Grapes -- Varieties -- United States; Viticulture -- United States
The second year's work is largely a repetition of that of the first.
The vines are permitted to reach the peak of the house and are again
stopped by pinching. A considerable number of laterals spring up on
each side of the main vine, and these must be thinned as they develop
to stand at the distance apart of the wires to which they are
fastened. This is pre-supposing that the gardener has chosen the spur
method of pruning, the method generally used in America and the one,
all things considered, which gives best results. The selection of the
laterals the second year, therefore, is a matter of much importance
since spurs are to be developed from them. Care should be taken to
have these spurs regularly distributed over the length of the vine.
This second year, grapes must not be permitted to develop on the
terminal shoots, but a few clusters may be taken from the laterals in
which case the laterals are pinched two buds beyond the cluster, the
pinching continuing throughout the season if the laterals persist in
breaking, as they will do in most cases. At the end of the season, the
terminal is shortened at least one-half, and the laterals are pinched
back to a bud as close as possible to the main stem. The vines are
then put down for the winter as at the close of the first season.
The work of the third season is a repetition of that of the second,
with the exception that the vine is permitted to fruit throughout its
whole length, although not more than one pound of fruit to a foot of
main vine is permitted. The plants are now established and the only
pruning in this and succeeding years is to cut the laterals at the
close of each season close to the main stem, leaving strong healthy
buds of which at least one, usually more, will be found close to the
stem. If more than one bud starts, only the strongest is chosen,
although often an extra one is needed to fill a vacancy on the
opposite side. After the third or fourth season, depending somewhat on
the variety, two pounds of fruit or more to the foot of the main stem
can be permitted. The novice, however, is likely to permit his vines
to overbear with the result that the crop is cast, or the berries
rattle, or the fruit turns sour before ripening. From the beginning to
the finish of the season, in this method of pruning, much pinching of
laterals is required. No hard and fast rule can be laid down for this
pinching, but, roughly speaking, all new growth beyond the second
joint from the cluster should be pinched out as fast as it shows. With
most varieties, this means that the lateral is kept about eighteen
inches from the main stem. After a few years, well-developed spurs
form at the base of the original laterals, and from these spurs the
new wood comes year after year.
