They are a menace! We have Oregon thornless which crops hugely despite
our hard pruning it every year, I know you are not supposed to but it is
the only way of getting in the fruit cage!


Every year I resolve to make the new growth into serpentine growths on
the wire but time and season's go past and I never actually get there
before they are too stiff to manoeuvre
