Hello,
Our garden and house is about 3 years old nearly and we have mostly had
a good lawn. But at the moment the grass is dying at the end and also
along one edge and around the base of a tree where there is a slight
dip. It appears quite wet so I wonder if the problem is poor drainage.
The lawn is about 5m x 15m. Can anyone offer advise to improve the
grass. Most of our plants appear fine its just the grass that has an
issue. There is also moss in some areas which I would think would
suggest a constantly wet area.
Many Thanks

this is very complicated to analyze without seeing it.

Could be lots of things, including disease or insects. Some pics of
the areas, plus some close ups of the grass blades would be a start,
though that's just one step.
