MYKE is an all-natural fungi inoculation for trees and shrubs. The technical term for these fungi is called mycorrhizae. These fungi attach to the root hairs and its hyphae or tendrils extend out into the soil at the microscopic level. Their job is to harvest water and minerals and bring it back to the tree to consume. In essence, mycorrhizae can quadruple the root system of trees and shrubs making for superior growth! Mycorrhizae are integral to all trees and shrubs the world over. Unfortunately, the fungi that supports sagebrush isn’t the same for example, as maple trees, that’s why we recommend MYKE. You are guaranteed inoculation. We sell MYKE in the 1.4 QT (6 cups) and the 3.6 QT sizes (16 cups). In most cases, the recommendation is to use between 2 and 4 cups per tree and shrub. Simply coat the root ball and the surrounding planting hole with MYKE. For more information check out MYKE’s website.
