Do you have to protect tree seedlings in pots for the winter?
I have small seedlings (Paw Paw & American Persimmon) in 1 gallon and in 3 gallon plastic pots (the typical black ones with holes for drainage). I live in NJ, which is USDA zone 6b. The pots are lined up on a pavement surface. Since the roots are not going bellow the surface of the ground as if planted directly in the ground, but are instead in containers which are directly exposed to the surrounding air temperature, will the seedlings be destroyed by the freezing temperatures (even down to -10 F.)?
