Thank you for the information. The symptom is very similar to dollar
spot. Is there any way to confirm it by a test ? Iam going to call the
county extension today to find out about turf/soil testing. Also I
like to find some organic way of treatment. One good sign is I saw new
grass emerging at one larger about 6" dia. dead spot.
TIA
Sam.

Hello,
My entire lawn has small 2" circles of yellow patches. This is very
visible in that last 2 days as its raining here in Northeast, zone 5
and the surrounding grasses are becoming more greener.
