Lawn woes

Hi All

Newbie here.

I moved in to a new build house last year and planted the lawn out in September. Now in May after a couple of cuts and a feed of 4 in 1 fertiliser - can’t remember the brand it has started growing with very coarse thick grass weeds - excuse my complete lack of knowledge. I have attached a photo of them - my question is what are these weeds and what is the best way to get rid of them - there are hundreds of them as it is a large garden so digging is not an option. Thanks for any advice.

 

Hi and welcome i think its this.

Do you have a picture of the seed head by any chance?
When you say planted did you by any chance seed it and what soil did you use?

 

Hi Liz - I’ve attached a pic - not very good as it’s been recently cut. As for the soil I don’t know the type - I bought it from a farm where they were digging out to build a digester. There were 60 tractor trailer loads so it was quite a lot.

 

Shames it’s not opened but if you notice little hairs on the stems or it feels hairy the chances are it’s Yorkshire Fog. It’s also prone to looking less green than the other grass types even after a feed with iron.
Unfortunately it was from the soil you imported from the farm and to be honest if it’s everywhere the only way to treat this is via a weed killer or you spend hours digging it up removing every trace of the roots which may not be a viable option.
Some grass don’t like to be split, ie they weaken when sliced but it an on going process and not always effective.

 

Thanks Liz - what is the best type of weed killer - is it one that will kill all the grass or is there a selective option which I would much prefer?

 

There’s no selective weed killer for grasses, glyphosate is really the only choice ie. roundup.
You can either spray it using a hood attachment which will help to avoid drift or you use a weed wipe which is like a paint brush and you simply roll it on the grass.
If it’s really infested and you wanted to rid it completely then I’m afraid it would be a total kill and then a restart from fresh but if it’s just areas then you spray, wait at least 3 weeks and rake, dress and seed the patches again.
I should ask that the seed used is from a reputable source as well.

 

Thanks - I'll look into trying out a patch first and see how it goes.
