If its any help i kept my tree when i first got it in the conservatory, not good, it got scale insect.
So i moved it outside on the edge of the pond, where kids pllaying football broke the top off and knocked it into the pond.
After swearing and drying it out it has grown well, during the summer it lives in the garden away from footballs and in the winter it live in an outside cabin where temps can drop to 1 0r 2 deg but no frost. I have loads of leaves frozen and i take them fresh also.
