Q.Japanese Juniper Wintering
I recently purchased two Bonzai Japanese Junipers and was to they should winter outside. I live in the Chicago area and it is late February and the soil is frozen. How do I treat these Junipers for inside storage? I am new to this Bonzai growing.

You do not want to care for these, indoors. They need a cold winter period to perform properly. They must be wintered outdoors. I would heed the advice given, and winter them outside.
