Garden Grape Trellis

Home Vineyard Growing Wine Grapes at Home

Hello and welcome to my home vineyard Let's get a lay of the land. As you can see thisis just a simple side yard it's got about 55 feet of space long twentysix feet of space wide we elected to go with twenty twofoot long rows northsouth facing uh. the rows are spaced about five feet apartto give us ample space for the vines to grow

and for us to manage and walk through we are planting about four plants per row to give it plenty of space to spread out and grow for the rows, we used uh. just simple fenceposts these are eightfoot fence post sunk about threefeet deep we tried to go about two feet deep butit wasn't uh. it just simply wasn't stable enough so we went that extra foot for stability

the wire is fourteen gauge wire uh. we elected to go with the verticaltrellising partly because it was easier and partlybecause uh. the north south facing rows, it allow it to get sun at all hours of the day uh. we have a drip irrigation linesran along the bottom we will be using half gallon per hour drips two per plant that allows us to adjust the water

water flow and manage the irrigation a littleeasier than if we used a heavier flow we'll actually be planting syrah grapes because we tend to be in a warmer, drier climateduring the summer doing something like pinot noirwould require greater cooler temperatures. that sort of thing that's our vineyard. We'll be planting the grapes nextweek and we'll come back then.

Basics of a Grapevine Trellis

I'm Lee Tyre with the Northampton CountyCooperative Extension Service, and we're going to talk about constructing grape vine trellises. A grape trellis is a structure that holds the vines off the ground, allowing sunlight inevenly, and making management and harvesting of the grapes easier. There are several different types oftrellises. What we've constructed here today is a very simple one, what's called a “highcordon grape trellis�. The grapes we are training to the trellis today are an Americantype, and they prefer to grow downward. So

what we've done, is we are going to trainthe cordons, the heavy limbs of the grape vine,along the top wire here, and as they grow, they'll send laterals downward. And we'llprobably come in later and add a second wire, here below it. As you can see here, older, mature vines canbecome quite large, putting a good deal of strain on the trellis. Since we want thesestructures to last for a long time construction materials is an importantconsideration. You want to make sure you use materials that are resistant to decay, andcan support the weight of mature vines.

Once you have selected your materials, it'stime to begin construction. When setting your end posts, make sure they are anchored well.With a short trellis, this could be a 4� by 4� post sunk 2 to 3 foot into a clay soil. With longer runs, or looser soils, settingthe posts in concrete or additional bracing may be required. With a long enough run, evenvery large posts like this one require extra bracing to help support the load. Of course, the last main part of a trellis is the wire. Again, you want to select a heavyenough wire to support your vine for years

to come. In addition to the wire, think about adding a device to allow you to adjust thetension on the wire easily. Wires will sag with time, and something like a fence linetensioner, a turnbuckle, or other devices, will allow you to quickly, and easily adjustthe tension on your vine.

Grape Arbor Trellis Update Spring 2016

This is what the grape arbor looks like inearly spring before it's ever had any trimming done. This is what it looks like about halfwaythrough the pruning process, getting it ready for spring, and here we are with it fullypruned and ready for spring to fully set in and the leaves to start to come out. So how have things really been going withour grape trellisé Well, you can see it here behind me. It hasn't really been a very bigproducer. That said, I haven't really put much effort into it. I haven't tried to fertilizethe plants in any way. I haven't put compost or manures or even any kind of blood mealor anything like that on them. I've just let

them be, so I don't know if this is the yearthat they really blossom out and we really get a lot of grapes or if it's just not thebest setup. One thing I will say is that throughout the course of the year, you do have to goup there, maybe every two to three weeks, and make sure that the vines aren't growingonto the house. We only do the major pruning back to this once a year, but throughout theyear, every couple weeks, you've got to go up there and make sure they don't grow intothe house. So, if that's not something that you're willing to do or you don't have thecapability of doing it, then maybe this isn't the best setup for you to try. I think thisis probably limited to somebody who really

needs the shade. In our instance, you cansee that the land slopes away from our house very quickly. If we were to try to put somekind of a tree over here, first off it is also going to not just block the light, butalso be a storm hazard for our home, to have a tree so close to this side of the house.The storms would be coming from off camera this direction and would blow trees directlyonto the house, so trees aren't a good option for us. Having the trellis right up againstthe house still gets us the shade we need on this western front and not have our bedroomheat up. I think that's the other thing to consider. What part of your home are you tryingto shade. If this is a room that you're not

going to go into in the afternoon, then maybeit's not worth trying to provide the shade and the extra work involved with keeping thevines trimmed back throughout the year, so take those kinds of things into account tosee if this is an application that's really suited for you. Otherwise, the structure itselfis holding up really, really well. I was up there trimming back these vines and shakingit around and using it for support and it is flexible, because that's the way it's designedto be but I don't see any problems with it. I think if this thing were even in full fruitthat it wouldn't go anywhere, so I'm very happy with the stability of the structureof this kind of trellis.

Lastly, we are growing both table grapes andmuscadines on this trellis and one thing I'll note is that even though we're here in theSouthern United States and muscadines are our native grape, the muscadine vines aremuch more fragile. They're much more likely to break. They're more brittle. The tablegrapes are very flexible and so what I'm trying to say is if I have a vine that starts growingat a diagonal that I wanted to grow at a horizontal, I can come back in the off season and cutthe tendrils off and move that vine down and put it where I want it whereas with the muscadinesI'm finding that as soon as I try to move them I'm more likely to snap them. They justget brittle and go way to dormant to try to

mess with them. I have to train them duringthe year while they're growing, whereas with the table grapes, I can train them right nowand don't have a problem with it at all. So, that's another thing that you could take underconsideration. So, we'll show you this again later as theyear goes on, but wanted you to get an update on the grape trellis. As far as the groundaround the grape trellis, we've got some plans for that too. Come back and see us again andwe'll let you know what's going on with that. Thank you all so much for watching. We'llsee you next time.
