Roots PHC Tree Inoculation Program

Principle: Extensive research has proven that the presence of abundant mycorrhizae and beneficial rhizosphere bacteria greatly improves the survival, growth rate, and disease resistance of plants compared to plants lacking these. This is particularly true for plants growing in stressed or degraded sites, urban environments, drought conditions, and compacted soils. The following treatment program combines these beneficial microbes with micronutrients, slow-release fertilizers, and organic soil conditioners to improve transplant survival and long-term health of trees and shrubs.
