Have you fertilized it? Added lime to neutralize acidity. Acid soil

i've got moss growing in the middle of
crushed limestone in some areas around here.


I did use the word "prefers"

yep. still much better to actually deal with the
problems than to try to paper over it by spreading stuff.
we don't know if the grass is dying off from the tree or
what. no amount of lime is going to correct that situation.

the OP's post reflects common construction practices and
we're not sure if that is what's going on (sod over very
poor subsoil and perhaps a drainage/leveling problem). it
could also be a sign of other issues (light, traffic,
compaction, water flow removing organic materials, removing
clippings, ...). so many unknowns...
