Patches of dead grass
I thought my lawn was healthy last autumn but this spring there are scattered areas (~6 to 10 inches) were the grass is brown and apparently dead. Last year I dug into some of these and found a few white grubs that I assumed were cutting the dead grass from the roots. I did nothing to control the grubs. Is it likely my lawn has the same problem again? and what should I do (and when) ?
Thank you for contacting Extension.
