I have a one year old maple tree in a flower pot. I rescued this tree from my gutters, placing it into the pot with the material from the gutter. It survived the transfer very well and is now about 30cm tall.
The tree has been out in our side yard, in the sun, for most of the summer. The question is: what should I do with it for the winter? I am worried that the roots will be too exposed to the cold, being that they are not buried in the ground. Should I bring it in the house?
The tree is located on Long Island, New York. The winters are fairly mild here. If it survives the winter I am planning to plant it in the ground next spring/summer.
