Alan Titchmarsh's gardening tips

No blooms?

Q: Why won't my wisteria flower?

The questions to ask are: Is it a grafted plant? Is it on a sunny wall? Do you feed it, and do you prune it? If you've bought a grafted plant and you prune it in January (shortening all the side-shoots to finger length), and you also prune it in July (shortening all those long-questing growths to about a foot), and you've got it on a sunny wall, and you give it some rose fertliser in March... it should flower. If it doesn't, dig it up, throw it away and buy a new one, because you've got a flower-shy variety that obviously isn't doing well.
