Do the same rules apply to a wisteria that I have trained into a standard?

last year I cut it back, this year it has got thicker but still no flower
Can you give me clues? I live in Jerusalem, the rocky hills of the Jordanian desert.
Wisterias grow quite quickly so every year ALL the ties should be replaced. Never use wire ties of any sort, use the thin green twine and have it in your pocket precut to about 10cms length. In your other pocket have some cut to about 20cms for thicker stems.
Put the twine round the back of the wire support, then cross it before tying in a double knot.
Do not ever wind stems round and round wires, trellis, etc. as it will either strangle itself or break the trellis!
See my 250ft long wisteria at www.wickhamplacefarm.co.uk
That photograph looks very like my wisteria - even the bricks are the same! It manages to break its wire support structure on a regular basis, and currently seems to be holding itself up by magic. It's set off round to the front of the garage now, and is clinging on to the garage gutter - probably not a good idea, I'm sure, but it flowers beautifully every year. I think I'd better go and check if it needs some attention
We inherited a tangled mess of wisteria on our allotment by the shed. Is there any saving it by pruning it back? It has never flowered but is abundant with lovely leaves each year.
