Peace lily dying quickly - please help!
We brought home a big, beautiful peace lily 2.5 weeks ago. Since then it has very rapidly wilted, and we can't figure out why. We have only watered it when the soil felt dried out (which means once or twice per week), but it looked so sad by this week that I have stepped up the watering to every other day. We have also tried moving it into direct sunlight and indirect sunlight, but neither scenario has made any difference.
Should we move it into a bigger pot? Would it help if I tied some supports to its stalks? Is there any hope for reviving it at this point, or do you think it's too far gone?
I've posted some photos of the plant in its current state on my Flickr page (link below).
We're new to indoor gardening, so your advice would be very appreciated.
