Full Answer

Urea phosphate is a white crystalline substance made by reacting orthophosphoric acid with urea. Urea phosphate is the key nitrogen-providing ingredient in Miracle Gro. Nitrogen is needed for proper plant development. Potassium chloride is a colorless crystalline compound. It helps in cell division, water loss, absorption, and processing of plant proteins, starches and sugars.

Ammonium phosphate is a white crystalline solid. It is an integral source of phosphorus in Miracle Gro. Phosphorus is needed for nearly all aspects of plant growth, and is particularly required during photosynthesis and flowering processes. Ammonium sulphate also contains other minerals such as nitrogen, sulfur, calcium oxide and magnesium oxide.

Boron or boric acid is need for proper seed development, germination, flowering and pollination. Plants also use boron during the formation of cell walls and cell membranes. Miracle Gro also contains other essential nutrients such as zinc sulphate, copper sulphate and chlorine, all which are necessary to many plant functions.
