please help new lawn weeds!

Hi there me again my new lawn is growing great, its about 4months now and looking good.
Problem is when i was mowing i noticed a weird weed i think intwined within the grass, too low for the mower to cut. Anyway when i looked closer this stuff was everywhere i got to buckets full.
I know i cant use weed killer yet as grass is too new if it is a weed?
I used john west seed so i just dont know how this got there?
The previous owner had this all as a large vegatable patch but was already cleaned before i moved in.
Any help pleeese!

 

Does it have a very small yellow flower on it - if so it could be 'lesser trefoil'?

 

No it hasnt

 

Parsley-piert maybe? Had a look through lawn books but difficult to tell!

 

I was hopinv this was a common problem but it would seem not!

 

Oops too many!

 

You probably can't put any selective weedkillers on the lawn until its 6 months old. If this is not a common lawn weed it won't be able to survive being in a lawn, so repeat mowing or treating with selective herbicide is going to be effective, so I wouldn't panic (until someone tells you that it is a normal, problem, lawn weed ...)

I alternate between two different selective lawn weedkiller brands (that have different "ingredients") as I find that that gives me a better kill with some weeds being missed by one, but not the other.

 

Thanks for your reply.
They seem like they are thriving ok at the moment!

 

Yeah, they are getting below-the-radar of the mower! Might be that when the lawn is more established you lower the blades a bit (although it looks like a creeping weed, so that may not help) ... or the selective weedkillers are going to kill them at the first attempt.

 

What you could try, though you'll end up with a bare patch, is to apply, by hand (gloved) directly to the centre of the beastie, a sprinkling of Sulphate of Ammonia, just a pinch really. This also works with persistant dandelions as well, manages to burn the centre and roots but you've got to get in close and don't apply on a windy day (or night).

 

Update
I called the supplier they had no interest in helping me as i dont have the receipts.
I cleared all the weed out but has now come back with avengance!!!

 

I took something back to B&Q once and because I didn't have a receipt they initially refused to give me a credit note. I pointed out that under the Data Protection Act they have to legally provide you with all information they hold on you, including receipts, so it was up to them to provide me with a receipt They are permitted to charge you for the information though (usually about £10).

I stood my ground and argued with them until a queue formed behind me - they usually don't want other customers to see them being unreasonable, so they caved in. I'm gobsmacked sometimes by how little customer services reps know about the DPA and the Sale of Goods Act. If your supplier refuses to budge then try writing to their head honcho in an envelope marked "Personal - Addressee Only". I've had many successful outcomes doing this because even if their PA opens it, you still get action at a higher level as they will pass it on to the relevant head of department.

The SoGA dictates that the product should be fit for purpose, which this turf obviously isn't.

Did the supplier sell you the turf or did they lay it as well? If the latter then you are covered under the Supply of Goods and Services Act.
