We have 3 different varieties of wisteria, all proper nursery grown plants that all had flowers when we bought them but we have never managed to get a single flower ever since. We have followed the twice annually pruning to the letter, tried all the different techniques we could find online, asked the experts at the Gardeners World show etc (feeding potash, treating mean, lots of water late summer) but all to no avail. We have 2 in large patio containers and 1 in the ground now and despite looking healthy and producing many buds for beautiful foliage, that is all we ever get! 2 neighbours have very old wisteria that appear to grow from under tarmac/concrete patio slabs who spend no time pruning feeding etc and yet they are now covered in flower buds about to burst forth!! Very frustrating!! We will wait in hope though that one day they will finally provide us with the amazing fragrant flower display we bought them for!!
