Q.I’ve pruned my Photinia at the wrong time
I’ve just pruned back my Photinia (end October) and realised this should not have been done after August!! Will it survive the winter or should I wrap it? It is well established and had become invasive but lovely.

I looked up average minimum temperatures for your area and it doesn't appear to get below freezing. So that is good news for your shrubs. The new growth should survive. New growth may be susceptible to a fungal disease, photina leaf spot, so I'm including information about that as well as pruning.
Also, if you pruned each stem all the way to the branch it came from, you shouldn't have new growth. Just trimming off across the top, however, will encourage new growth.
