Answer: Japanese maples aren't really suitable for growing indoors. They need at least 4 hours of direct sunlight every day, and high humidity to keep the leaves from drying out. If they're in an air conditioned room, the AC will draw out moisture and the leaves will turn crispy. You can try to offset this by misting your tree 2-3 times a day. I'm just not aware of anyone being very successful growing maples indoors. Wish I had better news for you!
