About Foliar Sprays
Foliar sprays are used to support plant health by feeding them directly through their leaves. Plants can absorb nutrients thorough their stomata, the small openings that let plants emit oxygen and uptake carbon dioxide, and epidermis, the small layer of cells on the outside of the plant. This uptake is much quicker than watering through soil, and can serve as an additional way to feed plants and correct for deficiencies. HTG Supply carries several foliar sprays from top brands, so shop today and spray away to your heart's content.
