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.
