Who Should Use This Product? 15-0-15 Lawn Food is best to be used...

  • To enhance your soil‚Äôs mineral content
  • If you want to enhance the green of your lawn
  • If you are trying to boost vertical and Lateral Growth
  • If your lawn is deficient in Nitrogen or Potassium

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.

  • Nitrogen encourages greening & vertical/lateral growth for a thicker, greener lawn
  • Potassium for plant hardiness & support of essential plant functions
  • Promotes the transfer of locked Up nutrients
  • Corrects Nitrogen & Potassium deficiencies
  • Covers 12,800 square feet
  • Can be used on all grass types
  • Proudly made in the USA

For best results, water the lawn for 20 minutes within 24 hours of application. 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.

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.
