That's absolutely not the point of the PDF.
I think you didn't read it.
The stress point system for BONSAI that
@bonhe has proposed is clear, concise, related to bonsai stressful practices such as repotting and wiring, and can be helpful to a lot of people.
I did read it and it is all knowledge we have all been told over and over and is common sense if you have been paying any attention at all.
We know repotting, pruning, wiring, heat, cold, too much water, not enough water all cause stress on our trees.
We know repotting causes the most amount of stress of the things we do to a tree purposely.
How many times have we been told or have told others the following:
With the exception of a few species, dont repot or do major work in the heat of summer
Dont repot and do major pruning in the same year/season
Dont do too much work to a tree in one season
Dont work a weak tree
Dont water on a schedule, water when the tree needs it
Protect the tree in cold weather, as though it was one zone lower than its stated USDA hardiness zone because its in a pot
Get the tree healthy and vigorous before doing major work
Dead trees dont make bonsai
IMO assigning points to tasks is dangerous runs the risk of someone killing their trees because they arent thinking about or really looking at the tree, they are just following a list on paper.
Like people that water every day instead of looking at the soil and learning when the tree needs water and then how to water appropriately.
Looking at a list and saying well these two things added up dont represent a high risk, but the person doesnt know enough to recognize the tree is already weak and does it anyway and the tree dies.
We need to actually look at our trees and learn when to recognize when there is a problem, not look at a list of stress scores on piece of paper.
That means actually looking at them every day, learning about them and thinking about them on an individual basis.
No list of scores on a piece of paper should ever replace your brain
