Two forms of top are open to choice--the vase-form, or open-centered
tree, and the globe-form, or close-centered tree. In the first the
framework of the tree consists of a short trunk, surmounted by four
or five main branches ascending obliquely. In the second the trunk
is continued above the branches, forming the center of the tree,
and, later being headed in, a globe-like head is formed. In New York
the vase-form is nearly always chosen. In neither case is the task
difficult since the peach springs almost at once into tree-form with a
full complement of branches. Beginning with the second year the main
branches are shortened back from one-third to one-half their growth, if
heading back seem necessary, cutting to upper and inner buds so that
the oblique ascending vase-form is maintained. The pruning of the third
season is much the same, except that some of the interior branches
should be removed to open up the heads to air and sunshine. The third
season's pruning is repeated from year to year, having in mind that
the slow-growing, hardy, productive sorts can be pruned much more
severely than the free-growing, tender kinds. Open forks are a serious
menace and are carefully avoided to lessen the danger of splitting when
branches are heavily laden. About the most common mistake is that of
cutting out too much wood, thereby inducing so heavy a growth in the
parts that remain that winter-killing takes place; at best it makes
necessary continued heavy pruning for several seasons to keep the trees
in manageable size and shape.
Heading-in as described in the foregoing paragraphs is necessary
because the peach bears the bulk of its crop high up on its branches,
which are often broken by the weight so that after a bountiful harvest
the orchard looks as if a cyclone had swept through it. As the limbs
lengthen, too, it becomes increasingly difficult to pick the peaches.
Even with annual heading-in the bearing wood eventually gets too far
from the ground and the grower may have to resort to decapitating the
trees--an operation commonly known by the inapt term "dehorning." When
old trees are thus to be rejuvenated the limbs are sawed off during
the dormant season to within two feet or thereabouts of the trunk.
The tree will then form a new head which will in a season or two set
fruit-buds and bear a crop. The orchard may thus very often be renewed
or even re-renewed, lengthening its life by several seasons. In thus
decapitating trees, however, one season is always lost, sometimes two,
and the writer questions if it is not better to give the peach a "merry
life and a short one" rather than resort to decapitation to prolong its
days. Most growers may well throw dehorning into the rubbish-heap of
the not-worth-while.
