|Root pruning is
done in two instances.
- One when
repotting from one pot
to another, roots that have grown in a circle are trimmed to
promote future growth.
- Also, when planting into the
garden or landscape, a plant that needs root trimming.
A side effect of root-pruning is
that it increases the density of the
root ball. From every
root that is trimmed, a number of new roots will emerge from the
root-tip that was removed.
As the rootball is repeatedly pruned over the years, the
becomes denser and denser. Within a well-developed rootball,
dozens of fine
roots can occupy the same volume of soil that one unpruned
root may ordinarily use.
So though the size of the rootball is reduced, the volume of
root within a certain amount of substrate is sufficient to
overground part of a plant.
Root pruning does not
or stunt the plant in any way . The plant may lose a little
around 6 weeks after root pruning, as it
regenerates its root,
but after this short period of adjustment, the plant becomes
more vigorous than before as new feeder roots are able to
develop in the new soil.
