Q.My Pink Muhly Grass Is Brown
I planted my Muhly grass in early June, I live in zone 7b and it has gone completely brown. Should I worry that it is dead, or will it come back as temperatures cool a bit? It was regularly watered when planted but then I relied on rain to water it. It’s also planted next to pampas grass and another ornamental grass that are green and thriving.

It may not have been established yet when you quit watering. I think I see some green in the center. You may have caught it in time if it just needs more water. If it doesn't rain each week, I would give it a deep watering. Even though it is a drought tolerant plant, it needs to be established before it can go without moisture. (I lost a couple by not watering enough.)
The other consideration would be to check for good drainage. Muhly grass doesn't like wet feet. So it's possible it was overwatered in the beginning and root rot set in, especially if the site doesn't drain well.
