In order for plants to grow the fastest and biggest possible and in order to help plants survive diseases and pests, products such as Miracle Gro fertilizer have been created. Miracle Gro is made up of the same nutrients that plants have always needed, such as nitrogen, potassium and phosphorus.
Miracle Gro fertilizer contains nitrogen, phosphate and potassium. The amount of each of these nutrients is found on the bag of fertilizer under the fertilizer analysis label. The numbers are in order of nitrogen-phosphate-potassium and indicate the percentage of the material that is made up of each corresponding nutrient. Other micronutrients and filler material are also added to Miracle Grow fertilizer in order to ensure that the gardener does not add too much of a particular nutrient, according to North Carolina State University.
Miracle Gro has different mixes of fertilizer depending on the types of plants grown. All purpose Miracle Gro has more nitrogen and less potassium. Rose and flower Miracle Gro have much more phosphorus and have an even amount of nitrogen and potassium. Tree and shrub Miracle Grow has a large amount of nitrogen. Vegetables are given more nutrients than usual and have a very high amount of potassium.
Some forms of Miracle Gro come in a powder that is sprinkled over the soil and gradually seeps in whenever the soil gets wet. Other forms of Miracle Grow come as granules that are added to the watering can before watering.
Nitrogen is one of the most essential nutrients in life and is a part of all enzymes, proteins, metabolic processes and transfers of energy. Phosphorus is necessary for creating starches and sugars that the plant lives on. Potassium helps plants develop fruits and resist diseases, according to the North Carolina Department of Agriculture and Consumer Services. Both nitrogen and phosphorus are major components used in making the chlorophyll that plants need in order to engage in photosynthesis.
Miracle Gro potting mixes contain many of the nutrients needed by plants in the soil itself. This is helpful since nutrients sometimes take time to become integrated into the soil, so potting mix speeds up this process. Organic materials such as peat moss are often added not only to give the plant nutrients but also to make it easier for the soil to drain while still holding some moisture.
