"Easily" is a subjective judgement. It can be done but the ease of the process would be for you to decide. However, I don't think it would be too much bother for you, given the amount of effort you put into your other projects.

@floral_uk z.8/9 SW UK How would most people use Star Jasmine on a fence? They would just let that plant grab what it can and own the entire fence?

I have absolutely no idea how 'most people' would use a Star Jasmine on a fence. It would depend on the people, on the fence, the location and what they want it to look like. You asked about training it on a wire and that is possible but you'd have to tie it in to start with and keep stray stems under control. It is not a prolific arial rooter, like ivy. It mostly climbs by twining stems.

Of course you can! Plant it over to one side of your trash cans and give it a vertical bar or three to grow wrapping/ twining UP., I wouldn't use wires, but rather 1/2-3/4" redwood sticks. Vertical sticks where you want it to twine up, then horizontal stiicks where you want it to go across the top of the fence.

We had star jasmine covering this fence about 4" deep flat against the fence for many years. A wall of green. When the fence had to be replaced, we cut the jasmine back down to the ground and put the grid back on the fence. The plant to the left of the lantern was an existing plant that I cut to the ground and has grown back. The plant to the right of the lantern against the fence was a one gal. can a couple years ago. It has taken a couple years to grow up, but I have had to train branches to go laterally so they will eventually cover the fence. They want to grow UP. If there is nothing for them to twine around, they will just hang out into thin air, Direct the growth where you want it. Snip snip every few weeks when you see any parts that are going where you don't want it to grow.

When we had the star jasmine completely covering the old fence, I just trimmed it with hedge shears two or three times a year, to stay about 4-5" from the face of the fence. Not exatly a tough job. I put old sheets on the ground in front of it and chopped, collecting the clippings.

Those redwood "lattices" are attached at the top and bottom rails of the fence, allowing about 3/4" or so behind them to tuck the vines behind as they grow.

@Babka NorCal 9b Where did you get a trellis that is so large? You said you attach the trellis at the top and bottom of the fence, but how are you attaching it? Nailing it in?

@Babka NorCal 9b I would like to find a way to "hang" the trellis on the fence, so that it could be easily lift off and then re-hung on a new fence, without any need to cut down the vine.

Hang it on U-shaped hooks, a few across the top, (so you can turn them horizontally to release the trellis) or use screws that can be removed when you want to pull it away from the old fence. But the fence guys will have to to work from your neighbors yard to put in a new one depending on the age and thickness of your jasmine vines you won't be able to pull it over very far. The older they get the less flexible.
