Thanks for the information. I also appreciate the ideas. I have never grown a deciduous tree before, and it is very new to me. Bonsai in general is pretty new as well. I have spoken to people at several nurseries, and they have told me that although I will see the leaves change color in the fall, I should not expect a hibernation to occur because of the temperature down here. I asked if the tree would die and I was told that fertilizing on a regular basis will help to avoid that because a hibernation is a period of dormancy when the tree replenished its energy stores. The fertilizer will counteract the loss of energy. I will not be touching the tree for quite some time, and around here, in ground growing is simply not an option. The soil has high salinity and it is not fertile at all.
What about repotting? I have roots coming through the bottom of the pot. Do I leave them be, or do I repot it soon?
