Keeping Your Trees In Tip-Top Shape
AMERICAN ARBOR CARE
Homeowners often ask us what steps they can take to keep their trees and shrubs healthy , particularly if they ’ ve already had a bad experience with a diseased or damaged tree . We ’ ve put together this list of simple maintenance tasks that can help keep your plants as healthy as possible :
1 ) WALK YOUR PROPERTY Get to know what your trees and shrubs look like and become aware of signs of distress . Take note if a once healthy branch is now discolored or has curling leaves or if you see insects or boring holes . During the growing season — April through October — look around your property every week or so ; during the winter months , inspections every three to four weeks should suffice .
2 ) WRAP YOUNG TREES Using commercial tree wrap , homeowners can work from the base of the tree up to the first or second main branch and tie or tape it down . There is great information available on the Colorado State University Extension website ( extension . colostate . edu ) on this and other related topics .
3 ) KEEP WATERING Even — or especially — when your sprinklers are turned off , you still need to water . We ’ re in a semi-arid climate , and warm temperatures over the winter can dry out tree and shrub roots , inhibiting nutrient absorption . We recommend watering every three to four weeks on days that reach 60 degrees or higher . Our watering guideline is five to ten gallons per diameter inch of the trunk .
4 ) PRUNE REGULARLY Pruning will promote growth during the spring and summer and keep your overall landscape looking healthy and tailored . Trimming also acts as a safety mechanism for keeping branches
8 shorter and stronger and better able to withstand heavy winter winds and snowfall . Be sure you understand the requirements of each species — some can take a heavy pruning and still flourish in spring while others require just a light trim to keep their blossoms intact . It also helps to bring an artistic eye to the process to create shapes that are attractive and fit in with your landscape .
5 ) FERTILIZE IN SPRING AND FALL In the fall , trees are working on pulling nutrients together to store for foliage and flower production for the following year , so fertilization helps shore up growth . In the spring , the trees ’ roots take the nutrients from the soil and apply them to important health-promoting functions such as root development and disease resistance . Use a blend of nitrogen , potassium , and phosphorus , with heavy nitrogen in the spring to promote growth and less in the fall to slow growth for winter . For mature trees , a professional arborist is your best bet to penetrate their large and complex root system .
We recommend that homeowners get to know a local arborist who can inspect their property yearly for harder-to-identify problems before they cause damage or spread to other trees . Be sure to ask about mycorrhizae fertilizers , which can really extend and improve plant health , as well as environmentally friendly treatments to protect your landscape .

AMERICAN ARBOR CARE
H
omeowners often ask us
what steps they can take to
keep their trees and shrubs
healthy, particularly if
they’ve already had a bad experience
with a diseased or damaged tree.
We’ve put together this list of simple
maintenance tasks that can help keep
your plants as healthy as possible:
1) WALK YOUR PROPERTY
Get to know what your trees and shrubs
look like and become aware of signs
of distress. Take note if a once healthy
branch is now discolored or has curling
leaves or if you see insects or boring
holes. During the growing season—
April through October—look around
your property every week or so; during
the winter months, inspections every
three to four weeks should suffice.
2) WRAP YOUNG TREES
Using commercial tree wrap,
homeowners can work from the base
of the tree up to the first or second
main branch and tie or tape it down.
There is great information available
on the Colorado State University
Extension website (extension.colostate.
edu) on this and other related topics.
3) KEEP WATERING
Even—or especially—when your
sprinklers are turned off, you still
need to water. We’re in a semi-arid
climate, and warm temperatures
over the winter can dry out tree
and shrub roots, inhibiting nutrient
absorption. We recommend watering
every three to four weeks on days
that reach 60 degrees or higher. Our
watering guideline is five to ten gallons
per diameter inch of the trunk.
4) PRUNE REGULARLY
Pruning will promote growth during
the spring and summer and keep your
overall landscape looking healthy
and tailored. Trimming also acts as a
safety mechanism for keeping branches
8
shorter and
stronger and
better able
to withstand
heavy winter
winds and snowfall. Be sure you
understand the requirements of each
species—some can take a heavy
pruning and still flourish in spring
while others require just a light trim to
keep their blossoms intact. It also helps
to bring an artistic eye to the process
to create shapes that are attractive
and fit in with your landscape.
5) FERTILIZE IN
SPRING AND FALL
In the fall, trees are working on
pulling nutrients together to store for
foliage and flower production for the
following year, so fertilization helps
shore up growth. In the spring, the
trees’ roots take the nutrients from
the soil and apply them to important
health-promoting functions such
as root development and disease
resistance. Use a blend of nitrogen,
potassium, and phosphorus, with
heavy nitrogen in the spring to
promote growth and less in the
fall to slow growth for winter. For
mature trees, a professional arborist
