How To Grow Sweet Table Grapes

Caring for Young Grape Vines

My name is David Handley, I'm with the Universityof Maine Cooperative Extension, and we're here to talk about how to prune and traina young grapevine. This is a vine that was planted last spring. We got it from a dormantplant, or rooted cutting, and you can see the original part of the planting right here.This is what we got from the nursery, with a good root system under it. We planted it,and we had a bud break and some vine growth. This is last year's growth right here. Thiswas a green shoot. Typically, you may get more than one shoot developing. You may haveseveral buds on here. We want to prune this back to one strong vine, your strongest one.We're going to arrange for that to be tied

up to a trellis, because this particular vineis what's going to become our permanent trunk, or the permanent part of the plant that'sgoing to be with us for the life of the planting. We want to make sure it's the strongest ofthe vines that we can choose from. Any other one that developed that's very weak, we canjust cut that out, select our best one. The time of year to make these cuts are whenthe canes are dormant, and this is going to be really any time after the new year, untilthey bud out in late March, early April. We hope in the first year that we get enoughgood growth that we can tie it to the lower trellis wire.Typically here in Maine, we're going to be

pruning to either a four arm kniffin trainingsystem, or an umbrella kniffin training system. Those trellises consist of two wires, oneset at about two and a half feet, and a second wire set at about five feet.We hope in the first year that we're going to get enough good growth to reach at leastthe bottom wire, but in order to make sure it's growing straight, you can see we supportedthis with a small bamboo pole. Any kind of planting stake will work, and we just tiethat vine up as it grows, rather than let it grow along the ground where it can getrot problems, and not develop a nice straight growth like we want. We tie it up, just likeyou'd tie up a beef steak tomato, get the

growth that you want.As I said, we've got pretty good buds here, reaching up to the first wire. You can seethat I actually make it to the top wire, but you can see the growth up here is very scrawnyand spindly, and isn't really going to lead to a good, strong trunk. I'd rather actuallystart new growth for reaching to this top wire for next year.What that means is that I'm actually going to cut this off here, rather low, to try toget this bud here to break and give me a much stronger shoot to develop my trunk to thetop wire next year. I can just take that there, and then, instead of using the bamboo polethis year, I can just tie it to the wire.

This bud will hopefully break, and give mea good, strong shoot, that I'm going to reach the second wire next year. Of course, thesebuds lower down will also break, and if this one happens to be weak, I may select one ofthese. But, if this bud does turn out to be a strong shoot, I'll be cutting these offnext winter and getting my single trunk back up to the top wire.Next year, when this does reach the top wire, eventually what we'll be doing is taking oneyear old cane, and either draping it over this top wire and connecting it to the bottomwire in an umbrella kniffin, or we'll be taking one cane at the top wire on each side, andone cane at the bottom wire on each side,

to create four arms of one year old growth,for a four\uc0\u8209 arm kniffin system. Both systems work pretty well for concretetype grapes here in a cold climate like Maine.

Growing Grapes in Texas Jim Kamas Central Texas Gardener

I love Tait Moring's sense ofgardening style. Thanks so much for opening your gates for us. Right now we're going to talk aboutgrowing grapes. One of the hottest topics here in Texas because of all the wineries. We have Jim Kamas with us. It's great to have you back on theprogram. Welcome. Thanks, Tom, I appreciate it. Welcome back to Central Texas Gardener. You've just published a great new bookGrowing Grapes in Texas.

Congratulations on that! Thanks a lot. It took a couple years to get done, but I'm I'm pretty happy with it. Well you know, like I said, it's a hottopic. A lot of people are very interested in growing grapes in their backyard. Maybe one ofthose famous table grapes, like Concord or something like that. Well Concord ispretty tough to grow here. Concord likes acid soils which we don'thave. And it's much more adapted a cooler climates. If you wanted to grow Fredonia or some of the other lebrusca types, they'll work, but

Concord is a pretty tough one to grow here. Ok, well your book is filled with tips aboutvarieties and things like that. Let's focus on that home grower. You know , I know for example I go out to hillcountry every now and again to go to Fredericksburg, places around there. And I see wineries springing up like mushrooms now. And it kinda makes me wanna grow grapeshere in town. What does a home gardner need to know to get startedé Well if you're a homeowner and you want to grow enough vines to produce a little bit of wine

my advice is plant what you like. If you're planting a commercial vineyards we're going to have a very different discussion. But if you like Merlot, plant Merlot. If you like Syrah, plant Syrah. For smallscale, you have no big economicinvestment, so plant what you like and go with that. Yeah okay, that makes sense. In terms of the space needs, the sun,

all those kinds of things, grapes arerather particular and disease prone. Yes. So let's give people an idea of whatthe basics are that they would need to have any kind of success. Sure. Commercially our rows are spaced nine to ten feet apart, but in the backyard if you are maintaining the row centers with alawnmower or something, you can place the rows as close as six feet apart.And you can also go as tight as five to six feet between vines. You can put a lot of vines in arelatively small space.

So small space is OK. When we talk about the rows, we are talking about providing structures on which the the vines can grow and supportthemselves. Yes, a lot of times in California you'll see these free standing vines that are called head pruned vines. They don't do very well here because we need to keep our vines up off the ground because it rains here duringthe summer and they are very disease prone as you mentioned.
