This is the final ingredient to the root dip solution. Soil Moist is a potassium-based (pH neutral) polymer designed specifically for the horticultural industry. Mix the granular fines with water to create a safe, non-toxic root dip slurry which is very effective in reducing transplant shock. This gel mixture attaches to the dipped roots to increase the water holding capacity while plants are being established. One 85 gram packet mixed with 15L of water will treat 10-20 tree/shrubs.
