Grow a lush, green lawn!

16-4-8 Lawn Food contains the three essential macronutrients, Nitrogen, Phosphorus, and Potassium fertilizer. This liquid lawn fertilizer contains Nitrogen, Phosphorus, and Potassium. This all-in-one NPK fertilizer is designed to encourage turf greening and grass growth while providing nutrients for strong roots. This Nitrogen, Phosphorus, and Potash grass fertilizer is infused with Seaweed (Kelp) and Fish for optimized nutrient efficiency. 

16-4-8 is a great option for spring and fall fertilizer if you have a cool-season lawn. For warm-season grasses, apply as a spring or summer fertilizer, with a micro nutrient fertilizer to maintain color. 

Nitrogen 16% 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 fertilizer can provide ideal conditions for a dense, attractive lawn.

Phosphorus 4% The proper level of phosphorus in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus fertilizer effects on turf are usually more subtle and, while not as readily visible, are still very important.

Potassium 8% is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium fertilizer plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient. A plant deficient in Potassium can be more susceptible to stress from drought and temperature.

Seaweed & Fish Emulsion Fertilizer: Kelp (Ascophyllum nodosum) and fish, organic matter for a more effective Lawn Food and optimum nutrient uptake.

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.
