There are all of these… things… in my yard. Help!

I’ve been working 12 hour days and I get home after dark so I hadn’t noticed my yard lately. I came home in the middle of the day this week and saw my front yard for the first time in weeks.

It’s pink.

My front yard in Arizona was dirt and my back yard was rock.

Now, I have this:

The Backyard

The front yard

What do I kill first? What’s supposed to be there? What am I supposed to mow? Anybody got a lawnmower I can borrow? And will you show me how to use it?
