How to Use Humic Acid

Humic acid is classified as a plant bio-stimulant: A material that promotes plant growth, health and development by inducing hormone activity. Bio-stimulants also help plants fight free radicals by protecting the plant from lipid (fat), protein and DNA damage inside of the plant's cells. Applying humic acid in the correct concentration for the correct application can benefit flower and vegetable gardens, soil, lawns and other growing applications.
