I have a lovely strong healthy wisteria growing up the house. It only has 3 flowers on it (this is one of them). It might not sound like a lot but it's 3 more than last year.
We planned a wisteria at the front of our house a few years ago. It’s never done well as we don’t look after it as we should. Out house is white so needs painting every few years....plants growing up the outside are not a good idea. I have always wondered if it’s a good idea...we already have an ivy over the porch. ......they look lovely but not so good for house structures!
