i have a wisteria that is planted over a deck and grows up and over a pergola. It has been in place for nearly 10 years and usually has hundreds of beautiful blooms and dense foliage. I cut it back to main stems every winter (usually in January). This year there is hardly anything on it - one meagre flower and half a dozen brown leaf fronds. I love this plant and it is a real feature of the garden and our main shade in the summer. I would be devastated to lose it.
Any advice very gratefully received.
I have one on the garage wall that hasn't got a single flower. A cutting taken from it on the pergola has lovely blooms. Both pruned at the same time. No explanation as to reason why. This year's weird weather maybe?
