d grafts where the growth
will be moderate, staking the first year is unnecessary, though it has
some slight advantages. In these cases, no pruning of any kind is
necessary until the winter following the planting, except in the case
of bench grafts. The pruning in the last case is confined to the
removal of the suckers from the stock and roots from the cion. If the
stocks have been well disbudded by the nurseryman, few suckers will
develop. In moist soil, the cion roots may develop vigorously and must
be removed before they grow too large, or they may prevent the proper
development of the resistant roots.
The removal of roots should usually be done some time in July. For
this purpose the hill of soil is scraped away from the union and after
the cion roots and suckers are removed it is replaced. In this second
hilling up, the union should be just barely covered so that the soil
round the union will be dry and unfavorable to a second growth of
roots. Later in the season, about September, the soil should be
removed entirely from around the union and any new roots that may have
formed removed. The union is then left exposed to harden and mature,
so that it will pass the winter without injury.
_First winter pruning._
At the end of the first growing season, an average good vine will have
produced from three to five canes, the longest of which will be from
two to three feet long.
Soon after the leaves have fallen in December or early in January the
vines should be pruned. The method is precisely similar to that used
for rooted vines before planting except that the main roots are not
touched. All the canes are removed entirely except one. This one
should be well matured, at least at the base, and should have
well-formed eyes. It is shortened to two eyes. It is well also to cut
off all shallow roots within three or four inches of the surface. This
is necessary in the case of grafted vines if any have escaped the
summer root-cutting.
Some of the vines may have made an exceptionally large growth. Such
vines may sometimes possess a cane large enough from which to start
the trunk in the way described later for the second winter pruning.
_Staking._
If the vines have not been staked before, the stakes should be driven
soon after pruning and before the starting of the buds.
In order to preserve the alignment of the vineyard, the stakes should
be driven on the same side of every vine at a uniform distance. The
