When our ‘specialist’ Wisteria pruner came to look after our Wisteria a couple of months ago, I told him how last year the Wisteria had been so bad because of the pigeons, who basically eat all the flowers. He said that there was a spray called Grazers which may work. We sprayed the Wisteria about four to five times in its growing season and thought you should have a picture of it as it is looking absolutely wonderful this year and its all down to your wonderful spray. Thank you. R.N. Hants.
