6.2.14 Protecting After
Pruning
In the past, part of the standard recommendation
was to apply a generous coating of a tree wound
dressing to all fresh cuts. It was believed this would
prevent decay-causing infection. Research has
proven that all of the wound dressings currently
available do nothing to prevent decay, and some
serve as a food source for microorganisms.
They also can hold moisture against the cut
wood, promoting the growth of decay-causing
microorganisms. A light coating of non-toxic wound
dressings can be used for cosmetic purposes.
6.2.15 Staking And
Guying
Guys or stakes should only be used when
necessary, such as when roots are not solid in the
planting hole or where the tree could be dislodged
by high winds. Bare-Root and Container Grown
trees are more likely to require staking or guying
than Balled and Burlapped trees. In most instances,
the weight of the root ball is normally sufficient to
hold the tree in place, assuming it was properly
planted. Research has shown that trees not guyed
or staked will actually become established and
grow faster than guyed or staked trees. It is best to
have guys or stakes professionally installed. Many
new products are available to the arborist so that
a long lasting tree guy or staking system that does
not harm the tree can be installed. Eventually guys
and stakes must be removed to prevent damage
to the tree.
6.2.16 Tree Wraps
Tree wrap should only be used when necessary. It
is usually reserved for thin-barked trees, exposed
trees, or trees in danger of rodent and mammal
feeding. Consult an arborist to determine if trunk
wrap is needed. If you do use trunk wrap, use one
made of new, synthetic materials. They generally
work better and are designed to avoid girdling the
trunk. Always remove tree wraps after the specified
time period to avoid damaging the trunk.
