cane pruning is a very common way to
prune vines in cool climates and
especially here in Oregon most of our
Vineyards are uh can prunes just like
this this is uh before we would do
dormant pruning in the winter and what
I'm going to show you today is how to do
cane pruning for the intent to change to
Spur pruning so this Vine right here
grew the shoots from the cane that was
laid down last year it's already been
the initial printing Cuts were made
right here on the one-year-old cane
actually would be 2 years old at this
point and then all of these grew last
year so a cut here to remove this
initial cane that was laid down and then
another cut up here so I'm going to go
ahead and remove these
from from the canopy and the catch
wires the important part with making
that transition from a cane prune system
to a cordon train spur prune system will
look a lot like your cane pruning but
the difference is that you're selecting
your canes that will become the
Cordon in the following year so you're
essentially cane pruning with a more
deliberate approach to cane
selection and as I'm removing this cane
you'll see in cane prining systems
you'll normally wrap the cane around a
couple times so it stays secure on the
training wire but when we Cordon train
and spur prune we want to avoid doing
that in part because the Cordon will
eventually grow into that training wire
right
here so now we have a number of canes
that are here at the head and in prining
we always want to come back to this head
of the of the plant and or the head of
the top of the trunk but we also have to
look where our training wire is so
here's our training wire and we've got a
number of different selections here when
it comes to specifically choosing a
location for our Cordon we want it to be
below this training Wire by about 3 to 6
in probably 4 to 8 Ines depending on uh
what flexibility you have uh with your
pruning but you basically always want it
below so you can bring it up and train
it along this wire therefore these top
ones basically are no good so we'll
remove
those and there's two options
here and it really comes down to again
placement and direction for training
onto the wire these aren't absolutely
ideal uh but it'll work for this
example we're looking at producing two
cordons for a bilateral Cordon spare
tuned Vine and one of the key things to
remember when laying down the canes for
your Cordon is that you can wrap it
around the wire but this is only going
to be done for one year so this can
happen in this next growing season it
can grow but do not affix it with a
permanent
uh rubber band or twist tie you'll have
to come back next winter and remove it
once it's more alifi so that it doesn't
grow around this training wire and then
girdle
itself same is true over on this end
I'll just show for an example we can cut
off the laterals too
it'll look a lot like your cane
pruning laying it on that wire well you
would want to break it but laying it on
that wire wrapping around just once in
some cases people may prefer not to wrap
it all and you just put a rubber band or
flexible uh band over here at the end
but you just want to be able to place
your cordons well with the coming back
next season and removing it or
untwisting it from that
training training wire and ensuring that
you have better placement over time so
again we want to have it below our
training Wire by at least 3 to six or 4
to 8 in and then trained along that
training Wire by wrapping around once or
lightly and then removing that wrap the
following year
This video describes how to select canes for developing cordons in the transition from cane to spur pruned vineyards.
