Devon, United Kingdom
I have recently moved into a house with a rather unruly wisteria that flowers and greens up at the same time. I have had to regularly cut back the quick growing shoots that have formed over the summer. I have looked at winter pruning regimes but as (my wife tells me!) it has remained green and growing over the last 2-3 very mild southwest winters, all I seem to do is encorage more whippy growth! Is it possible to prune it hard whilst still in leaf and will it affect flower production? This years flowers were in honesty a bit sparse. Any advice would be very welcome. Thanks in advance.
