During 2009, such is the vigour of the roots on Privet, the roots on my privet
bonsai had begun to grow out of the drain-holes at the base of the pot in search
of new space to extend into. They had grown to the extent that they formed a

matt of roots underneath the pot!
So in April 2010, as the new buds began to extend, I rootpruned the tree. The
bonsai was levered out of its home revealing a thick mass of roots that had
colonized the bottom of the pot.
As when repotting any tree, it was necessary to prune the rootmass. As can
be seen in the image above, when the bonsai is first taken out of its pot, it is
impossible to see which roots require pruning and which can be left alone.
