Pruning
Wisteria
Wisteria is usually trained high up walls, arches and pergolas, so you will often be working at height. Use a stable, well footed ladder or long reach pruners, do not overreach, and get someone to steady the ladder. Keep secateurs clean and sharp, since every pruning cut is a wound that can let disease in, so make tidy cuts.

Two-stage pruning is what makes it flower well.
When
Twice: Jul/Aug and Jan/Feb
How
Summer: shorten whippy side shoots to 5 or 6 leaves. Winter: shorten those again to 2 or 3 buds.
Notes
Be patient; flowering can take a few years.
