Hope someone can advise me on the causes and treatment for these clumps in my lawn.
The lawn was seeded when I bought the house and there were clumps in the lawn. They lawn was poor so when I was getting some work done I got them to lay turf as well and the turf started to grow clumps as well
What are they caused by and what can I do to treat the problem?

Even when the grass is trimmed these patchs are a darker green than the rest of the lawn.

those patches in the lawn show that the grass in these areas has access to a free draining rich soil whereas the rest of the lawn is poor compacted and low in organic matter and no free Nitrogen. As a test add a diluted liquid fertiliser eg tomato food in the form of an X in the lawn and after three weeks if the fertiliser has worked and the X looks good and rich then your lawn needs a dressing. A dog using the lawn as a toilet can also produce similar symptoms but not as pronounced.

Thanks Michael - when you say needs a dressing do you mean I should spray the entire lawn with tomato food or spread a standard lawn feed?

That's interesting to read because my lawn is exactly the same way. So thanks Michael. I'll be trying that too.

test a small area first with tomato feed in the shape of an X so that there can be no confusion as to where you treated, then give a dressing of lawn fertiliser to the whole area if the X turns a dark green colour.

Thanks Michael - seems to have done the trick - the entire lawn is now starting to green up nicely

that was a rather rapid result of the treatment. Judge it over a longer period for a more certain result.
