I went out of town for 2.5 weeks, and my roommates didn't water my peace lily until yesterday (the day before I got back). It was doing really well before, had about 5 blooms and a lot of foliage. Now it's completely wilted, even though it was watered yesterday and I watered it again just now when I got home. The water seems to be running right through the pot even when I try to just drizzle it on. Is there anything else I should do like spray it? I'm so worried it's just dead since the wilting leaves don't seem to be getting any better. Help!
