Umbrella Kniffin System for Growing Grapes
David Handley: I'm David Handley, with theUniversity of Maine Cooperative Extension, and we're here to talk about pruning grapes.Very simple system for farnorthern production. Here in Maine, we need to protect the vinesas best we can through the winter, but at the same time try to get enough light andexposure to the canes that we're going to get good fruit set, and good fruit quality. One of the systems you can use for labruscatype or concord type grapes, which are the ones that do best here in Maine, which isthe umbrella kniffin. As opposed to the four arm kniffin, the umbrella kniffin puts allof its canes up at the top, or the first year
growth that's going to fruit. What we're talking about with cane growthhere is one yearold growth that has a chocolate brown color, and nice smooth bark with budson it. We're going to be saving four canes, plus the permanent trunk, to give us all ofour fruiting structure. Everything else is going to be coming off of here, and that includesanything that fruited last year. You can tell the two yearold canes, or thecanes that fruited last year, because they'll be thicker, and they'll have gray, peelingbark. All of these are going to come off, and we're going to save the one yearold canewith the chocolate brown color, and the smooth
bark. The first step in pruning is to look at ourpermanent trunk and remove all of the two yearold growth, the growth that fruited lastyear, saving a few canes that we'll be using for fruiting this year. Our first step isto cut some of these off, looking at that older bark there. We just cut that out, getit right out of there. This will open up the planting, and that twoyearold wood is not going to fruit. Unless we take it out, we'll find that our fruitingwood gets further and further away from the trunk. Part of the reason we're pruning isto keep that fruiting wood concentrated right
near the trunk. With the umbrella kniffin, which is what we'repruning to here, we're only going to maintain four of those fruiting canes. We want themall concentrated near the top of the trunk, or the top wire on our twowire trellis. We'regoing to take each of the canes that remain behind. As you can see here, here's my nicefruiting cane, smooth bark. All these are buds that are going to breakand give us long, green shoots that will have bunches of grapes on them. We're going todrape them over the top wire, and then we're going to attach them to the bottom wire, togive you that kind of quot;umbrellaquot; look, thus
the name of the system called the quot;umbrellakniffin.quot; Then we're going to cut off the ends of thecanes, so that there's only about 10 buds on each one. We just count those from thetrunk. One, two, three, four, five, six, seven, eight, nine, 10. If I need to leave one ortwo on there to make it reach the bottom wire, that's fine. I'll just go to where I can attachthis to the bottom wire, like that. I need two for the other side, to completeour umbrella. You can see this leaves me with several other fruiting canes, and I need tosave some of those as well, but they don't need to be as long. What I'm calling theseare quot;renewal spurs,quot; because we need the buds
from these shoots to come out and give uscane that we'll be able to put up on the wire next year. For every fruiting cane that I'm leaving behind,I also need to cut some renewal cane, or renewal spurs, to provide us with fruiting wood fornext year. I just cut these back to one or two buds, and if they're not where I wantthem I can cut them off completely. But for every fruiting cane, I need to leave at leastone renewal spur. I tend to leave a couple of extra renewalspurs here in Maine, because I'm very sensitive to the fact that I'm likely to get winterinjury almost every year.

High Density Espalier Gardener Grapes 101413
Ok this is the High Density Espalier Gardener and today I am showing you my High Densityplanting of my Grape Vines I have 10 Grape Vines here and they are allspaced 1.5 feet apart. I have a Perlette and a Cabernet and I planted these at differenttimes. First I planted 5 at 3 feet apart then I came back in and I planted others in betweenthose. This one is a Blueberry (Grape) apparently it has some sort of flavor of Blueberriesin it. This one is a Merlot. I have a Black Monukka, nice little grape. I have a Zinfandeland all of these have given grapes already except the Thompson's seedless, I am not surewhy it hasn't, but this one as you can see
has little grapes. Each one of these costsabout $25 at Home Depot or Lowes and I have pretty much made my money back on the grapesthat I have gotten back from these. This one is a Summer Muscat this one still hasn't givengrapes yet. Kind of a baby plant. Red Flame got a LOT of grapes from this one. As youcan see about 1.5 feet apart and I have a common row all along the bottom where I dugup the dirt and mixed compost in it plus fertilizer and I put a little rail (border) all aroundit so that when I water, the water stays in there and plus it keeps the grass out. Itis pretty much weed free. I have a Himrod, not sure if I said that already, and my Thompson'sSeedless. What I did was and you should be
able to see it on all of them, I am doingwhat is called Cordon Trimming (Pruning) and on the Thompson I've done a modified so thatIt has the long branches and supposedly these give grapes at the end of the branches insteadof closer toward the beginning on many of these other ones. I went over to Home Depotand I got these Green Posts. These are 8 ft. tall. Once they are driven into the groundthey're pretty steady and I got the wire, wrapped it around and it gets caught on theselittle things here so it won't fall down. Pretty steady holds up the plants quite nice.I should be getting a nice canopy over the top of them but even with the canopy it stillallows plenty of sunlight to go through. So
that is my little Mini Vineyard.
