If your lawn is in such sad shape that either your neighbors complained (it happens far more often than you think) or the HOA Mgr. came by, I would suggest that you read the yard care info in the monthly bill if you live in the gated community.  You can water early in the morning, late at night, and you can make sure that you or your gardener (I doubt you have a gardener…) do not cut the lawn too short as it will burn. Be sure to check for broken sprinkler heads as they waste water that could go to the lawn.   Also, be certain that if and when you fertilize you give the lawn sufficient water so the lawn will not burn.  Do not complain that the community would like you to have a nice looking home.  And, if you have polite questions, call the number and ask to have someone come out and have a talk with you.  As important as it is to have a nice front yard, the back yard also says alot about our community, and often to guests.  We should all look our best.  It is NOT hard to keep a nice lawn. Look around you.  Does your home stand out?  Good luck and I hope that you take some of my suggestions to heart.
