I've planted some wisteria and am trying to encourage it to grow up a wooden column. I put some nails into the column and have slowly wound the wisteria around the column on the nails and attached with twine. My plan is to wait until the wisteria has reached the top (where there is more to wrap around) and then remove the nails.
I've read a lot about wisteria but most of the articles about pruning it describe pruning to encourage flowering. I don't care at all about it flowering until it's very well established; instead I'd like it to grow as quickly as possible and as focused in growing up the column.
What should I do to encourage growth of the plant? Should I be pruning away the secondary vines and only leaving leafs on the main? Should I regularly fertilize? Extra watering or less water?
Thanks!
edited: I've added 5 photos. I don't know the variety of wisteria unfortunately.
1 The mature vine I have now. Trying to get the same effect.

4 Here's the end of the vine. If you look you can see tiny leaves.

5 Finally, I have a third plant that's less happy about growing up. As you can see it has a lot of sideways growth and new growth but the main stalk isn't growing.
