    Nitrogen 0.75% Nitrogen is the mineral element used in the greatest quantity by turf. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. The addition of Nitrogen encourages vigorous growth for the development of a dense attractive lawn.

    Iron 6% helps the plant move oxygen throughout the roots and other parts of the plant. Iron is essential to the plant’s production of chlorophyll.  

    Manganese 0.80% is an essential micronutrient that aids in the process of respiration and absorbing Nitrogen.

      Please note that if your lawn or plant's current iron levels are sufficient, adding an iron supplement will likely result in little to no visual response. This product is best to use when there is an iron deficiency or suspected iron deficiency or when iron levels are below sufficient.

      Water is essential for maintaining your lawn, and your lawn should receive 1-2 inches of water per week. Fertilizer will not treat a lawn that is suffering from disease, pests, weed infestations, or drought, and these conditions should be treated separately.

      Cool Season Grass. The lawn was previously not loved. Just moved in a few months ago and trying to turn the lawn around into something beautiful. Simple Lawn Solutions has been a part of that process.

      The lawn was mostly weeds. We took a soil test, killed the weeds, spike aerated, fixed the soil, and seeded. The lawn was good but SLS put it over the top.
