Quiz: can you tell which side faced north for the last 5 years?
I fully admit I’m neglect in rotating my trees…enough that I built my bonsai garden with benches facing all directions so at worst, I could move them around and still see the front, while giving the trees a different exposure to the sun. Even then…
This hawthorn spent the last 5 years or more facing East, meaning it’s right side faced North, and it has resulted in a weakened right side. In early June, I moved it to a Southwest-facing position and gave it a good haircut. We’ll see how it responds to its new view.
Here is another example, an azalea that hasn’t been rotated in a few years, and the back is weakening. I don’t have any shots of the back in a weakened state, but the circled areas show where interior branches are dying, and the growth is sparce.
