I had Premiere Turf out here to install artificial grass and its amazing.  No watering and no weeding at all.  It looks as good as real grass without the headache and upkeep.

Watering correctly the first few weeks is very important because it grows and strengthens the roots.  If the roots aren't deep enough, the grass may start to brown once you start watering on the every 2-3 day cycle.  Also don't forget to fertilize every 4-6 weeks.  It really does make a difference.
