We're getting there now.
Dude, I’ve repotted dozens, if not hundreds, of trees that are in nursery containers, transitioning them from those containers to bonsai pots.
I frankly don't believe this.
1. For the, "dude".
2. For the unsurity of dozens or hundreds.
3. And most importantly, because if it were true, with any majority being spruce, I doubt your educated stance would remain, "just cut them off".
On another note, this isn't a "nursery potted" spruce.
In all fairness and honor towards the material (which all our thoughts should be based in), this WAS a nursery potted spruce.
It will have a core indicative of such.
It's first pot, which only the original planter may know, Mrs. Schmikah may.
(Every stage between)
The pot Mrs. Schmikah repotted from.
Then this current square ordeal.
The roots are going to do exactly what that has had them do, which will also have to do with where the drain holes were in each pot.
The soil content will have mattered.
Most of that stuff, we do not know.
So my thing is, we can't know if those roots are any different from the .....
Yamadori would have long running roots which would have the majority of their feeders way out on the far ends.
Those long running roots couldn't have grown thru something they couldn't grow thru, so how do we know there are no feeders there? There was in the past.
How is a pot ALWAYS still providing an environment close to the core condusive to feeder growth?
In my experience, which, by level of observation can be greater than yours with no regards to length of study, once a spruce particularly, but Any tree really, moves on, as roots do when they circle, a whole host of things determine what the previous sections of root has done. It is never determined by my level of education, or yours.
If this...
, the tree needs feeders, there will still be feeders in the core of the rootball
Were always true, we wouldn't need HBR.
