Wisteria tends to be very leafy if the soil is rich and it flowers best in slightly dry, somewaht poor soil.

Pruning should take place in July/August shortening all whippy shoots to finger length, and winter pruning should just be tidying up.

Apply some potash fertiliser over the root area in March for 3 years. It will help to encourage flowers and will do other plants no harm.
