4 Year Old Bonsai
Just bought a 4 year old Juniper Bonsai, and am pretty excited to get started making it my own. Problem is, I have absolutely no idea how to do so. I've read blogs/forums/etc., but due to its age (and my naivety) I am concerned as to how much I can really alter its shape, without damaging the tree. For example, how big is too big to cut off branches, how many can I cut at once, can larger branches be shaped with wire, what is considered a large branch, etc.
I'm also in Toronto so am concerned about keeping it inside vs. outside as the temperatures can get pretty harsh in the winter (half of the year...) and don't want to shock it by taking it in an out. Any advice to what I can do right off the bat would be great!!
