Flowers on Evergreen Wisteria

Question

I have a wisteria growing up around a pergola. It’s lovely and green but has small flowers and not very many. What am I doing wrong? And also when to prune?

Answer 1

It may simply be in need of some phosphorus, which helps with blooming. Bone meal is good for this. This article will help as well: https://www.gardeningknowhow.com/ornamental/vines/wisteria/wisteria-blooming-problems.htm
