25KG Iron Sulphate

Works well

Great for the lawn

Works well and kills off the moss within hours turning it black. It was a good price and my only complaint is that the container is quite flimsy and broke when I took the lid off

I apply this product and similar to my lawn about 3-4 times a year and all seem to have similar effects. Green up really quickly and helps feed the grass. I usually apply by watering can which takes forever but ensures that the product reaches the roots and does not just sit around on the surface

Grass looks greener and moss looks blacker, so the product does what it says on the tin. First started seeing results after about 2-3 days. With full effect about 7-10 days later. However, it simply cannot be sprayed. It clogged every sprayer I tried because of small bits of contamination, which block the nozzles. From reading other reviews, this doesn’t appear to be a one-off bad batch, but a fundamental issue with the product. It ruined two different 5L over-shoulder hand-pump sprayers, and I eventually had to throw it on the lawn by hand, which resulted in a slightly patchy finish. Bear this in mind if you’re planning to apply it with a sprayer as the manufacturer suggests. Top tip : Keep this well clear of your patio and stone work! otherwise it will cause rust spots. Think about wet feet/animals spreading it by mistake !

You can hear the lawn thoroughly enjoying and digesting the goodness from this product. Worth the money to cheer up any area of grass. Give it a treat!

Comes as instructed easy to use value for money

Was a bit skeptical at first. As far as I can tell, ALL the suppliers of this product (Iron Sulphate) on Amazon have just copied and pasted the same product description - even if it didn't apply. Made it very hard to choose which one to use. To this supplier I would say - don't be so lazy. Write you're own ACCURATE product description. It will make you stand out from the rest of the options, and help you sell more product (I know - I'm a marketer by profession). With that out of the way - applied according to the instructions. Product dissolved no problem into my 10 litre watering can. This seemed the easiest way to apply, and it was. Paced out the area I was treating (10m x 1m sections) and walked briskly as I poured. This gave the area the 5g/liter/square metre dose indicated to kill moss. Left overnight, and 95% of the moss has turned black. The rest I put down to having missed during application. I will reapply in two weeks after scarifying. But so far, so good.
