25KG Iron Sulphate

Just applied 3 days ago grass already turning a nice dark green colour and also turning the moss black,a very good product applied with a sprayer recommend this item.

Worked well, would recommend

It did the job i wanted it for to kill moss in the lawn

Every year I scarify the lawn and overseed to keep it well maitained. This stuff is excellent for killing g the moss and then running the scarafier over it to remove the dead moss from the garden.I still find it difficult to get the measurements right tho. Sometimes my grass is a dark healthy green colour and other times I turn it black. Great stuff, always delivered before delivery date. Recommended

Use plenty and it will kill the moss, till next year !!

Works beautifully. Moss dead and lawn lovely and green. And a 5kg tub is going to last me forever…(Typically you need 2-3g per m2 of lawn so even a large lawn doesn’t need much)

I use for killing moss , used straight , just sprinkle small amounts on effected areasKills the moss on damp moss covered pathway.Note Not used on lawn ,so cant comment

I've been using the liquid equivalent of this for a couple of years but it was becoming to expensive. This powdered version is actually better by far with the advantage that it keeps really well in it's container. I find the best way to use is to make up 25 grams in 5 litres of water using a little warm water to dissolve the crystals first. Cut the lawn but not too close, I cut mine to about 40mm. I then applied the mix using a small hand sprayer and sprayed this over approximately 60 square metres of lawn. After 24 hours all moss had blackened and the grass turned a deep green. If you use it this way you will find it goes much further than using it dry or in a watering can which can take ages if you have a large area of lawn. You may fins some areas of grass darken more than others initially but this is nothing to worry about and the dark areas will disappear after a few days or after the next cut.
