Dying Sedge

There are a few groups of large clumps of sedge in my garden, and in one particular spot one of the older (are they called "heads" of?) grasses got dug up, leaving a very large hole. 

I dug up some sedge from another part of the garden and moved it to the hole, where it died a slow death. Another smaller piece I moved took root and is now fully in place.

Recently a much larger piece of the grass (About 80cm diameter) was not needed, so I dug that up and put it in the bare patch, which it completely filled. However, I can already see the ends of the grass going steadily whiter and I am afraid it might die there, too- why is this? And can I stop it from happening?

    Thank you for your response, Verdun. That's a bit of a shame - the sedges look very good there all together. Is there something I can do to undo this? Can I dig up and divide again (the base of the grass is very solid - the whole plant out of the ground has a kind of hourglass shape). Why shouldn't you plant a similar plant in the same hole?

    Because the original plant may have used up all the nutrients, or most of them.

    Thank you, Welshonion. I am not a well-educated gardener, so please excuse the naivety of these questions - but can you combat that by lining the hole with some fish and blood mix or some horse manure or something?

    I am tempted to congratulate you on kill a sedge! I'm forever weeding Carex pendula out of my garden! Do you know which sedge you have? Sedges in general prefer moist soils, so prehaps the soils been to dry for the roots to get established?

    Verdun thank you so much, that is all very encouraging and most useful. I understand about not replanting, but it's definitely the right plant for that place.

    As to the type of sedge, I'm afraid I have no idea. It's not sword - the leaves are much thinner and finer - but it looks a bit like it. A muddy green colour, brownish towards the tips. Does this help?

    Hogroast, back to your question about fertilizer.  It is best to scatter fertilizer on the surface of the ground and maybe fettle it in gently.  If you put anything in close proximity to the roots there is every chance you will burn them.

    IME Sedges don't need any fertilizer, unless you are growing a very refined, special one.
