         PLANTING
     Most grapes are trellised and grown
in long, narrow rows spaced about 9-15
ft apart depending on training system.
Typically, there is 3-8 ft between vines
in a row. Muscadines have similar
trellises and row spacings, but are
planted 20 ft apart in a row
because they are extremely
vigorous.
Vines head trained, cane pruned,
and grown on a T-bar trellis
 TRAINING SYSTEMS
    Training refers to the permanent parts of
the vine, not the one-year-old wood. Two
basic forms are used, Head and Cordon. In
head training, the permanent part of vine
consists of trunk and some fattened stubs or
a bulbous "head" at the top. Spurs or canes
develop directly from the head. In cordon
training, the permanent part of the vine
consists of trunk and 1-4 long, straight
arms or cordons trained along a wire.
Spurs or canes are spaced at regular
intervals along cordons.
          PRUNING
   Grapes are pruned more severely
and methodically than any other fruit
crop. Pruning not only controls vine
growth, but sets crop load as well.
Without severe, annual pruning, grape
vines become tangled masses of
unproductive shoots that decline
in yield and quality very quickly.
A few important points:
  • Pruning is done in the late winter
when vines are dormant.
  • Pruning involves ONLY last year's
growth, or one-year-old shoots.
