Mycorrhizae Treatments

What is Mycorrhizae?

Mycorrihizae [myco means fungus and rhiza means root] is a root structure formed when a certain type of fungus attacks the roots or certain plants. The fungus and young lateral roots form a symbiotic relationship, creating Mycorrihizae. This bond makes for healthier, more vigorous plants, especially when the plants are under stressful conditions. Urban settings are often lacking in Mycorrihizae and less fertile soil that forest conditions. Also, Mycorrihizae can help trees that are stressed due to mechanical damage such as from construction.

There are two types of Mycorrihizae: ectomycorrhizae and endomycorrhizae. Ectomycorrhizae grow around and inside the cells in the cortex (an outer layer of tissue in the tree) of the short lateral roots and form a sheath around the roots. Endomycorrhizae actually invade the individual cells of the cortex, existing completely inside the tissue, and do not form a sheath. The invasion of cells from either type of tissues of the cell, where it could cause more harm. Endomycorrhizae are found on many types of plants, but these do not include many species. Ectomycorrhizae are found on many types of plants, but these do not include many species. Ectomycorrihizae are found almost entirely on trees, attacking very few other species of plants.

The symbiotic relationship (two or more organisms relying on each other for survival) between Mycorrihizae and roots has many benefits for both. The Mycorrihizae enhances the nutrient uptake of the roots. This is very important in infertile soil. This increased nutrient uptake is possible due to Mycorrihizae sending out fungal strands that explore in the soil, increasing the surface of roots in contact with soil, as well as absorbing the nutrients that are normally unavailable to roots. They Mycorrihizae also helps the plant by decreasing infection by some soil borne pathogens. Some types of Mycorrihizae may release toxins as well as the sheath forming a physical barrier. In turn, the plant gives the Mycorrihizae energy in forms like carbohydrates. Mycorrihizae reproduce by spores that are spread by the wind. However, they must have their host plant in order to survive.

What Can ArborCare Do For Me?

Our educated arborists understand that relationship between Mycorrihizae and trees. Most urban settings have a lack of the Mycorrihizal fungi. Therefore, we do offer a Mycorrihizae treatment. We apply this as a soil injection. We include some fertilizer in this treatment to encourage the bond to form. Call us at (801)-972-8733 with any other questions or for more information.
