I have a peace lily in my office at work that gets low indirect natural light, in addition to bright white fluorescent light.
I have had it for about 12 months now. I have not potted it up, and it has always been quite root bound.
All that said, it was always the happiest green and healthy plant. It consistently got new foliage growth and sometimes almost flowered. It never ever showed signs of nutrient deficiency, and the leave were always a healthy green with a flawless complexion.
Then last weak it wilted like it was thirsty, and after watering it, it is not reviving. It is wilting now like it is heavily dehydrated, even though the soil is still semi damp from the last watering. Even though it is wilted over, and the stems are getting a little soft to the touch, the leave still have turgor and seems almost like they are not dehydrated.
I always watered it only when it got completely bone dry. I never over water.
I have no clue what happened. The only thing I could imagine is that last time I watered it, I much too heavily swamped it, and in a single watering I drown the plant. Is that possible??
This plant shows no signs of root rot, and has never shown signs of any maladies. Just one day it wilted and it won't revive.
Is there some other possibility of what went wrong?
