I have 2, well established, 10ft photinia red robins. They have both flowered spectacularly well this year and noe the flowers have gone over. I need to reduce its size by a couple of feet and would like to encourage new red growth but this will entail cutting into old wood with little or no leaf growth. Your advice would be welcome as I do not wish to spoil these beautiful shrubs.
