Monty said: “Just pulling off the old flower heads will help but by far the best approach is to use a pair of secateurs and to cut back to the first leaf below the spent flower.
“A new shoot will then grow from this point.”
He explained that some roses flower in autumn rather than the spring and summer period.
Monty said: “Of course some roses, especially the species bushes, have glorious hips in autumn and these will only develop if the flowers are allowed to set seed and fruit.
“So enjoy the flowers as long as they last and then wait for the autumnal display that they will produce from their fruit.”
