2 years ago I skimmed off my old lawn and then took about 3 inches of soil away and replaced it with a good helping of top soil onto which I laid a new lawn. After the first year the grass looked fine(apart from a few dandelions) but this year there seems to be lots and lots of what I can only describe as 'wild grass' . it seems to grow in circular clumps and thay are dotted around all over the place. Does anybody know how to get rid of this stuff before it takes over the complete lawn, I can't individually gig it out because there is so much of the stuff.
Many thx in advance
