My Prunus Serrulata ‘Kiku-shidare-zakura has been badly attacked by blackfly. A lot of it is dying. What should I do?

The greenflies can look bad but the damage is generally not all that severe. They will decline after a time and the worst is probably over. It is generally not worth spraying but this course can be taken using a garden insecticide if the damage is considered too severe.
