A
Tale of Two Trees - con't
... (

)
... the forest. Family B knew better. They realized that a tree in the yard
or along a street is not growing there because ecological sorting matched
its needs to the site. It is there because it was planted there; Nature's
method was circumvented. The new transplant is probably on poor soil that
is then subjected to the trampling of hundreds of footsteps. It most likely
is not enjoying the
optimum conditions of sunlight or shade, and it certainly does not have the
advantage of forest neighbors to shield it from wind, prune its lower branches,
and form the outline of its crown. In short, it needs help.
At Planting
Family
B also planted their tree correctly, but they also noticed a broken branch
and a branch that was competing with the leader. Both were pruned close to
the trunk. Another, swollen from the sting of an insect laying eggs (a gall),
was snipped off. Otherwise, all branches were left intact to provide maximum
leaf surface to manufacture food during the first year of life in its new
borne.

After
5-7 Years
Now
is the time to make a good tree even better. Lower limbs are pruned off to "raise"
the bottom of the crown well out of the way of human heads. The lowest limbs
are now the permanent lowest limbs. An important fact is recognized here. Branches
do not move upward as a tree grows taller. The center of a branch at 5 feet
will always be at 5 feet.
Higher up, a few overzealous branches are cut back so they do not protrude beyond
the graceful outline of the crown. A branch here and there is removed for more
even spacing but basically the job of sculpturing the tree is now complete.
After
3-4 Years
By
now root growth should he well on its way to anchoring the transplant and expanding
to the size necessary to nourish the growing branches. Family B decides to cut
off the root suckers and sprouts in the crown. Other excessive branches are
thinned to reduce competition for light, water and nutrients, and a co-dominant
leader is removed. A few of the lowest limbs are also removed, but others are
temporarily left to help the trunk develop more taper and strength.
Growth
is far enough along to reveal problems developing such as branches that rub
or are growing in an undesirable direction. Narrow angles are also eliminated
for reasons explained on page 4.
FAMILY
B's TREE -- Pruned When Young
15 Years After Planting
Family
B was amazed to see their tree survive a major wind storm one summer day.
While many other trees in the neighborhood suffered split tops and broken
limbs, theirs stood strong and firm. Proper pruning gave strength to the branches
and allowed the wind to pass harmlessly through the thinned crown. Early each
spring, the tree gets scrutinized and dead or damaged limbs are cut off using
proper pruning methods. Otherwise, Family B has only to enjoy the beauty and
shade of their tree. And what do you know? Just before they moved recently,
the real estate agent told them it was the trees in their yard that helped
sell the property so quickly.
