An absolutely reliable product in terms of moss destruction. I mixed the iron fertilizer as directed in the watering can and poured my lawn. You could see how the moss blackened and enters. Other weeds in the lawn were dark to black and walked one. After that, I scarify my lawn and sown new lawn seed. The grass helps the iron fertilizer to get a nice green color. Until now it's my lawn very well. Of course, here and there are still a few weeds and clover in the lawn. This iron fertilizer I will apply to next year to get a more beautiful lawn in the fall again. The iron fertilizer is recommended from my side.
