Greatly increase the absorptive surface area of root systems

Down To Earth™ Soluble Root Zone is a powerful blend of thirty species of beneficial soil organisms that colonize plant roots and expand into the surrounding soil to greatly increase the absorptive surface area of root systems. Mycorrhizal fungi, Trichoderma and a diverse mix of bacterial species work symbiotically to promote improved soil structure and enhanced root growth. Soluble Root Zone is ideal for inoculating all types of plants and establishing biological diversity in garden soils, potting mixes and soilless media.


The objective is to ensure physical contact between the roots and the inoculant

Soluble Root Zone can be watered in to porous media in gardens, seed beds or propagation trays or applied directly to seeds, roots and cuttings when transplanting. The objective is to ensure physical contact between the roots and the inoculant.

Vegetable Gardens & Flower Beds:  Mix 2 teaspoons per gallon of water for use as a soil drench for established plants. Water in newly planted seedlings and transplants at the same rate or saturate root balls just before planting.

Trees, Shrubs & Vines:  Mix 4 oz in 50 gallons of water. For new plantings, saturate root balls or cuttings just before backfilling. For established plants, drench or inject into surrounding soil to encourage deep root inoculation.
