They need to dry out between waterings. Not to the wilt stage, but to the dry
stage down about 2 inches into the soil. If at any time it wilts, water it
immediately. They also like to be fed once in a while. I use Osmocote in
containers for house plants. Put it in, and when you water the prills leach off
a small amount of fertilizer from the water dilution process. Brown tips on
spathe can also be from over water, underwater, over or under feeding, too much
light or direct sun, too hot, no aeration or air movement.
