ine with a trunk of
about twelve inches, though this length can be modified slightly, as
will be explained later.
This cane consists of about seven or eight joints or internodes, with
an equal number of well-formed eyes and an indefinite number of
dormant buds, principally near the base of the cane or junction of the
one- and two-year-old wood. Only the buds on the upper half of this
cane will be allowed to grow. These buds--about four--should give six
to eight bunches of grapes and four, six, or eight shoots from which
to form the spurs at the following winter pruning.
With a vine which has been cut back to form a high head, the cane is
about twenty-four inches long and can be used to form a trunk eighteen
inches high, though this height can be modified as in the last case.
As with the shorter cane, only the buds on the upper half will be
allowed to produce shoots. These--about six--should give ten to twelve
bunches and the shoots necessary for the formation of spurs.
In all cases a full internode has been left above the top bud. This is
done by cutting through the first bud above the highest which it is
desired to have grow. This cut is made in such a way as to destroy the
bud but to leave the diaphragm intact and part of the swelling of the
node. This upper internode is left partly to protect the upper bud,
but principally to facilitate tying. By making a half-hitch around
this internode, the vine is held very firmly. If the swelling at the
node of the destroyed bud is not left, many vines will be pulled out
of the hitch when they become heavy with leaves and supple with the
flow of sap in the spring.
In tying the vines, no turns or hitches must be made around any part
except this upper internode. A hitch below the top bud will result in
a crook-necked vine, as the top will bend over in the summer under the
weight of the foliage. A hitch lower down is even more harmful, as it
will girdle and strangle the vine.
A second tie about half way from the upper to the ground is always
necessary to straighten the cane. Even if the cane is straight when
pruned, a second tie is needed to keep it from curving under the
pressure of leaves and wind in the spring. For high-headed vines three
ties are usually necessary.
For the top tie, wire is particularly suitable. It holds better than
twine and does not wear. Even though it is not removed, it does no
harm, as the part around which it is wound does not grow. The lower
