Mycorrhizal Fungi: Tree & Shrub Care

Share this post:

I have heard that mycorrhizal fungi are beneficial to trees and shrubs. Exactly what are mycorrhizal fungi? Mycorrhizal fungi will either grow into or on the surface of plant roots. There is a mutually beneficial relationship that develops between the roots and mycorrhizal fungi. The roots supply a steady supply of carbohydrates to the fungi to help them to grow, and, who in return, provide water and minerals to the roots. Some essential plant nutrients, such as phosphorus, are very difficult for plants to access from the soil. Mycorrhizal fungi are fairly efficient at accessing this nutrient and can make it available to the plant roots. It is a symbiotic relationship that benefits many plants.
