should be cut on a slant with the cut facing downward; this prevents water from

accumulating on the cut-surface. Cut the roots cleanly with a sharp knife to help
prevent rotting and accelerate healing.
Repotting
After the tree has been rootpruned, it is then necessary to place the tree back
into a bonsai pot. If the pot has not already been prepared, it should be done so
now.
Cover the base of the pot with a layer of soil creating a small mound where
the tree is to be positioned so that when finally planted, the tree sits just above
the height of the rim. Place the tree into the pot and ensure that the correct front
of the tree is facing forward. Tie it in firmly with the anchorage wires so that the
tree is unable to be rocked about by the wind in the coming weeks whilst new

roots are growing.
Add some soil and work it around the root mass carefully so that no air
pockets remain. Make sure that the soil is not compressed and take care not to
damage the roots. Continue to add soil until the pot is filled just below the rim.
When the soil is fully worked in, water the tree very thoroughly to ensure that
the soil is fully wetted and any remaining air pockets are removed. Watering will
settle the soil and it may be necessary to apply more soil to the surface. Re-water
until it is certain that the soil has settled fully throughout the pot.
Finally, the tree should be held in position by the anchor wires, not by the
soil.
