In just 3 weeks time it is 75% flopped over with only a few green shoots remaining. Stems are not brittle. Soil is slightly "clayish" but I don't see any "pooling" of water.Help!
If it's been especially hot in your area this summer, your grass may have lapsed into dormancy and should come back when it starts to rain again. Here's an article on how to care for it: https://www.gardeningknowhow.com/ornamental/foliage/muhly-grass/growing-muhly-grass.htm
I have 35 feet space that I am going to plant Muhlenbergia Rigens. How far apart should I space these if I want them to fill in the space?
the correct spacing for these will be 2-3 feet.
This article from the University of California will help you to care for the grass:

I live in zone 7a and grasses are planted in mostly sun and receive water from our irrigation system.
Once mature, they only need supplemental water during drought periods and should be planted away from irrigation systems. I'm wondering if too much water is affecting the roots. Here are the growing conditions for pink muhly grass.

I have ordered n already received my grass. Just hoping I can safely plant it now
It's best to wait till after the last frost and that won't be till sometime in April or early May, depending on where you live. (To get your date estimate, contact your local cooperative extension group.)
If you plant now and your area experiences a hard frost, you could lose the plant, which hasn't had time to settle in its roots.

What is the ornamental grass picture attached. This is in your article but not clearly identified I live in an area with sandy soil
The image shows pink muhly grass and behind it, pampas grass. Here's an article on muhly grass:

I planted them 2 years ago and they have grown nicely and look healthy, but they are not pink at all. They look a bit cream color. Do I need to add a fertilizer ? Will that make them pink ?
I wonder if you accidentally got the white flowered variety? Do you still have your tags? (I always save mine). Fertilize in early spring and cut them back to make way for new growth. They also need as much sun as possible.
If it's not white, check your growing conditions against these:

Pink muhly has not been cut back in several years. Lots of dried material under the plant. Drooping over instead of upright.
Pink muhly thrives on neglect and only needs occasional trimming to keep plants upright. It's best to do any cleanup in spring before new growth starts, but you could do some light pruning now and save the severe cutting till late next winter.
You could probably pull out the dead material around it.
