Hi,

Does anyone have any recommendations for efficiently killing moss in grass? It's obviously been a very wet few months and there seems to be scattered patches pretty much everywhere is our garden. There was none at all last summer.

Amazon seems to suggest Iron Sulphate like this is a good option? Would this be a sensible choice for about 250sq meters? It sounds like a 2kg tub for £12 would cover that kind of area - sounds cheap but great if it works?

Also, when should this be done? Is now a good time before it's been cut for the first time or wait till it gets warmer?

Thanks :)
 
Personal experience only, our lawn used to get moss pretty bad now it doesn't, so this works for me.

Firstly, and I've heard differing opinions about this, I don't cut it too short at the end of the year.

Second, use a lawn feed/moss killer, but the most important time to do this is anywhere from November to about now, you get specific "winter" lawn feed, it makes by far the most difference doing it during the dark months.

Occasionally I'll scarify but honestly last few years I've not even had to.

Iron sulphate does a great job on moss and you don't need much.

AFAIK the stuff in preparations you can buy that claim to kill moss is iron sulphate.

Yes I have done the same, it does work and bought without "fancy" packaging, it's much cheaper. Mine gets it badly but I'm loathed to spend too much on it because I only rent...but I also like being there in the summer so put a bit of effort in!
 
we use mo bactor - kills the moss and breaks it down to feed to lawn so your not left with dead black moss everywhere to take up, really recommend it.

Do you think it would work if the moss has completely taken over? I'm wondering how it could deal with serious areas of moss, I assume you'd need to reseed a lot of areas.
 
I used mo bactor at the back end of last year but still have a lawn full of moss sadly. Not sure if it’s worth giving it another go shortly or going extreme with iron sulphate and scarifying?
 
I would start off by hammering it with a scarifier. It will look a mess for a month but it will come back if you keep putting weed and feed on it.

If you want a nice lawn, use weed,feed and moss killer every 2 weeks but cut the lawn every week while your feeding it. Don't cut it to short tho.

Once it thickens up just use feed it once a month to keep it in check.

I wouldn't use the company's like green thumb or green sleeves. They don't use enough moss killer and it just make the grass to think. If you stop them coming the grass thins out and put pops the moss again that's hiding underneath.
