when you get new vines in from a nursery or ones that you've gotten growing from
cuttings they're only going to be about this tall and they're gonna be basically
a little stick and one way to get them to grow straight up and onto your top
trellis wire is to use what's called a growth tube it's just a corrugated
plastic that wraps around the trunk and you can see one in place here which
creates a little bit of a greenhouse situation it's warm a little bit humid
it encourages that trunk to grow straight up and then once it gets enough
growth at the top of it you're gonna have vines that will grow out on to your
top trellis wire while the trellis wires need to be a pretty heavy gauge wire
originally I bought 12 gauge wire but I ended up having to get 10 gauge wire
because it was a sturdier wire that could hold the weight of the vine and
all of the grapes once the plants matured so I'm gonna take this off and
show you guys what a great start this vine has it's got a lot of leaf growth
inside that tube but all of that energy is encouraging that vine to grow
straight up and it will have a nice strong trunk as that plant matures if
you have questions about producing grapes contact your local Extension
Office or our researchers at the Sheridan research and Extension Center
that are researching grapes hardy enough for growing in Wyoming I'm Donna Hoffman
with the University of Wyoming extension and you're watching from the ground up
