to the flourishing dance of life beneath the surface, ensuring a vibrant and thriving ecosystem for your lawn to call home.

What you can do to help mycorrhizal use and performance in your lawn

As outlined above, mycorrhizal fungi does help your lawn withstand stressors and, when affected by those stressors, helps it rebound more quickly. So it makes sense to help out of fungal friends where ever we can.


You can positively impact your mycorrhizal community by completing the following turf management practices:

  • Complete Aerations Regularly

  • Mow regularly and at recommended heights

  • Manage water inputs to provide adequate H2O without overwatering

  • Apply fertilizers responsibly

  • Apply compost topdressing



Mycorrhizal Activity Impact: Aerating

Soil aeration is the act of punching holes in the soil surface to facilitate air and nutrient transfer between the atmosphere and soil. The channels created through this process serves as a breath of fresh air to mycorrhizal activity. With improved water and nutrient transfer into the soils, mycorrhizal fungi can more efficiently extend their hyphal networks with in turn maximizes their contribution in the symbiotic relationship that exists between the fungi and plant.


Mycorrhizal Activity Impact: Mowing

The seemingly simple act of adjusting your lawn mower's height holds the key to creating an optimal environment for mycorrhizal fungi. When we mow too short, we inadvertently disrupt the natural balance. A taller grass canopy acts as a shade, preserving soil moisture and moderating temperatures. This not only prevents the soil from drying out but also creates a cooler, more hospitable space for mycorrhizal fungi to thrive. Additionally, a taller grass height fosters better air circulation through the canopy and down to the soil, providing the ideal conditions for mycorrhizae to extend their hyphal networks. So, the next time you adjust your mower, consider it a choreography for mycorrhizal success, sculpting a stage where moisture, airflow, and temperatures harmonize for a flourishing lawn.


Mycorrhizal Activity Impact: Watering

In the delicate dance of lawn care, watering practices emerge as the choreographer for mycorrhizal growth. Striking the right balance is crucial, as both overwatering and underwatering can disrupt the harmonious rhythm. Overwatering saturates the soil, limiting the oxygen supply essential for mycorrhizal fungi. This excess moisture can drown these beneficial organisms, hindering their ability to form symbiotic relationships with plant roots. On the flip side, underwatering deprives mycorrhizae of the necessary moisture for survival and function. Maintaining a mindful watering schedule that aligns with the specific needs of your lawn ensures a conducive environment for mycorrhizal growth. It's the fine-tuned coordination between hydration and moderation that orchestrates a symphony of mycorrhizal harmony, contributing to the overall vitality of your lawn.


Mycorrhizal Activity Impact: Fertilizing

Its common to want a greener lawn than the neighbor. Beware of over-fertilizing. Though well-intentioned, too much can inadvertently sabotage the intricate dance of mycorrhizal fungi beneath the surface. Excessive fertilization disrupts the natural nutrient balance in the soil, rendering mycorrhizae less effective in their role as nutrient facilitators. The surplus of nutrients can lead to a diminished need for the symbiotic relationship between these fungi and plant roots, hindering their ability to enhance nutrient absorption. It's a delicate equilibrium – providing the necessary nutrients without overwhelming the system. Striking this balance ensures that mycorrhizal activity remains a vital force in promoting a resilient and thriving lawn.


Mycorrhizal Activity Impact: Compost Topdressing

Topdressing is the practice of applying a thin layer of material to a lawn. In this case compost is recommended. Compost contains a feast for both grass and mycorrhizal fungi. It also includes plenty of mycorrhizal fungi strains to revitalize colonies that may be reduced or non-existant. The organic matter in compost serves as a buffet of essential nutrients, encouraging the proliferation of mycorrhizae and enhancing their symbiotic dance with plant roots. As the compost settles into the soil, it acts as a slow-release nutrient source, fostering a sustained environment where mycorrhizal networks can flourish. Compost topdressing not only nourishes the visible greenery but also lays the groundwork for a robust and resilient lawn, where mycorrhizal harmony takes center stage.


In cultivating a resilient and thriving lawn, nurturing the symbiotic dance between roots and mycorrhizal fungi becomes paramount. The impact of thoughtful turf management practices, from regular aerations to mindful mowing heights, showcases a profound influence on mycorrhizal activity. With each act, we enhance the breath of fresh air mycorrhizae receive, optimizing water and nutrient transfer for the benefit of the entire ecosystem. Watering becomes a delicate choreography, avoiding the pitfalls of over- and underwatering, ensuring a harmonious environment for mycorrhizal growth. Fertilizing, though tempting for a greener lawn, demands moderation to sustain the intricate balance required for mycorrhizal vitality. The grand finale, compost topdressing, provides a feast for both grass and fungi, laying the foundation for a robust, resilient lawn where mycorrhizal harmony takes center stage. By embracing these practices, you become the conductor of a symphony, orchestrating the flourishing dance of life beneath the green tapestry of your lawn.
