Miracle Gro is a well - cognize commercial fertilizer mixture used for various type of plants , mainly flower and vegetable . Miracle Gro contains both macronutrients and micronutrients . Macronutrients are the ingredient that plants use in capital quantities and include nitrogen , phosphorous , K , sulfur , atomic number 20 and Mg . micronutrient are the essential elements that are used in pocket-size quantities but are still important to imbed developing .

Urea Phosphate

Urea orthophosphate is a pellucid substance made by reacting urea with orthophosphoric battery-acid . Urea phosphate is the principal N - providing compound in Miracle Gro , but it also provides phosphorous . Urea orthophosphate in itself contains some 17 percent nitrogen and 43 to 44 per centum phosphoric oxide . Nitrogen is a key nutrient in proper plant development , particularly for stem and leaf maturation . Phosphorous affects nearly all aspects of flora growth and is necessary for photosynthesis and heyday developing .

Potassium Chloride

Considered a macronutrient , potassium helps in body of water absorption and loss , prison cell division , and the processing of carbohydrate , starches , and protein in plants . Potassium also increases peak coloring material , works strength and dusty hardiness .

Sodium Molybdate

Sodium is essential in the drift of water supply in plant cells and ionic symmetricalness . Molybdate ( molybdenum ) acts to reduce nitrates to ammonia and enables plants to synthesize proteins , forestall nitrogen deficiencies .

Ammonium Phosphate

Ammonium inorganic phosphate ( monobasic ) is another chemical compound contained in Miracle Gro that provides the macronutrients N and phosphorous . Unlike urea phosphate , ammonium phosphate is more constitutional in supply phosphoric than nitrogen . Usually in a satisfying form , this chemical compound contains 11 percentage nitrogen and 48 to 55 percent phosphorous oxide . ammonium ion orthophosphate also contains tracing elements , or micronutrient , including 2 pct Ca oxide , 0.5 percent magnesium oxide and 1 to 3 percent sulfur .

Zinc Sulfate

Zinc is important in synthesizing protein and metabolizing carbohydrates as well as aiding in the part of plant growth hormones .

Copper Sulfate and Chlorine

copper color is essential to plant ' power to metabolise nitrogen . Chlorine is a key component in photosynthesis and mineral - component engrossment .

Boric Acid

Boric acid ( atomic number 5 ) is authoritative to many unlike plant functions , including seed development , cell division , inflorescence and pollen sprouting . Specifically , plants habituate boric acid in forming cubicle walls and membrane within the cell , as well as in absorbing calcium .

Manganese EDTA, Disodium Salt

Manganese is essential to plant life ' enzyme activities for external respiration , nitrogen metabolism and photosynthesis .

Ferric Sodium EDTA

ferrous sodium provides atomic number 26 to plants , which helps plants to synthesise chlorophyl and enzymes to go , peculiarly in young and actively growing works tissues . Soluble atomic number 26 like ferric sodium also prevents toxic carbolic acid compound , which cause plant root word to go , from forming .
