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
What is Selection Massale How grape vines are propagated
This vineyard for example is thrity five years old. Now and again, vines are dying because they are too old so they have to be replaced by baby vines young vines. The idea is to do a selection massale and select the best woods we will use toreplace those missing vines. Here for example I have a beautifulviolent perfect vigor and the right of thickness of shoots.
What i do is that i'm going to obviously keep my two buds for next year's fruit, but also keep a section of the cane. which itself would have one two three four five buds.
The idea is to remove that cane when the sap will be a rising in late two winter early spring, and lay that shoot on the find tilth earth with only one bud coming out of the surface: the other four being undergound.
I'll leave that shoot one year, so that it forms or starts forming roots where the actual buds are. After one year we will take it out ofthe ground trim the new shoots to make them a bit more vigorous, and then back in the ground
to replace the missing vines. Selection Massale at work.
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.
