I’m in AZ as well, and while my grass and vegetation looks solid (considering), the summers here are brutal and there is borderline no amount of water you can put down to keep things lush when we have 100+ days of 100+ temps. I heard on the radio yesterday that the average temp this summer was 99 degrees. I have some bushes that just cannot handle the heat and are struggling big time, but they will come back. I have tops of citrus and Ficus trees that are physically burnt. No amount of water will keep that from happening.
But, all in all, my yard looks better than all my neighbors yards…
