Pictures?
Like do you have a beautiful meadow full of wildflowers?
Or patchy turf that you've kept mowed?
Was me, I'd turn off the irrigation, and... Instant xeriscape!
Live with the weed patch, observe what lives, and, whether any of the plants grow on you.
Most people are not going to have magazine quality xeriscape, but... Learning how the "weeds" tolerate the dry conditions and learning to identify what you already have can be enlightening... And a cheap start on the eventual xeriscape.
