Please can anyone give lawn-help?
I am totally at a loss about the way my new 6 x 6 metre lawn planted 1-4-17 is growing. It is blotchy
This was a wild area. I spent 4 months from January digging, de-stoning and flattening. I researched carefully and bought a verified lawn seed mix
I fertilised the whole are uniformly. I shook the bag of seeds well before planting, But from the start some areas sprouted quickly - a month before others. Now my lawn has nearly total grass coverage (95%) but is every week or so developing bright green patches where the grass grows taller, and which have a patch in the middle that goes brown and then dies. These "burnt looking" areas heal. But then new ones arrive somewhere else.
When I was preparing the area I dug it all deeply 3 or 4 times.
I have a male 11 months puppy who has been "done", and a neighbour's girl dog who has not been done, and I know sneaks through the fence. But it has been raining a lot recently...?
Please help. I have spent huge amounts of time and effort on this lawn, including removing boulders.
Thank you in advance
