So I inherited several Japanese Maples. Most of them are little more than seedlings and I will be letting them develop for the next few years.
However, about 4 of them are in a mature enough state to be raw material.
I want to start in with a first structural pruning. The problem is being unfamiliar with this species I have no idea when to do the first structural pruning.
I would imagine that right now (Sept. 9) would be a not so good time as the trees are fully foliated and building vascular tissue and saving up sugar and carbs for spring. But I could be wrong.
So my question is when should I do the first structural pruning? Now? After the leaves drop at the start of winter? In the spring? When?
What I want to accomplish is:
- Set the basic structure of the trees
- Preserve as much strength as possible for spring
- Not kill them over winter
