The theory
of grape growing in 1980 was aimed toward establishing a good root system.
Since land and vines were then relatively inexpensive, it was less painful
than it is now. Vines
planted were on their own roots. Meaning, the Zinfandel vines from Wente
were pruned in the winter.
A cane,
or section, of that pruned vine was cut to approximately 18 inches and
then planted in a nursery medium with almost all of the cane underground.
At
each bud along the cane that was in the soil, roots would form; the above
ground buds would form leaves. After a year the cane has a good root system
started. It is pulled from the ground, bundled in groups of 25, and sold.
The
canes are delivered to the vineyard site in the winter, and buried in damp
sawdust until the planting is imminent. While our canes were growing, Gino
surveyed the vineyard for the
layout of vines, water, and roads. Each spot for a vine was flagged. When
the canes arrived, he used a one-man auger to dig holes 24 inches deep,
following the flags.
As
soon as a hole was dug, the rest of the family followed. First, the roots
of each vine were trimmed, then it was placed in the hole, pushing the
roots downward (This may seem silly to mention, but many vineyards are
planted by crews who don’t push the roots down and they are plagued by
copious amounts of suckers forever after), soil was added, tamped down,
then more soil as the vine was heeled in.
Fratelli
Perata vines were planted at 520 vines per acre. This was the usual and
customary practice of the day. For us, it also meant that the natural rainfall
would be adequate for the vines, so we
wouldn’t need to supplement water during the growing season. And, being
on steep hills, the tractor could still maneuver through the vine row with
the rows 12 feet apart. Over time, the action of the vineyard disc would
terrace the hills, making tractor work safer.
The
newly planted vines were watered by means of drip irrigation: long black
tubes set out along the vineyard row, with emitters dripping 1 gallon of
water per vine per hour. This means of irrigation was developed in Israel.
It is the most efficient in delivering a certain amount of water to a specific
target and relatively little water is used.
Another
system that could be used is overhead sprinklers. Here, sprinkler heads
rise above the vine posts. When the water is turned on, the rotating sprinkler
head waters the whole area. This is useful if there are spring frosts,
as a grape insulated by ice can withstand temperatures below freezing.
Due to our elevation, our vineyard didn’t need this. Here, the cold air
simply flows down the hillsides and away from the vines.
Much
more water is used with overhead sprinklers than with a drip irrigation
system. Putting water to a shallow depth between the vine rows with overhead
sprinklers struck us as wasteful. As conservationists - farmers, we believe
in safeguarding the underground water supplies for future generations.
Dripping water to a smaller, deeper depth between the vines train the vines'
roots to go deep. These roots are less affected when Paso Robles’ summer
temperatures reach 100 degrees and more amd are deep in the soil where
water from the winter rains reach, not up near the hot surface.
After
the surveying, digging and planting, the irrigation tubes were rolled out.
Then the emitters were punched into the tube to water each vine. The grapes
were watered deeply, though
not often, their first year in the vineyard. Then wooden posts were carried
to the field, placed one per vine.
They
were hammered into the ground by hand using an iron cylinder.
This,
of course, is best done in rain softened ground, which meant carrying 5
or 6 or 7-7foot posts on our shoulder. This was before the 4 wheeler ATVs;
but remember, we were young.
At
the end of the growing season, each little stick had grown into a low bush.
The following winter, we chose the strongest cane from each vine to be
trained up the wooden post. The other parts of the bushy vine were pruned
away. Again, the young vine was watered deeply during the season.
The
trellis system was put up to support the next year’s growth, which would
be 2 canes growing horizontally about 36 inches above ground, forming a
T. One wire was placed to attach the cane, and then two wires were attached
higher on the posts to catch the vertical growth produced by each cane.
Over the years, new trellis systems were developed and tested. The system
we initially used has come to be known as “California Sprawl.”
Each
year, each vine required handwork, 520 vines/acre times 25 acres. Life
became cyclical, following the vines’ requirements. Winter, the vines were
pruned and trained. Spring, new growth meant tying the vine to the post,
then to the trellis wire when they were older. Summer, the young vines
were watered, a few acres at a time. Fall, the grapes are harvested.
