I own a 6 year old Juniper bonsai. It has been in my care since the end of March 2005. In this time it has done very strange things. I beleive it is mainly due to my experimenting and getting used to watering.Its color has varied from light green to dark lush green to almost sickly brown. I beleive it is healthy because I have definitely noticed growth.
Just recently I left on a family vacation and left my bonsai in the care of my girlfriend for two weeks. When I returned it looked in better condition than when I left. I only stayed a a few days until we left again on a mission trip with my youth group. Now, one sub-branch(?) has turned an ugly dried-sage-green and my parents informed me that it had tiny webs on it.
I read some of the posts and was worried that I might have had a phomopsis or twig blight and proceeded to cut to see if the heart wood was black or even discolored; with no avail, the inside looked healthy? Any insight? I will try to post a picture.
