Review: Works As Intended - Used to kill moss in paddock. Didn't use immediately and found that the powder was compacted, so transferred to a bucket to crush lumps so it could be distributed using a spreader. Moss turned black within a day or so.
Review: Fit for purpose - Worked well to kill off thick moss, but dead material still needs removing. If you use too big a dosage your lawn will over blacken

## Questions & Answers

**Q: Is the grass harmful to small livestock (rabbits and guineapigs)  once the lawn has treated?**
A: Sorry. I don't know the answer to that question as I don't have any small livestock. However if garden birds are anything to go by there seems to be no ill effect at all. I regularly have Robins, Blackbirds, Wood Pigeons, etc. pecking about on the lawn. They were there weeks before I started using the Iron Sulphate treatment on the lawn, during the process (which, I must admit, did alarm me because I wasn't sure if the treatment would harm them in any way) but, I'm pleased to say, they are all still around today. For garden birds and even a squirrel that unfortunately regularly visits the garden to dig up parts of lawn looking for buried food, I can honestly say, there have been no ill effects at all. The wildlife, I'm pleased to say, is still going strong.

**Q: Can this be used to kill moss on soil and rocks etc**
A: Yes it certainly can. Moss turns black and dies in anything from 1 hour to 24 hours.  However, on hard surfaces it will stain a rusty colour and this would probably happen to the rocks also. Some would say the rusty orange staining adds character but its not to everyone's liking.

**Q: can I still compost the grass after this has been used on the lawn?**
A: I would not advise this as the iron sulphate would cause damage to plants if you used the compost, also don't compost the ist 4 cuttings as that will allow the bulk of the iron sulphate to be removed from the lawn

**Q: How many tea spoons or table spoons do you add to a10 litre watering can to kill the moss ?? Thank You**
A: I can’t remember I calculated it from the instructions... sorry not much help !!!

### ⭐⭐⭐⭐⭐ Works As Intended
*by C***Y on 18 March 2025*

Used to kill moss in paddock. Didn't use immediately and found that the powder was compacted, so transferred to a bucket to crush lumps so it could be distributed using a spreader. Moss turned black within a day or so.

### ⭐⭐⭐⭐ Fit for purpose
*by N***N on 21 January 2018*

Worked well to kill off thick moss, but dead material still needs removing. If you use too big a dosage your lawn will over blacken

### ⭐⭐⭐⭐⭐ Product does a great job in greening the grass and browning the moss this early in the season
*by M***N on 19 March 2017*

Ord from Home and family. ord 14/3/2017 arrived 18/3/2017. This was a re-order. This product is great at 'greening' the grass and 'browning' the moss at a time of year when it's too early to use other such products. One dose sprayed on in Feb and one in Mar. I'll spray again in April and then switch to Scotts Lawn products. Oh yes whilst the lawn is fully shaded and so the grass is patchy what there is looks fine, no yellowing etc. So whilst the lawn will never sadly win any prizes it's nice to see what there is all nice and green. Happy bunny. Well update used throughout 2017 and didn't feel the need to use anything else to make the lawn look enviably green and lush. I've just (26/1/2018) used again to get an early start on suppressing the moss which in this continuous wet weather is everywhere at 600g per 12 litre sprayer. Great stuff and I'll be getting so more. Well another update lets see ord from same supplier in 2016/2017/2018 and 2020 works a treat on killing the moss which in March 2020 was covering 50% of the lawn following the first qtr rain in 2020. Looks like overseeding is needed. Grrrrr
