Prune Grapes During Growing Season

Growing Grapes

We have plenty of wild concord grapes on ourproperty. However, the insurance company doesn't approve of our harvesting methods so it'sprobably best to plant some cultivated grapes. When I cleared the land for the greenhouse,it left plenty of area to plant various fruit producing plants which don't need the greenhouseto thrive. Plus why waste the space just growing grassé Taking a look at my 3rd grade drawing skills,I'm going to set three 4x4x10' treated posts 34 feet into the ground and space them 24'apart. This will allow for 8 plants in the space. Then I'll string 12 gauge galvanizedwire starting with the first wire 4246quot; from

the ground, then space the other two 12quot; apart.The plants can be spaced 6' apart and over time the vines can be trained along the 3wires. I had planned to set the posts first in theevent that I hit any large rocks while digging, however I blew a seal on the backhoe and hadto find some parts for it. So I took my chances and put the plants in first. The row shouldgo in a straight line and a 100' tape measure works well for marking out the locations ofeach post and plant. Jamming a piece of survey's tape at each mark does the trick. We're goingoldschool and using a pickaxe and shovel and digging a hole about 1 foot deep. Luckilythere weren't any large rocks in the way just

a few roots and small stones that the pickaxewas able to pluck out. Later, looking at the post holes, you'll see why I didn't dig themby hand. Planting the vines is fairly easy. I got theseseedless concord grapes from Gurney's for half price. I just remove the fiber that'sused for keeping the roots damp, spread out the roots a bit, and set it in the hole sothat all the roots that emerge from the vine will be just below the finished level of thesoil. All the dirt that came out of the hole was hardpan so I filled it with nice organicsoil, then compacted it down, and gave it a really good watering. It also importantto cover the area with mulch to help maintain

the moisture in the soil until the roots canget established. These will get watered every day for a couple of weeks. The actual work of planting the vines is quick.It's the preparation of digging out the rocks that takes all the time. A 30 cent Oring and a day to dismantle andreassemble the valve assembly and the backhoe is running again. I can now install the postsfor the wire arbor. It may not be the fastest backhoe, but it beats digging through therock with a pick and shovel. The holes are dug to about 4 feet which will provide a deepenough anchor to prevent the posts from leaning

from the future weight of the vines. Someof the rocks that I pulled out where bigger than the hole. If I had to dig these by hand,I probably would have only dug down a couple of feet, and then would have to anchor theposts with concrete and guywires. It seems like a really big hole for a post,but without an auger with rock drilling bit, it's probably the easiest way to set a post.A little cleanup at the bottom of the hole and it's ready. I'm using 4x4 treated lumberrated for direct burial. I'm not a fan of using treated lumber, but in order for itto last a long time, it's a necessary evil. I like to add two temporary cleats to thepost to help support it while I'm set it plumb

and backfill the hole. I also like to dropa few rocks around the base to hold it in place when I start to fill it in. I'll fillthe hole several inches at a time and compact it between each layer, then clean up the areawith some more woodchip mulch. The first wire starts roughly 4246 inchesfrom the ground and the second and 3 wires are spaced 12 inches apart. It will be theperfect snacking height for the deer. At each marking I'll drill a 38quot; hole through thepost and then put in a 516quot; eyebolt. The back side has a large fender washer and nut.Having a large washer will help to keep the nut from pulling into the post under the weightof the vines. It's fairly important to make

How to Prune Grapes Summer

Hi, I'm Tricia, a California organic gardener and today we're going to talk about summer maintenance for your table grapes we've had an extremely wet season thisyear and my table grapes have gone bonkers I'm growing four different types of tablegrapes here and there's a lot of vegetative growth making for a very densecanopy over the grape vines earlier in the spring, the shoots were thinned when they were about six to twelve inches long you should have about six to eightshoots per foot of canopy at the same time as thinning the shoots, I also cut the suckers off at the trunk

