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.
