Root
Pruning & Root Barriers
|
A
good rule-of-thumb is to
remember that up to 50% of a tree is underground.
Also that the roots
will go
out more than the height of the tree. Using this,
we can see that the pine (seen to the
left) will have roots extending under the driveway
to the adjacent lawn.
|
|
These
roots were suspected to be causing
the lifting of this driveway. When cut‑outs
in the concrete were removed, this was confirmed.
The mass of roots is clearly visible (see photo
to right and upper right).
|
|
This
could of been avoided with a
root
barrier installed along the
left side
of the driveway. This tree can
still be
saved by pruning the roots
along the
left side of the driveway and then
installing a root barrier.
|
CAUTION
Large roots should not
be cut closer to the tree than 3 times
the diameter of the trunk.
Perferrably, a minimum of 5 times the trunk
diameter is best for tree health and stability.
An certified arborist
should be consulted before cutting large roots
close to a tree or large quanities
of roots on a single
tree.

INSTALLING BIOBARRIER
Using the Air-Spade,
compressed air is used to
dig the trench.
|
|
This exposes wires, lines
and roots without
damaging any of them.
|
|
Once exposed, the roots
can be cut. After cutting
the roots, the biobarrier
is
installed and backfilled.
The biobarrier keeps new
roots from growing thru it
and back into those
undesired areas.
