Nitrogen 15% 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 can provide the ideal conditions for a dense attractive lawn.

Potassium 15% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. Potassium, the plant may be more susceptible to stress from temperature or drought.

The journey to my beautiful lawn was not an easy one. At first, I had no idea what I was doing and I was getting mediocre results. I found websites like Simple Lawn Solutions to help me on my journey and you can see the results in the photo. Hope you enjoy.

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.

Joseph B.

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.