and i'm going to continue to trim these suckers throughout the season, as necessary you see there's not enough sunlight getting into this little fruit clusters the sunlight is what helps improve theflavor and the quality of the fruit by having so much foliage around thecluster, I'm also at risk for disease the first step is to take these long shoots and tuck them into the trellising and keep them out of the fruiting zone that helped a lot but you can see there'sstill a lot of hanging vines I'm going to trim back this shoot that has no clusters on it

if you're going to trim back a shoot that has clusters, be sure and leave about 1517 fullsized leaves before you make your cut cut as little as possible and try to cut atthe point where the leaves are half the size of the mature leaves these smaller leaves haven't startedproducing food yet so the vine won't miss them as much asit would miss these larger food producing leaves the grape vines are looking a lot better the cutting is going to stimulate the growth so you don't want to do this too late in the season if the fruit is just beginning to ripen,it's too late to cut

now that I've tamed the vines, it's time to thin the fruit cluster thin when the fruit has just setand before it gets too big for goodsized table grapes leave onecluster per shoot in order to improve the size of thegrapes, snip off the very bottom of the cluster I'm happy to have completed my summermaintenence on my table grape vines now I look forward to grape jam, grape jelly,grape juice, and those frozen grape treats so enjoy your grape vines and Grow Organic for Life!.

Pruning grape vines in Minnesota

gt;gt;TOM VAN DER LINDEN: It's spring in Minnesota,a great time to prune grape vines. Proper

pruning of grape vines means better grapes.And better grapes mean better wine. We'll cover basic pruning for a northern climate.For details on how to prune for your climate, check with your state university extension. Year one, we take the initial shoot and wetrain it into a trunk. Year two, we pick two healthy shoots and we train them to our trellis.We'll take the two healthiest shoots and train them on the trellis to form a cordon. We'llprune off the other shoots leaving just the trunk and the cordons. To review quickly,our first shoot we train into a trunk in year one, then in year two we take our two bestshoots and we train them to the trellis to

make cordons. Year three, the trunk of our vine is gainingstrength and circumference. We have cordons that are now trained to a trellis and offeach cordon we have new shoots. Toast yourself, you've learned three new terms.We have trunk, cordon and shoot. Now we'll learn three new terms, and then we'll moveon. The top of a trunk where it stops is calledthe head of the vine, and this vineyard for this particular grape the head is about fourfeet off the ground. You'll see vineyards where the head is higher or lower dependingon the use of the grape, the kind of trellis they're using. So it'll be okay to have differentheights.

In spring, a new green shoot grows from ourcordon. And now after the leaves have fallen in the fall, the shoot becomes a cane. Forspring pruning, we're going to take last year's cane, and when we clip it again, it will becomea spur. Working on a little older vine, here's thehead and the nice, thick trunk. We have a cane, and then a spur, and then a cane, andthen a spur. Don't worry, you'll soon get the hang of it. Taking a closeup look, we have the cordonhere, and we have a shoot from last year coming off and we need to shorten the shoot now inspring to make a spur. so that we can control

our fruit load. Let's count buds: we havea bud here, we have a bud here, we have a bud here, and we have a bud here, and so forth.On some varieties, this bud close to the cordon is not fruitful so we won't count those buds.We'll count first a bud here and a bud here and make our cut out here. In other varietieswe will need to count this bud as one, two, and we'll make our cut here. Whatever youdo, you'll want to keep good records so when you go back into your vineyard you can seehow the fruit responded to your pruning. So let's count the buds on this cane. We haveone, two, three buds, and we're looking for two. So we have one bud, two buds, and weclip there.

We need to prune this vine to control boththe fruit load and the sun exposure. It's important in a northern climate to get goodsun exposure on your grapes so that they ripen fully. This is a Frontenac vine that's growingand the cordons are growing along the upper trellis wire. So let's estimate the fruitload on this particular vine. We have seven fruiting spurs on each cordon, and each spurhas two buds. Now each bud will produce two clusters of grapes. We can look up the grapevariety we're growing and we can find out what an average cluster will weigh. In thiscase, they will weigh about four ounces. First, simply convert pounds of grapes toounces. Next, divide number of ounces by the number
