provide can enable a person to be a better and smarter consumer when
selecting a tree service to do tree work. Invariably, our
evaluation of bids and proposed
result in a lower total cost to the consumer because no unnecessary tree
work will be done. Be a good consumer. Become informed before you
buy tree services.
should begin at planting with broken, cracked, and severely damaged limbs
at first. There are valid
reasons to prune trees, such as reducing risk of failure, providing
structure clearance, reducing shade and wind resistance, and/or maintain
Proper tree pruning
removes no more than 25% of the foliage from a tree per growing season
including individual limbs. If you decide
to thin a mature tree,
make cuts primarily on tertiary branches, quaternary branches, and even
smaller branches toward the canopy edge only. A common malpractice
on large trees is removing many or all interior low branches less than
about four inches diameter. Industry professionals and many academics
consider this over-thinning or lions-tailing to be no more than an
income-generating scheme practiced by uninformed, untrained people
Urban trees do
not need to be pruned nearly as often or as much as most people (including
most Tree Care service providers and Landscapers) believe and/or say they
do. Many people (Tree Care service providers and Landscapers)
operate on the default principle that every urban tree should be pruned.
A more realistic default principal should be that 'mature
or over-mature trees should be pruned only for good reason.'
In California it
is a law that any service provided to the consumer that is priced above
$500.00 must have a valid California State Contractors License in the
category for which the service is performed. This means that if you
hire a Tree Service, make sure they have a C-61/D-49 Specialty Contractors
License, not a C-27 Landscaping License.
Also make sure the company you are hiring has membership in professional
organizations- such as the International Society of Arboriculture (ISA),
the Tree Care Industry 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.
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.
