May I suggest for your consideration the following?
"I always prefer to believe the best of everybody, it saves so much trouble." --Rudyard Kipling
Biological principles are the same for all living organisms. However, scale is very important in biology. Landscape trees are living more or less at the scale and in the environment in which they evolved, and to which they are thus adapted. Bonsai are living in quite different conditions from those in which the organisms evolved and to which they are adapted. It seems to me that the latter are much more delicately balanced at the edge of survival than the former.
