My Trellising
Was Completed July 1, 2003 |
 |
The type of trellising system is
important and may vary with your growing climate and grape
selection.
The fall is the optimum time to put your trellis system up. It's
even better to construct your trellis system the fall before
you even plant your vines. Well, I wasn't that
patient or organized, so now I have one year old vines,
needing a trellis system. I had better get
started.
There are dozens of trellising systems
used around the world, with each one suited to different
climate and grape varieties. The overall goal is to
get the vine up off the ground. This keeps the
vines away from the colder freezing air which may lie on the
few inches above the ground. I plan on puting in a
modified type of trellis system. Like many of
the grapes we grow, it can be considered a
"hybrid" I guess. I am going with a
modified Geneva Double Curtain and a Bilateral Three-wire
training system. Perhaps the trellis is the
same, but the training is different, I'm not
sure. The over all product will look like a
"T". It's that simple.
This is a list of the items I am going to need and
use for my trellising system. Keep in mind that each row has
16 plants spaced 8' apart. I put a post every two vines,
but could have gone every three vines.
 | End post - 6"-8" x 8' (4)
These are pretty much standard CCA treated fence posts.
I'll be painting mine white to add another layer of
protection to the post, but this is not necessary if it is
treated. Mainly this is for looks. |
 | Earth Anchors - (4) These are large
"screws" which auger themselves about three feet into
the dirt to "anchor" your end posts to. - Orchard Valley Supply
|
 | Row Post - 4"-5" x 8' (14)
These are pretty much standard CCA treated fence posts.
Steel fence posts can be used instead, however; I like the look
of painted wood fence posts. |
 | 10 Gauge High Carbon Wire - (1,000')
High carbon or high tensil-strength 11-12 gauge wire. I'm
going with 10 gauge since I expect the concord to have high
growth. - OK, I used the 10 gauge wire, and wish I would
have listened to Orchard Valley and gone with the 12.5 gauge
wire because the 10 gauge was so hard to work
with. Orchard Valley Supply |
 | Wirevise Tensioner - (14) These hold the
wire tight at one end and keep the wire from slipping under full
load. The wire can slip thru them one way, but not back. -

 | Wire Ratchet - This is a dandy little
item to help maintain tension on the wires. |
 | Grade 8 Rock - This is to be put in the
holes with the bases of the posts to ensure a solid foothold and
not sink or bend in the upcoming years. This is not
necessary, but I want to do this only one time, and to do it
right. Beelman

 | Vine Ties - These are used to tie the
vines to the new trellis wires. Orchard Valley Supply
has provided me with 5 different types to
try out. |
 | Tools - Shovel, post hole digger,
cordless drill, roll of string, level, tamper, large pliers,
crowbar, and a good cooler of water, because this my take a
while. |
Trellising system options
Here is a list of the different trellis systems.
 | Single Stake - used to grow the cordon (vine)
straight up along a stake |
 | One Wire Trellis - one wire strung between
posts at around 6' |
 | Two Wire Trellis - one wire strung at 40"
and the other at 6' |
 | Three Wire Trellis - first wire at 40",
second at 55" and the third at 72" roughly |
 | Lyre or Movable Wire Trellis - prefabricated
arms adjustable wire locations. The appearance of this is
similar to a football goal post. |
 | Geneva Double Curtain Trellis - one wire at
50" and the other two on the outer parts of a 30"
cross bar at the top of the post (72") making a
"Y". |
Well, first off, I put down string along the base
of the vines and drew it tight so I'd know where to dig my post
holes in a straight line. We dug the 18 holes and made sure they were all
right at 24" deep, so I'd have 6' of post out of the
ground. This sounds a lot easier and quicker than it is,
but this is mostly what I got done on Sunday.
We set the posts, leveled them (vertically) and
put grade 8 rock and dirt in the hole as we tamped it to make a
solid fit. I have not yet been able to put the wire up, but
did use the existing string and nailed it to the two end posts and
tied the vines off the ground at about 40" for now until I can
make time to get the wire strung. (hopefully later this
week). You want the vines off the ground so they
are not damaged by the frost.


I now have the posts secured, anchors
are in, and the first wire is mounted at 50 inches. I'll
be making a top crossbar or "T" in early spring and running
a wire on each side. This will give the grapes more
sunlight and air. Be sure
to check back often on any other progress.
Here's the finished product.... just 8
months later. :o)

It is best to consult your grape vine vendor to
see which trellising system they recommend for that variety. |
