I know you are happy with your purchase, but when you think of it: there is not one tree in the entire world that lives naturally indoors... There are species that live in warmer climates / tropics, and our homes are warm, but they also need humidity and ( most of all) sunlight. Plants "eat" sunlight, it is their sorce of energy, or food if you want. All these things you can not mimic inside. I have really green fingers, and struggle each year with my citrus tree when it comes inside. If you take the time to search this forum for dying tree/bonsai, you will find the same question by the dozens, if not hundreds...and I don't think I have ever seen one that comes back here to show how good and healthy their tree is doing...
