Just pulled it out by hand at the root, but I suspect it will re appear. Photo next time.
Found it - Selfheal!
The other one I have in a few patches is a long almost feathery weed, Ill get some pics. I think its yarrow looking online, guess I need to do some more general weedkilling rather that spot killing. Dandylions and daisys and buttercups all but banished I think.

The house I have just bought has a large lawn and alot of this in it. Found it - Selfheal!

Anyone know how long after overseeding till you're ok to use Weedol?
Manufacturer guidelines suggest at least 2 months after establishment for new lawns, so I would treat overseeded areas the same.8-P said:

Yes thats selfheal and most likley yarrow too (looks like a small fern or xmas tree) both are resistant to your normal broad leaf weedkillers. professional products like holsterXL will rid of both, whilst you wont (or shouldnt) be able to buy this, you can double check the active ingredients against off the shelf weedkillersFound it - Selfheal!

To be honest I've never really noticed much effect from ferrous sulphate. Likewise, I don't have any problems with moss, but I don't really see much of a green-up. Perhaps my lawn is not iron-deficient.
Recently I've been hand-sprinkling quite generous amounts of it over the worst areas of Poa annua because I've read in several places that the acidification might disadvantage it compared to the 'proper' grass. Then I water it in to prevent blackening of the grass. There has definitely been an acceleration of the die-back of the Poa, but that could simply be because it's the time of year when it should be dying back anyway.
Yesterday I took a stout metal rake and attacked one of those areas to remove some of the dead material, then scattered a generous helping of seed and a bit of compost. Will have to keep it well watered in this coming hot spell, but since I'm studying at home at the moment that shouldn't be a problem. I'm hoping to get some germination and establishment of new grass over the next few weeks, then in early September I'll apply another dose of pre-emergent herbicide (Scotts crabgrass preventer, bought from the American Amazon - no idea why it's not directly available in the UK). That will hopefully limit the germination of Poa annua in the autumn and reduce the amount of it next year. I've decided against scarifying or any further overseeding for this year.

Iron is an important element for turf, used by the grass plants for nitrogen metabolism and chlorophyll production. In higher pH soils there can be inadequate levels of iron available; in extreme cases this can lead to iron chlorosis and yellowing of the grass leaf.
Even with adequate levels of iron available in the soil, additional iron sulphate can result in a deeper greening of the turf which is preferable to achieving the same through excess nitrogen application with the resultant lushy top growth and susceptibility to disease.
Iron is normally applied in autumn to strengthen the turf before winter, when the short days and lack of strong sunlight are an impairment to photosynthesis. That said, it can be used throughout the year to help acidify higher pH soil and as a way to green up the lawn so that it's looking its best before hosting garden parties etc.
As always, care in application is important as excessive amounts will kill the grass just as easily as excess fertiliser input etc can.

Would one of the grass gurus mind giving some comment on this. We had some very large trees removed from the corner of the garden which had pushed down an old fence and threatened the neighbours garage. Stumps ground down and we had ready turf laid. It had been down for 10-12 weeks and was religiously watered twice a day. As you can see despite watering it's gone very brown. What can I do to bring it back to good health. Thanks
Edited to add that initially it took very well but it has since packed a bit of a sad. Maybe i cut it too short. You can see the odd spot where i patched up a mower gouge

To me it looks like you've cut it way too short.
Looks too short for any time of year, but especially at the height of summer when we've been having a dry spell. Add to that the fact that your turf is recently laid.
Does your mower have variable height? If so you need to raise it up substantially.
Keep watering it every few days, giving it a thorough soaking not just a light sprinkling.
Perhaps feed it, using half the dosage recommended.
But most importantly, stop mowing the life out of it!
