How to repot a young Japanese black pine (2 of 2)
One of my favorite repotting activities is often neglected. After removing the tree from the pot and working with the small roots (see part one of How to repot a young Japanese black pine) it’s time to improve the nebari. “Nebari” refers to the area where the roots emerge from the trunk – it’s the one part of the roots we can see from the outside. Good nebari conveys strength. A weak or unsightly rootbase can detract from the overall look of the tree.
We can improve the nebari by removing roots that don’t fit in for one reason or another, or by arranging roots in a more attractive fashion. For a young pine with lots of roots, I rarely hesitate to remove troublesome roots because I know there are better roots underneath. If the roots to be removed are bigger than what root scissors can handle, I use a concave cutter.

I have two of these – one for branches and one for roots. I’ve heard that this practice prevents the spread of fungus, though I don’t know how important this is. I like using separate tools for roots and branches because it’s easier to keep the branch-cutting tool sharp – the root tools must cut through soil particles – and I tend to keep my repotting tools separate from my other tools.
Some roots are easy targets. The small root below crosses directly above a root that grows directly away from the trunk.

After 5 years work on the branches it finally begins have some ramification.
