### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Mistral Ferrous sulphate
  

*by B***D on Reviewed in the United Kingdom 🇬🇧 on 26 March 2014*

Product arrived on time and of very high quality being dry, free flowing and lump free. The only negative was that the original packaging had been damaged and had been taped up and a small amount of the product was "leaking" out. This was not a problem for me but the delivery man was not too pleased. In general a very good performance.

### ⭐⭐⭐ 3.0 out of 5 stars

*by M***I on Reviewed in the United Kingdom 🇬🇧 on 13 June 2013*

The product was delivered on time and sealed, but on opening it was found to be in a damp condition.Part has been used and appears to be killing the moss.  However I am concerned that the remainder may deteriorate and be difficult to use.

    Iron Sulphate.
  

*by S***N on Reviewed in the United Kingdom 🇬🇧 on 1 October 2013*

Bought this to kill the moss in a large lawn. I applied it in two ways, the first was to dissolve the crystals in water at a rate of 10g/litre and applied with a watering can. This worked splendidly, the moss was killed uniformly within 20 minutes, and the grass which was not damaged in any way, greened up noticeably within a couple of days...perfect. As the lawn was so large, the watering can method was very time consuming and so I applied the Iron Sulphate by hand to the rest of the lawn, this is tricky to do. It resulted in patchy areas, some treated, some not and some so heavily treated that it temporarily turned the grass black. However, it didn't rain for a couple of days after I applied it and if it had, that would have helped wash the powder off the grass and into the moss. Iron Sulphate is a wonder treatment for moss, it will literally kill the moss while you watch, you'll see colour change in the moss virtually instantly. Forget expensive and difficult to apply weed and feed/lawn sand and get some of this powder, applied in a watering can it'll transform your lawn in a cost effective way. It kills moss, greens the lawn and toughens up the grass. Highly recommended.
