I am hoping someonecan shed some light on a problem I have! My peace lily is about 4 years old, is around 2 feet tall and in generally good condition. It sits in a north window where it gets plenty of filtered light, but not direct sun. The problem lies here: it likes to cry. Every morning when I get up, I have to go and wipe it's tears! There will be drops of (water?) hanging from the tips of most of it's leaves. I have asked around to people who have the same plant, and nobody has ever heard of this happening. What's going on? Help!
