Plant
Health Care
The
most common reason a tree owner calls an arborist is concern that
something is
wrong with a tree. It may be that some of the leaves are discolored, a
branch
has died, or perhaps the entire tree has been dropping leaves.
Sometimes the
cause of concern is a minor problem that is easily explained and
corrected.
Other times the problem is more complex—with several
underlying causes and a
remedy that requires treatments extending over several years.
Unfortunately,
there are instances in which the problem has gone undetected for so
long that
the tree cannot be helped, and the only option is removal. If an
arborist had
been called earlier, perhaps the tree could have been saved.
The
Solution: Plant
Health Care
Situations
such as these led arborists to create Plant Health Care (PHC) programs.
The
objective of PHC is to maintain or improve the landscape’s
appearance, vitality
and—in the case of trees—safety, using the most
cost-effective and
environmentally sensitive practices and treatments available. Plant
Health Care
involves monitoring, using preventive treatments, and adopting a strong
commitment to working closely with you, the tree owner.
Why
Plant Health Care, Not Tree Health Care?
While
trees are dominant ornamental features in your home landscape, they
share this
area with turfgrasses, shrubs, and bedding plants. And all these plants
have
one resource in common: the soil. The roots of trees, shrubs,
turfgrass, and
bedding plants intermingle and compete for water and nutrients. In
fact, the
roots of a single mature tree may extend 60 feet or more out into your
lawn or
flower beds. Every treatment applied to the lawn (fertilizer and
herbicide, for
example) can impact the appearance and vitality of a tree. Conversely,
treatments applied to a tree, such as pruning and fertilizing, can
influence
the appearance and vitality of the underlying turfgrass. The
care of each
plant in a landscape can affect the health of every plant in that
landscape.
Why Landscape Contractor for
Plant Health Care?
Trees
and shrubs represent a considerable long-term investment in your
landscape.
With proper care, these plants can provide beautiful surroundings,
cooling
shade, and many other benefits for decades. Landscape Contractor have
the experience and
training to detect many potential tree and shrub problems before they
become
life threatening or hazardous. In addition, He/She can make tree and
shrub
recommendations, such as species selection and placement, to keep many
problems
from occurring in the first place. Landscape Contractor can also
consult with other landscape
services you may use, lawn care for example, to ensure that the
treatments are
coordinated and will not be harmful to your trees and shrubs. Remember,
the
potential size and longevity of trees and shrubs warrants their special
attention in your landscape. Bedding plants can be replaced in a few
short
weeks and a lawn in a single growing season, but it can take a lifetime
or more
to replace a mature tree.
What
Does a Tree and Shrub PHC Program Cover?
Every
home landscape is unique, so there is no standard PHC program. Plant
Health
Care programs do have features in common, however. First, PHC involves
monitoring tree and shrub health. This step allows problems to be
detected and
managed before they become serious. The monitoring may be as simple as
annual
visits to check on a few special trees in your landscape, or it may
involve
more frequent quarterly or monthly inspections of all your trees and
shrubs.
The monitoring frequency and complexity of your PHC program depend on
the size
and diversity of your landscape as well as your particular landscape
goals.
Second,
if problems or potential problems are detected or anticipated during a
monitoring visit, your arborist will develop solutions. The solution
could be a
simple change in your lawn irrigation schedule—many trees are
kept too moist—or
more detailed suggestions, such as pruning or spot applications of
pesticides.
Finally,
PHC involves you, the client. Your arborist will give you information
about
your trees and shrubs. This information ensures that decisions are made
that
address your concerns and are appropriate to your landscape budget and
goals.
Information may be provided through a variety of means. Obviously,
discussions
and answering questions are important means of conveying information,
but many
PHC programs include written recommendations after each monitoring
visit. Plant
Health Care is a program tailored to the needs of the client and his or
her
trees and shrubs.
How
Will My Trees and Shrubs Benefit from PHC?
Because
ornamental trees and shrubs can quickly succumb to problems, routine
monitoring
and timely treatments can protect your landscape investment and reduce
expenses. A monitoring visit to your landscape might reveal
- a
hidden infestation of tent caterpillars that may soon defoliate the
ornamental crabapples in your front yard
- a
weakly attached branch that may fail and damage the house
- improperly
pruned shrubs that are not flowering as abundantly as they should.
Your
Plant Health Care specialist can recommend treatments and changes in
maintenance practices that can eliminate these problems while
maximizing the
safety and aesthetic quality of your landscape.
What
Will a PHC Program Cost?
Because
each program is individually designed to fit the needs of a particular
landscape, no standard price can be given without a site visit and
assessment.
You may have an interest in developing a plan for a few key trees in
your
landscape, or you may wish to have the entire landscape placed on a
program.
PHC programs can also be structured in different ways. For example,
some
programs charge a fee for monitoring and bill each treatment
separately. Other
programs have an annual fee that covers all monitoring visits for the
season as
well as many potential treatments. These more comprehensive programs
provide
the peace of mind in knowing that treatments for most potential
problems are
already covered by the program without additional charges.
Individualized
programs and flexibility are at the heart of PHC. You will find that
your
Landscape Contractor can design a Plant Health Care program that fits
your goals and
budget.
