Rated 1.7 out of 5 by 6 reviewers.
Rated 1 out of 5 by Doesn't Work Product doesn't work. I live in Oregon, and even after multiple applications, there was absolutely NO noticeable moss death. If anything, as spring has begun, it looks like the moss is enjoying the wonderful orange smell and growing. I've waited two weeks to post, just to make sure it wasn't slowly killing the moss. It's not. March 11, 2014
Rated 1 out of 5 by Useless! No impact on moss. Other than smelling like oranges, this product had absolutely no impact on our yard or driveway moss. I used the whole quart in a 225 sq ft area and the result was no change, nothing at all! If you read this before buying it, skip it and count yourself lucky. The manufacturer doesn't even list it on their web site. October 31, 2012
Rated 1 out of 5 by USELESS This product is useless for killing moss. Even if you pour it on moss directly from the bottle undiluted, it will not kill moss. June 28, 2012
Rated 1 out of 5 by did not work as claim My algee and moss in my stone as well as grass still the same, don't buy this product. It did not work June 19, 2012
Rated 1 out of 5 by Sounded good, but zero performance. WOW! This product was absolutely ... WORTHLESS. Applied to green moss on brick walkway following instructions to the letter. 36-hours later had same green moss. July 22, 2012
