grass near cedar hedge
 

Hi,

I got a question about my grass problem near the ever green cedar hedges.
The problem is, there is no grass (anymore) ... just weeds. I know that
pine needles make soil acidic but I'm not sure about cedar hedges since it
doesn't have any needle and the "leaves" (I'm not sure whether it is called
leaves for cedar hedge) never fall off. I'm guessing it might be the root
of the cedar hedges making the lawn shallow so the grass can't grow deeper
into the lawn.

Any idea?

Thx,

Alex
