Do the vines need to grow across and not up? I read that they fruit better when grown across but I hear about them growing up pergolas all the time.

Train them up, then across. If you want them in pots, put them on the side of a big pot. then put in a few star pickets and some reasonable gal wire. A cheap ($2) fencing tool will help with getting the wire fairly taught. then train as if it were in the ground. Its cheap and easy to pull up if you think of moving.

Here is a GA video on how to train and prune your vine (mid way down page):

For a passionfruit trained this way, I used some easy cement mix (just add water) with start pickets and wire. Don't go bunnings - go to a rural fencing supplier and pay half. To keep mine 'less' permanent, I cut a plastic drink bottle, put that in the hole upright with the star picket in the soil and filled the plastic bottle with concrete. That way I got a bit more stability but it would be possible to lift vertically out.

Note also to set the pickets a little outward facing so that tension in the wire will not bring them in too much (they do bend). I also used bamboo canes on some of my horizontal wire to reduce sag / tension due to the weight of the vine and fruit. See my edibles and the passionfruit 2 thread

I don't think you need a fencing tool. Just tug on the wire for tension then twist the ends around a few times, keeping them at 90 degrees as you do it or you'll introduce a weak point

Good one Brad - and Hayden don't forget to make sure that the holes in the star pickets are facing in the direction u want them too ;-)

Another thing u can do is get second hand galvanised pipe wide enough to take the star picket and pop that into the cement at ground level (make sure it doesn't fill up with cement tho') Then insert the star picket into that when dry - u can take the whole lot with u when u go!
(although it will leave a lump of concrete in the ground...and may be hard to tension the wire unless the pipe sticks out of the ground...) I use this method to get more height out of the tallest star pickets....

If you do go the star picket and gal wire option, one thing that i've found very useful for ensuring adequate tension on the line is a turn buckle at one (or both) end. That way you can set it up with out needing heaps of tension, and then tighten it to your satisfaction. You can also then tighten it further if it starts to sag a bit with time or the weight of the plant.

How do you guys go with the grape twerling around the wire, is it healthy for the grape vine or do you just tie it to the wire with a soft tie.

Hey ally.
just twirl it around the wire like this guy does in the video. That link BJ posted above is an excellent Gardening Australia segment on growing and managing grapevines.

Wow the video was very good. Thanks for posting that! That gardener was really hard on pruning and I guess I have to learn to be that hard to my grape vine too to make it more productive. Well my dog did that job secretly and perfectly last autumn by nipping the two leading branches off my caroline black rose grape vine right down to a stick that I thought it had died on me. It survived to my great relief!!!

Mine is in the ground. Attached pics. I tied a wooden trellis from bunnings ($10) to the stand of my pergola with some slip-proof rope so it can crawl upwards and then crosswards.

However after watching the video i think the grapes really can grow on a low level for easy harvesting and protection from looters such as birds and possums. Am starting to think I may have to change the trellis to wires on a lower level instead.

Can anyone tell me how long the lifespan of a grape vine is usually? I am very new to growing grapes. And without pruning, do they still fruit yearly?

Hayden, are your grapevines new? I had wanted to actually put mine in pot but I read somewhere grape vines in pot may not fruit. Not sure if anyone knows about this. Correct me if I am wrong. Thanks. Also attached a picture of pretty grape vine in pot. It must be quite mature and I do see bunches of grapes. :)

auOrey, grapevines live to a ripe old age, though I don't know exactly how long.
I inherited an old grape with a thick trunk, and I have been here 20 years. I have let it double in size by adding more support, and it is loaded with fruit.
I never water it, and it doesn't get fed either, just the mulch that gets thrown on it - weeds, dead flowers, scraps etc. So they are pretty tough once established.

Where I went to tafe there were some grapevines planted in the 1940s, all producing well, but not sure on what the longest they could go would be...

Grape vines are very long-lived (like olives). Apparently the oldest one known is in Slovenia, it is about 400 years old. I have seen the one at Chiltern in northern Victoria in this picture, which was planted in 1867. It is in the pub courtyard. Their tourist information says 'In 1936 it yielded a crop of two and half tonnes of grapes. With a trunk that measures 1.84 metres and a branch which is 12 metres long it is recorded as the largest in the Southern Hemisphere'.
