Start your lawn season off right!

Growth Booster contains the essential macronutrients to help get your new lawn established into a thicker, fuller, envy-worthy lawn! Growth Booster is great for seeding and establishing brand new sod, as its star ingredient is Phosphorus, which is essential for strong plants & roots.

Growth Booster is a specifically designed phosphate concentrate energized with Humic Acid. Our decades of research have resulted in formulas that are expertly manufactured with our proprietary manufacturing method, unlike any other product on the market. Our Humic Acid is derived from what is considered to be the highest quality humate source available, Leonardite. Our humic acid is obtained via a Proprietary Extraction Method versus made from soluble powder making it a very pure and active form. 

Who Should Use This Product? Growth Booster is best to be used...

  • When Establishing your lawn with Sod or Seed.

Nitrogen 6% 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 can provide ideal conditions for a dense, attractive lawn.

Phosphorus 18% 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 effects on turf are usually more subtle and, while not as readily visible, are still very important.

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.

This fertilizer contains Phosphorus and may not be used for lawn maintenance on turf in Maryland, Michigan, New Jersey, New York, and Virginia except when 1) Providing nutrients to specific soils and target vegetation as determined to be necessary in accordance with a soil test that was conducted by a laboratory* performed no more than 3 years before the application. 2) Establishing vegetation for the first time, such as after land disturbance, provided the application is conducted in accordance with the recommended application rates established by the state. 3) Re-establishing or repairing the turf area. *In Maryland, the soil testing laboratory must be identified under Section 8-803.7 of the Agriculture Article, Annotated Code of Maryland.

    Testimonials

    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.
