Advice needed - new sod lawn dying in random patches
 

Hi,

We installed a new fescue sod lawn nine days ago. All was going well until
just a couple of days ago, when randomly sized and spaced patches began
turning yellowish-brown. These dying areas have no roots whatsoever - the
bottom of the grass "stalk" is completely blunt, suggesting that something
may be eating the roots. However, with the exception of exactly one white
grub, I have been unable to find any other sign of grubs or bugs anywhere
in the lawn. The unaffected areas are taking root and coming along
beautifully.

I am in the process of finding someone local to properly diagnose this
problem, but I was wondering if anyone might have any suggestions in the
mean time.

Thanks,
-Bob
