The landscapers planted a new tree (1 1/2 diameter) in the middle of the sod they also installed. They have the yard set to be watered 3x daily for half an hour at a time (the sprinkler heads are the low-flow Hunter rotator ones).
Is this too much water for the tree? If I tone back the water on the sod will that be too little water for the lawn? Do I need to give the tree a deep watering at some point?
One suggestion I have found is to remove the sod in a 6' ring around the tree -- but doesn't that ignore the fact that there is still water going to that area, and probably even more water to the tree since there's no sod to soak it up?
Edit: Some more information - Yard is in Colorado (very dry, has been in the 80s), with Colorado's typical clayey soil. The tree is a Box Elder.
