Repotted Baby Trees

Question

I recently dug up 3 small young pine trees and pot them in pots. Should I leave these pots outside in the winter or bring them inside? Tallest tree is about 10 inches. The others are about 5 inches. I live in growing zone 7 (Philadelphia). Would like them to get bigger so I can then plant them in a more open area. Thank you.

Answer 1

If these are a native Pine species, then it would be ok to leave them outside. If this is not a native species, and is cold sensitive, then I would opt to keep them indoors for the winter.
