Bio-Green is a concentrated blend of chelated micronutrients recommended for use on all turf, ornamentals, vegetables, trees, shrubs, and flowers. There are at least 16 basic nutrients required for optimal plant health. Missing nutrients can cause stress and even death. Factors such as pH, high phosphorous, salts, or other imbalances can tie up nutrients and affect availability. Regular application of Bio-Green will meet the proper nutritional needs of the plant without forcing plant growth. The balanced formulation reduces the need for heavy nitrogen applications. It's like a multi-vitamin/mineral for your plants. Bio-Green can be mixed with Bio-Aer and Bio-Tree & Shrub to provide an unequalled plant health support program.
