Sorry, No pictures, but I overseeded my lawn last fall and about 4 small areas came in very thick and light green. I thought after the first couple of fert treatments this year the roots would continue to develop. Today I raked those areas and the grass littlerally would pull easily out of the ground. The blades never stood upright, rather they seemed to have always lyed on the soil. I removed the grasss and will reseed. No signs of grub infestation.
