When do you give up on a wisteria?
We inherited a potted one with our house that doesn’t flower. I assume it’s at least 4 years old as this is our 3rd summer in the house. It’s probably in a too small pot and generally looks a bit worn out. I’m indifferent to wisteria and wouldn’t choose it myself.
It’s in a sun trap that gets very very hot in the afternoon in summer. Is there any point persisting with it or should I give it a nice funeral on the compost heap and get a bigger pot and something more forgiving like a climbing rose?
