For the front, I mow it, edge and trim it, put out weed-n-feed twice a year, and that it is.
I don't water it. I have a big blotch that is dead and slowly growing back from last year.
The back yard I just mow, and it looks better than the front (but does not get as much direct hot sun as the front).
I can appreciate a well cared for yard, but I do not want to put the time and effort into it. My neighbor on one side has a beautiful yard, flower beds, trees trimmed and mulch around them and such, she won yard of the month in our subdivision last year. Makes my yard look even worse, until you look at the neighbor on the other side, his is the same as mine.
She also has he yard taken care of by her brother, who is a landscaper by profession.
