The beneficial bacteria in this microbial inoculant colonize the rhizosphere of your crops. While soil gardens naturally contain myriad microbes that enhance root vigor and boost nutrient uptake, Root Wizard® supplies your soilless garden, which otherwise lacks this microbial life, with bacteria crucial to root function. Designed to increase the bioactivity that bulks up root mass, the plant-symbiotic microorganisms in Root Wizard® help break down organic matter into bioavailable nutrients, so your plants absorb and assimilate more of what they need from plant food for growth, maintenance and flowering.
