What is this stuff?

Hi, First post....Thought I'd see if anyone can help.....

last year i got seriously angry with our back lawn... it's been a mess for years, really since the house as built...made a BIG mistake about five years ago when I had it rotivated and then seeded it almost a week later..

ANYWAY, I got sick of the dandelions and thistles some, literally as big as a dinner plate.. so I sprayed one of those "kill weeds and roots" thingys on them, gradually killing the weeds, but also large areas of the grass...

OK, by feb, about 90% of everything was dead, so I killed the rest off....

raked out all the dead stuff, then in mid April (warm enough down here) I sowed the whole thing with new seed....

All was well for a few weeks, then I noticed large clumps of something that wasn't grass...something quite thick and bushy, that sends out "creepers" and expands to form large areas quite quickly... bushy, but as I dig them up, the plant has got a single thin taproot type structure...

Is it camomile.... ?

I'm P****d off!!

I don't want it, I WANT GRASS!!

Any tips as to how to get rid?

(short of digging huge areas up and starting again??

I can't beleieve it is camomile with how p****d you sound

OK, three more pics... one in the ground, the other two dug up... measures approx 3cm across at this stage, but will grow into the monsters above... it has a somewhat musty, pungent smell

Any ideas?

No idea what it is.

But if you think it's a weed (It probably is) you can compare it to these weeds, here, & try and work out which one is destroying your lawn.

 

The closest that I can see is pineappleweed... but it doesn't smell of pineapples!!

 

I can say its not Pineapple weed, it's also not on that ID site.

I keep think Rue when I look at it but i'm away from my books at the moment.

This might have been a bad move Merseygull, as we're going to ask you to let it flower now so we can properly ID it:D:DOH:

 

Whenever I find something wrong with my lawn (There was some moss in March) I always just end up cutting it out and then throw compost/seeds onto it.. but if it keeps coming back, I have no idea what I'd do, to be fair.

 

I'm wondering if it's Stinking Chamomile, Anthemis arvensis. It's often found around stony field margins and despite it's name, it smells similar to cultivated Chamomile.

Does it actually matter as to what the weed is?

"Weed and feed" might sort it out.

 

My only worry with that is that the grass is only a few weeks old (although it's grown so well that I've been able to cut it twice)

I'll keep a beady eye out for the first sign of flowers....

Weed and Feed, but water it in well.

It does what it says on the packet, it feeds the grass and kills broadleaved weeds.:D

 

OK, will do..., but will I have to treat every year?

Hopefully not, but its a good idea to apply lawn fertiliser every spring if you can.
Most do contain a weed/moss killer.
