my friend has a wisteria, which bloomed very well last year...this year
no flowers except one or two at the bottom...whats wrong?

Once your Wisteria has extended to the furthest point you want it you then
prune back all other shoots to two buds just after leaf fall (Christmas week
for me). This has to be done annually.
Any shoots that extend too far during the growing season can simply be
pruned back to a few buds and I do this a few times every season to keep
ours tidy. These then get a final severe prune to two buds (don't be tempted
to leave more!) during the winter like all other shoots.
What you are after are long permanent stems as a framework with side shoots
all along these stems that eventually look a bit like a stags antlers (or
fruiting spurs if you are a fruit grower) and it is from these you get the
flowers.
