Works great

Been wanting to try something to get moss out of lawn and flower beds. This worked great. Turned it black and grass a darker green. I wanted to put all over lawn but ran out. Finally found more. You do need to put on a bit heavier than regular fertilizer but it works! With all the shady areas the moss just gets out of control and looks gross. I might try the spray for the brick walls and driveway next. Love this stuff but hope the price goes down soon.

We use this every spring- easy and reliable

We live in the PNW and get a lot of moss in our yard over fall and winter. We use this every spring. It is easy to use, and we usually follow up with dethatching, aerating, weed and feed, and this year we put down soil and grass seed. Highly recommend to kill moss in your lawn!

I've used this for years because it works. Heavy moss needs a little more. It was the cheaper price too.
