Hello!

Winter is near and I am not sure how to prepare. It is on my window on northen part, soo the sun wouldn't shine on directly. Should I take it farther from the window or should I do something more ? Some years might go below -20 C or even more and sometimes only -10. In the room is usually 18-20 degrees, but on the window might be less.

...if you tell us what "it" is we might give a helpfull answer. ( if "it" is a cat we could say you are in the wrong forum... )

Sorry i was so sure i wrout it. It is Carmona tree

Then winter is only lack of light, temperature is irrelevant
