Just repotted the biggest 7 year old JBP seedling.
It turned yellow last year so I figured it stayed to wet. It was never properly repotted, only potted up into bigger pots. So I was afraid of what I might find.
This is the young jbp just before the operation.
Got it out of the pond basket teased all the soil out the roots on one side of the rootball.
The trunk measures 6 cm (2,3'') just above the roots. I want to let the top grow one more season and start removing it this summer, and select another continuation of the trunk next year.
I've always wondered if the lowest part of the trunk thickens any more when growing g out the next sacrifice branch? And if so, is this substantial or minimal?
The other side of the rootball was only teased out. There were surprisingly few roots on the bottom of the pond basket btw.
I found this repotting scary enough with a 7 year old seedling.
@Adair M Is this the way to go with my big black pine next year?
