Sulphate of Iron

I've been recommended to this as a good method of killing moss in the lawn and it seems to turn the moss black within 24-48 hours of application.

However, whether by machine spreader or hand, coverage seems to leave patches and I was wondering if anyone knows whether the granules can be dissolved in water and sprayed, as this would ensure an even application.

Secondly, what does one do with the black moss? Can it be left to rot away or does one need to rake it out?

Hi Blowin
You can mix with tepid water for even coverage.when it goes black it is a good idea to rake off.If you are left with large patches it is a good time to reseed.just brush some compost over the patches and seed on top

I always dilute it in boiling water then strain it into a sprayer, first go up the lawn then across that way you get good coverage, after a week it should turn black then rake it out ,it you can use a scarifier, remove all thatch and moss then if possible aerate then reseed or feed.

I usually get a 1 litre jug fill it with sulphate of Iron this i dissolve and add to 15 ltr sprayer, just keep spraying up and down and across until you use it up. It will not do any harm but dont spray it on paths or hard surfaces otherwise it will mark same.

Thanks for that info Greengage. I've heard loads of people suggest that form of applying it but none could tell me the mixture until you did.
