What Customers Are Saying
The product effectively killed moss, allowing the grass to regrow, though it may require multiple applications for larger infestations. It works best when applied as directed on a damp lawn, with visible results within a week. While most customers were satisfied with the affordable and easy-to-use solution, a small number found it less effective for long-term moss control.

Disappointed
Applied double the recommended amount and it barely discolored some of the moss. Last time I used it, probably a lesser amount, and it turned it all black. Maybe I got a bad batch or they are cutting back on the active ingredient that kills the moss. Kinda bummed..... :~(

You better put it on heavy!
Would Not RecommendVery disappointed! Hardly touched the moss, and I was putting it on heavy to where it did not cover 10,000 square feet.

Works great!
Applied according to the instructions and turned the moss black where I applied enough and other areas turned yellow and need more attention. Is this safe around shrubs and plants?

Killed Moss Fast

Not effective for large patches of moss
Would Not RecommendIt kills only the Moss that comes in direct contact with the powder / granules. The moss next to the ones in direct contact are not affected and continue to grow. You will have a green patch of moss with one tiny dead spot where the powder / granule landed.
