The evolution of plant health care parallels
human health care: from curing problems to managing health. Some arborists are
the general practitioners of plant management, others are
specialists.
Arborists who prune trees are specialists who play a
key role, not only in maintaining tree health, but also in managing risk. They
eliminate problem branches when trees are young so they don't become hazardous
when they are older. The result is trees that are safer, longer lived and
better able to stand up to storms than their neglected neighbors.
If you like to take a holistic, proactive approach to caring for
all plants in your landscape, investigate Plant Health Care (PHC) as an
alternative to typical lawn service treatments and crisis tree care. |

What Arborists Do
Arborists do more than prune and remove trees. They fertilize trees and
control pests, and they install cables, braces and lightening protection. Some
offer Plant Health Care, a systematic method of caring for all plants in the
landscape. Arborists regularly get training in tree care and job safety. Many
are business owners.
Some arborists specialize in tree pruning and
removal. They might even specialize in certain types of tree work, such as
climbing with a rope and saddle or working from a bucket on a truck. Rope and
saddle climbers can work on trees in spaces that are inaccessible to trucks.
Some companies only prune trees near electric lines. Some have the labor and
equipment to do emergency storm damage cleanup, others do not.
Arborists may provide pest control and tree fertilization services.
These treatments are appropriate when there is a diagnosed problem and the
benefits outweigh the cost--both the cost to you and the risk of harming the
tree or nearby plants. Before you hire someone to spread or spray chemicals on
or near your tree, be sure you understand what they are supposed to accomplish,
why it needs to be done and how it will affect nearby plants.
Arborists
use cables and braces to reduce the chance that trees with weak structure will
break apart during storms. When properly installed, cables and braces cause
little injury to the tree. Before installing cables or braces in a tree, it
needs to be inspected and pruned. Then the arborist installs cables high up in
the tree--two thirds of the distance from the weak branch crotch to the ends of
the branches. Braces are steel rods that provide ridged support for a weak
crotch. They are used WITH cables, not as a substitute. Once installed, cables
should be checked each year to be sure they are securely anchored, but not to
loose or to tight. Cabled trees need maintenance pruning at least once every
five years.
Arborists use lightening rods to protect trees and people
from lightening strikes. They also help protect the contents of nearby
buildings. Large trees that stand alone are most vulnerable to lightening
strikes. Large trees in parks, on golf courses, within ten feet of structures
and those with great historic or economic value are good candidates for
protection. As with cables and braces, lightening protection systems should be
inspected each year.
Plant Health Care (PHC) is a systematic method of
caring for trees, shrubs and lawns. It includes preventative care, frequent
monitoring, early detection of problems, and use of integrated treatments to
provide longterm, stable solutions. It minimizes crises and reliance on
chemical controls. Companies that offer the service of PHC make routine visits
to monitor the health of plants. They correct little problems before they get
to be big problems. In addition to caring for plants, they provide information,
suggestions and advice.
In addition to providing services to customers,
arborists invest time in training and business management. It takes many hours
of training and education each year to keep up with new arboricultural
information. Some arborists learn by attending workshops, others read articles
or watch tapes. Job safety training is routine for good arborists: working
around power lines; equipment operation; and tree climbing techniques. All
arborists invest time in business management. They care for equipment and keep
customer records. Some operate large companies that employ dozens of
workers. |
