Brown patches in the lawn

Hi All

This year, I am getting this brown patches all over the lawn. What could that be? I have been raking out brown grass or moss quite often maybe 2 - 3 times a week, but no changes. A lot of brown thatches were coming out whenever raking.

Following is the photos of the lawn this evening, and I have already raked out tons of brown thatches this afternoon.

Thanks for your advice and info.

 

Have you used any weed killer or feed on your lawn this year hedgefog?

 

Yes, I have given some liquid feed (diluting) about a month ago.

 

My first thoughts are dead moss but I'm not sure. Could you take a picture of the whole lawn or a good part of it please. On this occasion the close up is not enough, sorry.

 

No probs Sheal - here is the photo from upstairs looking down into the lawn. It looks not too bad from distance, but when in the lawn and looking into the grass closely, it looks problematic.

If they are dead moss, then I am wondering why so much and often they are appearing overwhelming the grass. Thank you for your info and advice.

 

It's amazing how quickly moss can form in a lawn, a damp winter is all that's needed and particularly if it's combined with the way the garden faces. North and east being the worst as it never really gets a chance to dry out.

I'm a little stumped as to what's going on here. Thinking out loud. The first pictures tell me three things.....

1. That it's dead moss and there's an awful lot of scarifying to do.
2. That your lawnmower blade is blunt and it's tearing at the grass.
3. That your lawn needs aerating and feeding again.

Your last picture tells me it looks healthy enough but still has thatching there.

I think the best thing would be to leave it now for the summer, it's never a good time to work on lawns and then start again early autumn. Aerate the lawn and then use a weed and moss killer. Scarify and then give it an autumn feed, this is different to a spring/summer feed as it contains different chemicals.

 

Thank you for informative and helpful advice. Will follow your instruction, and will wait and see. cheers
