Hello All, I'm a homeowner and I've been on these boards a few other times with some different questions and everyone has always been a big help. Here goes... My sod was installed (new construction) in November 2008 just before the major frosts started. It turned out to be perfect timing. The following spring (and the majority of summer) we had almost a perfect amount of moisture - I still had to water a lot myself which I didn't mind - it was a new lawn that I knew would require a lot of work. Got through the year just fine until this year... ...certain spots (maybe 5-6 small "zones") will literally die within 2 days of having no water while the rest of my lawn will be in good shape. I wanted to find out what was causing this (my thought was that there was rocks/construction trash/concrete underneath the sod because when my wife and I were getting ready to till/seed our back yard we had to remove a small truck load of rock/trash/concrete) so I bought a hand aerating tool and sure enough in those areas there is a lot of rock and concrete because you can feel the rock/hit concrete in those areas. So, I have been manically trying to keep these areas alive with watering. My wife is sick of hearing me complain about it because frankly I am sick of watering these areas all the time. It's really becoming an issue from my point of view. Now, I have thought about getting an irrigation system (because I have almost 16000 sf total of lawn, the sod is probably just over 5000 sf) but that is obviously an expense that doesn't truly *fix* my spot problem (but all in all it would probably be an all-around good investment while saving those spots from their over-sensitivity). But, I have also thought that if I don't want/can't get an irrigation system that going back to the builder and blaming them is an option. Is this an option for me? Or is it going to go nowhere? Is a builder likely to tell me I'm screwed and that this is a problem of mine and not his? If I choose to go back to the builder what is the best approach to this?
