Pro-Kleen 2.5 KG PREMIUM Iron Sulphate (Makes up to 2500L When Diluted & Covers up to 2500m2) - Iron Lawn Conditioner and Turf Hardener. Dry Powder soluble in water

Use diluted or dry Iron sulphate will kill off lawn moss cheaply and easily

I used 3 miracle grow scoops to 10 litres of water in a watering can. Watered lawn and it was full of moss 24 hours and it was black and dead . This bucket will last forever .

Good

I found it ineffective at the rate suggested it should be used shown on the container purchased over a year ago. On my recent purchase their recommended use was increased, but my experience so far still shows to be not effective even at the newly recommended rate.

Seems to have worked well for me, after moving into a property with more moss than actual grass as a lawn turned moss black ready to scarify and remove. Also added a small does into my lawn care regime to help keep a nice dark green

Did the job as required

This product is very effective in controlling moss and value for money.

I've used this product two years in a row since laying a new lawn. We have a very shady north facing garden - prone to moss - and this stuff does exactly as described, plus it keeps your lawn looking green and healthy during the low light months without causing grass growth. Use a couple of table spoons (approximately) per 6ltr watering can and pour evenly over entire lawn. If you don't notice the moss turning black after a week. Apply a small amount more to where the moss persists. Watch out for decking or sleepers, as it can stain....... Found that out the hard way..... Ideally I think this is supposed to be used as a preventative treatment, rather than a corrective, so apply in mid autumn to reduce the moss taking hold in the first place, however it does equally well at ridding it once it has appeared.
