grape growing
Am looking to grow grapes and was considering constructing a trellis out of
1 1/4" galvanized pipe. I was planning on driving the vertical runs about 3 feet below grade(frost line here) and running 1 1/4" horizontal piping runs about 7 feet high off them. A few concerns came to mind.....the horizontal runs will be about 10 feet long....is that long enough? The vines will be trained along the piping. Due to the size of the piping will it tend to get too hot for the vines as the direct sun shines on them, thus burning the vines and leaves? I'm in the northeast. Thanks in advance. |

Hi Bob,
I saw the 3 foot deep frost and mention of northeast and wondered if you lived up here with me. Now I see your e-mail address and assume you are south of me. I live in the Adirondacks (Tupper Lake). I suspect that heat will not be a problem. Pipe of that diameter will probably prevent the vines from climbing by themselves. You will have to tie the vines up. Don't tie them too tight when they are young (just in case I'm wrong about heat not being a problem). When they get bigger, there will be a lot of shade from all the grape leaves by mid summer. If by chance, heat does turn out to be a problem, all is not lost. Keep the galvanized frame but string plastic coated wire between the uprights and tie the vines to that. I'm wondering if you have decided which varieties you will grow. Did you buy them yet? You are at least a zone warmer than here if you are anywhere near Albany. Even so, some of the good seedless varieties may be a little tender. Right now I have Interlaken (it must be over 20 years old by now), Venus, Reliance and Vanessa. I once had seedless concord but it was a weak grower and died out. I had, until recently, Canadice. I didn't like it and I got rid of it. I can grow all of those here because I prune them each fall and take them down off the trellis. When laid down flat to the ground, they can survive. Otherwise, they would die down to the snow line each year. I think Reliance is the best. It's a nice seedless red with good flavor. Vanessa is very similar with slightly smaller grapes and a very vigorous vine. Steve Bob wrote: Am looking to grow grapes and was considering constructing a trellis out of 1 1/4" galvanized pipe.

I'm compelled to say, if you live in the city limits, check with zoning folks to see if there are any rules as to the height of your grape support. I'm in the process at the moment (just called the code enforcement people this morning) with dealing with the issue that my posts are too tall, over 6' , because the jerk next door that the woman who lives there married recently, complained that they were too tall. They've been there for 10 years, and as soon as he saw a friend out there putting up braces to support the corners he was out there saying "you can't do that! You can't do that it's against the code" *sigh* He's taken it upon himself to complain about everything he can since he moved in.. hates me for some reason. Dun no if it's that I'm fat, or he took what I had said about trimming the trees growing into the phone lines as a threat. Just said I didn't know if they phone company could charge him for trimming if the lines caused an outage. Dun no, but he didn't trim them and I had an outage because of it. Anyway, I'm likely to have to cut them to 6' because of the twit. My father used to be the water master for a geothermal heating company, and often had to replace water lines where there were still chunks of pipe that was still sturdy, so he used 3 pipes to support the grapes on the west side of the back yard (those are going to be a joy to cut). One was just replaced as it had rotted off at ground level after 22 years or so. The exterior of the pipes was corroded with calcifications and such. So you might be able to roughen them and put some mixed up cement or plaster if it's really bothering you, but unless your sun beats down harder than this zone 6 high desert area does, I don't figure it's going to get too hot to bother grape vines. However, how long of a span are you planning to run these horizontal pipes before you put in another vertical support? Some of the grape varieties are VERY vigorous and it's amazing how much growth they can produce over the course of a summer! I have Himrods, a seedless green grape, that regularly puts out 20 to 30 feet of vine over the course of a year, and the weight load can get pretty amazing too when they bear heavily, particularly if you are like me, and don't get them pruned when you should ;-) Himrods can put out a lot of vine by the third year and start cropping then and every year after that. Himrods have long loose clusters, others like Mars and Venus have tight large clusters, Canadice have LOTS of tight clusters with medium sized berries. They too are vigorous vines. Their skins can get pretty tough if they don't get adequate water but they're pretty sweet. Concords and Ontario would be vigorous heavy producers. Interlaken often freeze to the ground as do thompson seedless grapes in my area zone 6. Some folks who live on the top of a hillside manage to grow them, as the cold flows down the hill away from them. But not here, the one year they produced anything they were smaller than baby peas. I dug them out. I used 10 gauge black wire for supporting the grapes run through redwood posts. Wire works well in that it does give a little if the grapes decide to hunker down and pull on it. I can cut the vines loose in the winter or spring .. stretch them a little, and they're good to go. They *might* pull down a more rigid support. I can't visualize the pipe size ..I know I know.. you told me but I gotta see it .. to SEE it ;-) Grapes are tenacious things that can surprise you with how much they can grow and how many grapes they can make. One season I think I gave away a pickup bed full..long standard pickup bed! I have one that is my favorite I started from cuttings from a friend's vine. In their yard it had seeds. In mine, it's been seedless .. except for the years when the growing conditions gave all the seedless grapes little soft seeds. That particular grape is soooo good that it floods the *entire* mouth, cheeks, roof of the mouth, and tongue with so much flavor it's just amazing. I gotta get some others started because the jerk that's complaining about the height of the posts supporting the grapes, is letting a black walnut grow right next to the fence where that grape is, jugulone put out by the roots could kill it. Good luck with your grapes, but check those city/county codes! Janice |

grape growing
Over the years, my biggest grape pest has been the grape flea
beetle. They wouldn't be so bad if they only ate holes in the grown leaves but they also arrive early. The early ones wait for the leaf buds to swell and they eat a hole and hollow out the center. Some years, I take a thimble sized amount of pesticide (such as Sevin) and use an artist brush to paint it on the biggest of the early buds. That doesn't answer your question. I'm just talking. Japanese beetles.... not too many years ago, I had never seen one around here. I was kind of hoping it was too cold for them to live here. Then one year, I found one. The next year, there were a few, then several, then a bunch, then last year, there were enough to actually do some real damage to the grape vines. Assuming the trend continues, I'll probably spray them with something this summer. I've never had the caterpillars. Do you have them every year or just last year? If they return, it would be interesting to find out exactly what they are and what they turn into when they grow up. How organic do you need to be? Are you willing to use a natural insecticide? Rotenone would probably be effective on both pests. Maybe an oil spray? There are horticultural oils mad from vegetable oil. If you want to use no pesticides of any kind, that probably only leaves a physical barrier. Have you ever used Remay fabric? You might try draping some of that over the top and sides of your grape vine during the Japanese beetle season. A few might get in under it but I bet most would just land on the fabric and wish they were inside. Let us know what you try and how it turns out.

It just crossed my mind that a Bt spray would certainly put a stop to the caterpillar invasion. Get some Dipel or other brand and get the kind made to be mixed with water and sprayed on. Don't bother with the dust on type.
