Greener and stronger when applied correctly!

This the the second year I've used over a new lawn this very good results. Grass is observably greener and healthier than neighboring lawns. The perfect jump start if used according to instructions. Too much, off course you'll burn it as is true with all fertilizers. Last year, I thought it caused a spark of clover....until I looked around and there was clover all over the neighborhood at the same time. Tis the season. Use a mask though, stuff is no fun to breathe.

Over many years I've tried to grow grass in my front yard to no avail. I have a large dogwood tree plus my neighbors trees also my soil is very compact. I saw this product and decided to try it. for the first time in over 20 years I have a great lawn beautiful thick green grass. I am thrilled with the results
