I appear to have a great crop of broad beans(windsor variety) this year. They are about 4ft tall with lots of flowers, though some have died off. Will they still pod? All of the books tell me to pinch out the tips to prevent black fly attack – I have cut off the top green growth over the flowers. Is this a correct interpretation of this advice? I have got nervous as I did have black fly last year.
It is not necessary to take off the tops until the black aphids arrive and it is done to prevent spread down the plant. That you have cut them does not make much difference.
