Does anyone have experience with mondo grass?

I have some that I'm about to dig up. It was super easy but took a couple of years to fill in. I bought mine in 4" pots and split it up in to little plugs.

I had originally planted it in a heavy shaded area alongside my carport. The shade tree fell and now it's looking rough from the amount of sun it's getting.

Whenever I was moving it around I was splitting in to lil sprigs instead of planting the big clumps. Helped it cover quicker.
