I would prune it back NOW. As already said, Photinias can be pruned 3 or so times a year. it encourages those red shoots. Give it a granular feed and water it well.
Dont be fearful of hard pruning....Photinias are often grown as hedging plants and therefore emenable to regular cutting.
Photinias are messy, leggy and fickle. I had 2 ....sInce removed....and currently have a dwarf and variegated variety. They look better on the nursery shelf than they do in the garden.
