Hi there, I am new to this forum. I live in Mass, USA. in zone 6-7. I have just recently taken an interest in Maples. I have two container maples currently. I have Pixie dwarf that is just a baby and a Tam that is about 3 feet tall. Both in containers. I just purchased a 12 inch Sango that should be coming shortly. Can you tell me what size pot to plant this in? Also, for my Pixie, its currently in a very small pot, probably about 8 -10 inch.. should it be bigger? (JM its about 4 inches tall).
