Iron sulfate
This is exactly as described, it arrived as promised, appears to be well made, and a good value for the money I just wish they would put a packing slip in the package. This came in the manufacturers packaging 👍 Limited or no single use plastic 👍 No polystyrene foam packing (styrofoam) 👍👍

Great
This stuff is great! Stopped my plant from chlorosis! Now I put it in the soil twice a year and the plant is thriving!

Does the job
The instructions warn about possible staining of concrete. IT IS TRUE! Can't hold it against them; that is the nature of the chemicals. If it is a concern, consider an alternative to iron sulfate.

Dissolves fast!
Iron content was great, but the re-closing bag didn't work.

It works!
Couldn’t find anything to kill moss. This does it. I mixed it with water and sprayed it on. Amount for spraying may vary.
