Let me start by saying we live in Northern Arizona. If you want nice green grass you have to plant it. You have to water at certain time of the day in order to keep your grass from burning up due to the Desert Heat.
We recently( last summer) put up a privacy fence in our back yard so our neighbors couldn't stare at our family in the jacuzzi we bought.
The line string on the pic is where we put fence line due to property line issues with the neighbors being upset about us putting in the fence. So we put the wooden fence more on our property and left their fence as is.
Any way this is what it looked like last year. Now, the grass line has receded Quite a bit! What we believe is happening is that our neighbors have been spraying weed killer.
We can't prove it!
Thinking about adjusting our surveillance cams to catch if they are.
