Well, the light shouldn't be a problem unless it was in dim light before you brought it home (hiding in the back behind other plants?) and couldn't take the shock. Also, how dry is it in your house - if it's anything like the usual for your area, it's probably pretty low, so you want to get a big wide tray or something full of rocks under the pot, full of water, but NOT high enough to touch the pot or roots will rot - but it's a lot better than spraying 1-2 a day. Many plants will drop leaves in new locations (ficus is terrible that way), but don't overcompensate and overwater, because leafless trees can't use much water at all, so let a good 20% of the soil dry before you do it again. You might want to back it away from the window just 1-2' (again, don't overdo it) for a week, just to let it acclimatize a bit slower to the light. And give it a few weeks to recover and start growing new leaves. Relax, it's not dead (or shouldn't be) and it just needs some time.

Where did you get your Orange Jasmine from? I have been searching for over 2 months, but havent found any good (over 3 years old) Plants?

Thanks for your help!
