Question
all leaves on our 8 foot diffenbachia have curled under slightly in the last 2 weeks. It's in a south window in Portland, OR  We have a 10 footer in the other room under a sky light. Please help us.
Thanks!

Answer
Carrie,

A diffenbachia plant does not like the sun. Move them away from the windows and sky lights. The leaves ccould be curling to escape from the sun or they could be curling from being over-watered.  It is not a swamp plant so it cannot sit with a drain tray full of water constantly. Empty the drain tray with a turkey baster an hour after watering it. It sounds like a beautiful plant. Good luck.
