I have a papyrus plant that I've had for 2 years, indoors in a 5 gallon bucket. It used to grow wonderfully, so long as it had about an inch or so of water above the soil. In the last couple of months it has died off a bunch--it went from 20 stalks to just 4! And the 4 that are left, don't look so hot! They are browning on the tips, which I know is not a good sign.
I could have neglected it a bit and it dried out some, but the soil is always moist!
Any tips?

did you give it some slow acting fertilzer?
maybe the roots need divided?
i dont have papyrus, but there in one of my books, very pretty, do you keep yours indoors?
