New moss growing after overseeding

I did an autumn feed and moss killer in August. Power raked first week in Sept which left the lawn essentially scarified - a lot of bare areas. I overseeded and top dressed in second week of Sept and added a "pre-seed" fertiliser about two weeks later.

The new seed took pretty well but I still have lots of bare patches where it didn't grow for some reason. These are now filling up with a new growth of healthy looking moss!

I am thinking why let it get established? Iron Sulphate it now and then rake out in the spring when I am going to have to seed those patches anywhere.

Thoughts?

 

I'm no grass expert but won't the iron sulphate adversely affect the new grass shoots?

 

Hi Snorky85, thanks for the answer. I am thinking that the new grass is quite established now, and iron is good for grass (although possibly not in the dormant season, I don't know).

 

Hi Tim

there’s no harm in an iron treatment or a Autumn feed with iron as long as frosts are no due.
The iron will deter the moss and tackle the moss Thats there but I would not go raking like a mad man till next spring to remove it.

 

Thanks much. I'll have a look at the forecast and get on it.
