Help - correct way to prune Wisteria
I have had this wisteria Caroline for 3 years and have never pruned it, as I wanted to train it round this pergola. However I have read recently that you should prune July and February as it will encourage it to flower (which it hasn’t done so far).
As you can you see from the photos it is quite chaotic, and I don’t know where to start with pruning. There is no clear leading stem anymore either.
Any advice would be greatly welcomed!
