Hi - I am new to growing flowers for exhibition, and have been growing sweet peas this year for a specific flower show on August 7th.
The judge there last year told me that I'd get the best results if I pinched out all flowers (i.e. stopped them flowering) until a certain time before the show, and then let them flower. Unfortunately I can't remember the number of days before the show that she suggested! It might have been ten days. Does this sound right to you? Or do you have any alternative suggestions?
With thanks in advance.
