Q.Photinia Fungus
Nikki-thank you for your answer to my question about fungus on photinia. Is there anything I can do to save my plant after it has been affected? Should I prune it severely? It seems to be still alive, but the foliage is all dead.

Treat the plant with neem oil. It is an effective fungicide and safe to use. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I would definitely prune and remove the dead growth and any foliage, especially that which may be on the ground. The diseased debris will need to be destroyed in order that the fungus does not reinfect the plant or infect any others nearby.
