Tree Ties
• Trees are attached to stakes
by tree ties. These come in a
variety of forms.
• If a guard is to be used, the
best ties are metal rings coated
with plastic
(below). These do not attach
physically to the tree but
encircle the trunk and prevent
excess movement. They allow
some movement and therefore
encourage the tree to support
itself.
However they can only be used
1m (3ft) or more from the
ground since all movement
near the root base has to be
prevented.
• Other ties usually consist of
rubber strips (below right).
These ground the tree and are
then nailed to the stake. A
rubber block is strung between
the tree and the stake to
prevent chafing.
• When staking close to the
ground, ties have to be tight
enough to prevent any
movement of the root-ball.
• Ties must be loosened or
removed as a tree grows. Ties
left too tight cause serious bark
damage, as they cut into a
growing trunk. Fast growing
trees, such as poplars and
willows, may need ties
loosening every year.
• Ties can usually be removed
after three years; but if the
guard is to remain for longer, a
tie will often be necessary to
prevent the tree from rubbing
against it.
Guards
• Trees are often damaged by
vehicles, dogs and people.
Tree guards help to protect
young trees but they need to
be maintained. Guards come
in various forms. Some are
made of a thin wire mesh. This
prevents animals stripping
bark (right) but offers limited
protection from vandalism and
vehicles. Plastic coated metal
guards are more rigid and
more attractive (see picture,
below). Both types are
attached to a stake with
staples. In particularly
vulnerable sites, heavy cast
iron guards may be necessary.
These are bolted to the ground.
