Spade size and the amount of water available
for your landscape should reect your choice of
tree size. An average root system will be about
the same size below ground as the branches are
above ground.
If no care is planned for the planted trees the
root ball should not be bigger than the size of the
spade; if some care is planned for the tree cutting
25% of the roots still leaves a 90% survival rate
and cutting 50% of the roots also leaves a 90%
survival rate if very good care is planned.
If you live in a dry environment you need to provide
more water to ensure fast growth. Fast growing
trees will have a better survival rate then slow
growing trees.
Selection of trees also depends on the desired
eect and the purpose trees will satisfy in the
landscape.
Will they attract birds to the area?
Shade a patio?
Screen an unsightly view?
Enhance the view of the home?
Identify an entrance or exit?
Trees should provide contrast and relief from
surrounding buildings and create seasonal interest
in areas near the home.
6�1 Planting Procedure
Transplanting is not successful until the tree returns
to a normal growth rate. This transplant recovery
period normally takes three years, but may range
from two to eight years. To get the most satisfactory
performance from trees, attention must be given to
planting details. Using quality plants and following
good cultural practices such as watering, pruning,
and fertilizing will not compensate for poor planting
techniques or poor plant selection.
Try to position spade at same angle (right/left)
when digging and planting so the ats on the
blades match, this will leave less air space under
the root ball.
When lowering the rst trees take a close look or
have someone with you to insure root ball is well
centered because if it is released o center the
root ball will drop and tilt and it could damage the
tree roots (it is easy to get a feel for it after planting
a number of trees).
Raise blades one inch each until the root ball
seems lose then extract each blades completely,
if the tree is leaning raise the blade that trunk is
leaning towards rst, this will spin it up a little. If
you are transplanting without baskets do not try to
twist, spin, or move the root ball; just leave it and
within a week try staking the tree if it is tilted.
Use water to settle the soil around the root ball.
Mulch two to four inches deep with woodchips,
bark mulch, or other suitable mulch.
Trees should be pruned to remove broken,
damaged, or dead branches.
6�2 Care For Your Trees
You should consider each of the following as
important in caring for your trees:
• Fertilizer
• Mulching
• Watering
• Pruning
• Staking and guying
• Tree wraps
6 WORKING WITH
TREES
19

6�2�1 Fertilizing
Fertilizing generally is not necessary until the tree
begins recovering from the shock of transplanting
and establishes itself in its new home. This usually
takes at least one year in non-tropical areas. In
tropical and sub-tropical areas, this can take less
than a year to occur. In some circumstances, the
tree care company may recommend fertilizing a
recently planted tree.
6�2�2 Mulching
Mulching is very important for several reasons.
Functionally, mulches discourage weeds from
growing, conserve moisture during drought periods,
and allow better use of water by controlling runo
and increasing water-holding capacity of light,
sandy soils. Mulch also helps maintain a uniform
soil temperature.
A 3-4 inch layer of mulch can add to the aesthetic
value of a garden while protecting the base of trees
from being injured by equipment, such as lawn
mowers. Mulch rings also decrease competition
from lawn grass. Lawn grass, especially when
lush, robs trees of valuable nutrients and moisture.
Trees often are wounded by careless use of
yard equipment like lawn mowers, weed whips,
and other trimming equipment. These injuries
cut through important vascular tissue just inside
the bark, which can lead to decay and ultimately
death of the tree. A bed of mulch around the tree
eliminates the need to trim or mow close to the
tree’s base. Extreme care should be taken when
digging up or tilling the soil under a tree. Many
large and small roots will be cut by such digging,
especially if it occurs close to the trunk.
6�2�3 When To Apply
Mulch can be applied just about any time of the
year when trees and shrubs are being planted. The
best time, however, to apply mulch in established
bed areas would be in mid spring when the soil
temperature has warmed up enough for sucient
root growth. If applied earlier, the mulch will keep
the soil temperature lower and root growth could
be delayed.
6�2�4 How To Apply
It should be applied 2 to 3 or 4 inches in depth over
relatively clean, weed-free soils. Do not pile mulch
more than 4 inches. Identify and eradicate the
weeds before the mulch is applied. Keep mulch
pulled 12 inches back from the tree trunk.
6�2�5 Types Of Mulch
Most arborists consider organic mulches as the
most compatible with trees. Many organic materials
can be used as mulch. Bark mulches and wood
chips are the two most commonly used mulches in
most of the country. In the south, pine needles are
included in that list.
There are several inorganic materials used as
mulches. These include weed barriers such as
plastic that is sometimes used to discourage
weeds; however, plastic interferes with the normal
oxygen and water supply to the tree’s roots. When
the plastic is used, a very shallow root system is
created and during drought periods the plants may
not withstand the stress.
It is recommended not to use black plastic
around trees. There are several landscape fabric
“mulches” available that will function the same
as plastic, but allow for normal water and oxygen
exchange. These materials, sometimes called
geotextiles or weed barriers, are placed on bare
soil around trees and shrubs with mulches used on
