Christmas trees don't magically, or
genetically, aspire to a perfectly
peaked shape but rather take six to
eight years of careful pruning.

During the final month of the year —
and often, much sooner — vast
numbers of harvested trees begin
their migration indoors, where they
are festooned with ribbon, garland,
ornaments and lights.
Although these trees are grown in the
spirit of Christmas, they don't
magically, or genetically, aspire to a
perfectly peaked shape. "Once the
trees reach about 3 to 4 feet (1 to
1.2 meters) in height, we begin a
process called 'shearing,'" said Ben
Butler, farm and finance manager of
Butler's Orchard in Germantown,
Maryland, in an interview with the
American Farm Bureau Foundation
for Agriculture. "After the trees
grow in the spring and their new
growth begins to harden off, our
crews go through the trees one at a
time and help guide the shape of the
tree using a very long and sharp
knife."
The most common types of Christmas
trees are Douglas fir, Canaan fir,
Fraser fir and several species of
spruce or pine. However, out of the
630 species of conifers in the world,
the majority don't actually grow in a
strictly triangular shape, so trimming
is a crucial task when growing those
specimens meant to become Christmas
trees. This pruning process must
continue every summer until the trees
reach a marketable age, which usually
takes six to eight years.

Historical Tradition
So why do Christmas celebrants
demand pyramidal trees during the
holidays? The notions behind much of
the world's traditional Christmas
décor originated in northern Europe,
particularly Germany, where enduring
images and tales from the mid-19th
century still ensure sugarplums are
dancing through our heads and that
our Christmas trees are conical.
In that part of the world, evergreen
trees are pyramid-shaped for good
reason: Each needle-leaf layer has a
better opportunity to gather sunlight
for photosynthesis if the sun isn't
blocked by wide top layers. This tiered
arrangement allows the trees to
shake off heavy snowfall, and the
wide spaces between branches let the
winds whip through without causing
massive damage.
