After rootpruning the Privet bonsai; approximately 40%-50% of the
rootmass was removed in total. A Privet can and will tolerate much harder
pruning but for this particular tree, root pruning 50% of the rootmass was
sufficient.
The longest roots, and therefore the most vigorous, were pruned back the
hardest. Roots growing underneath the trunk were pruned back much harder than
those roots growing on or near the soil surface. The effects of pruning the roots
in this way is to balance out the strength of the rootmass as a whole by pruning
the most vigorous roots hardest and the weakest roots the least.
