Other Services Pruning:
Your arborist can determine what type of pruning is necessary to
maintain or improve the health, appearance and safety of your trees.
These techniques include:
Eliminating branches that run each other
Removing limbs that interfere with wires, building facades,
gutters, roofs, chimneys, or windows, or that obstruct streets
or sidewalks.
Removing dead or weak limbs that pose a hazard or may lead
to decay
Removing diseased or insect-infected limbs
Creating better structure to lesson wind resistance and reduce
the potential for storm damage
Training young trees
Removing limbs damaged by adverse weather conditions
Thinning or removal of unnecessary branches
Improve the shape or silhouette of the tree
Removal:
Although tree removal is a last resort, there are circumstances
when it is necessary. An arborist can help decide whether or not
a tree should be removed. Arborists have the skills and equipment
to safely and efficiently remove trees. Removal is recommended when:
The tree is dead or dying
The tree is considered irreparably hazardous
The tree is causing an obstruction that is impossible to correct
through pruning
The tree is crowding and causing harm to other trees
The tree is to be replaced by a more suitable specimen
The tree should be removed to allow new construction
Emergency Tree Care: Storms may cause limbs or entire trees to fail, often landing
on homes, cars, other structures or other trees. The weight of storm-damaged
trees is great and they can be very dangerous to remove or trim.
An arborist can assist in performing the job in a safe manner, while
reducing further risk of damage to your property.
Planting: Some arborists plant trees and most can recommend what
type of trees are appropriate for a specific location. The wrong
tree in the wrong location could lead to future problems due to
limited growing space, insects, diseases, or poor growth.
Other Services: Many arborists also provide a variety of other tree services
including:
Practicing Plant Health Care, a concept of preventative maintenance
to keep trees in good health, which will help the trees better
defend itself against insects, disease, and site problems.
Fertilization
Cabling or bracing for added support to branches with weak
attachment
Aeration to improve root growth
Installing of lightning protection systems
Spraying or injecting to control certain insect or disease
problems
What is a Certified Arborist? An arborist by definition is an individual who is trained
in the art and science of planting, caring for and maintaining individual
trees. ISA Arborist Certification is a non-governmental, voluntary
process by which individuals can document their base of knowledge.
It operates without mandate of law and is an internal, self-regulating
device administered by the International Society of Arboriculture.
Certification provides a measurable assessment of an individual’s
knowledge and competence required to provide proper tree care.
Certification is not a measure of standards of practice. Certification
can attest to the tree knowledge of an individual, but cannot guarantee
or ensure quality performance.
Certified arborists are individuals who have achieved a level of
knowledge in the art and science of tree care through at least three
years experience and who have passed a comprehensive examination
developed by some of the nation’s leading experts on tree
care.
Certified arborists must also continue their education to maintain
their certification. Therefore, they should be up-to-date on the
latest techniques in arboriculture.
Selecting the Right Arborist for the Job
Membership in professional organizations such as the International
Society of Agriculture (ISA), the Tree Care Industry Association
(TCIA) formerly called the National Arborist Association, or the
American Society of Consulting Arborists (ASCA) demonstrates a
willingness on the part of the arborist to stay up-to-date on
the latest techniques and information.
Certified arborists are experienced professionals who have
passed an extensive examination covering all aspects of tree care.
Ask for proof of insurance and then phone the insurance company
if you are not satisfied. A reputable arborist will have General
Liability as well as Workers’ Compensation Insurance. Many
homeowners have had to pay out large amounts of money for damages
caused by an uninsured individual claiming to be a tree expert.
You can be held responsible for damages and injuries that occur
as a result of the job.
Ask for references to find out where the company has done work
similar to the work you are requesting. Don’t hesitate to
check references or visit other worksites where the company has
done tree work. Remember, tree care is a substantial, long-lasting
investment; you would not buy a car without a test drive!
Be wary of individuals who go door-to-door and offer bargains
for performing tree work. Most reputable companies are too occupied
to solicit work in this manner. Improper tree care can take many
years to correct itself and in some cases never correct itself.
Are you willing to take that risk with your valuable investment?
Good arborists will only perform accepted practices. For example,
practices such as topping a tree, removing an excessive amount
of live wood, and removing or disfiguring living trees without
just cause, are unnecessary.
Don’t always accept the low bid. You should examine the
credentials and the combination of price, work to be done, skill
and professionalism to protect your substantial investment.
Get it in writing. Most reputable arborists will have their
clients sign a contract.
Be sure to read the contract carefully. Don’t be afraid
to ask questions such as:
When will the work be started and completed?
Who will be responsible for clean-up?
Is this the total price?
If I would like more be done, what is the hourly rate?
