This is my first attempt at wiring and shaping my new Juniper Bonsai. About 8 months ago I received this fabulous tree as a gift and I have been successfully maintaining its growth, shape and health . Now I would like to maintain the direction of the trunk growth. I wired the trunk as per the video directions and it looks good, but I did notice a bruise and some green/white scraping on one spot of the trunk. Do I need to do anything about the bruise or will it heal on its own?
