We are having a hot debate with our HOA over when to trim photina. We are located in Olympia WA. Last year we did a major trim in late March into April. I want to have our gardener trim about two-three feet of new growth off the top of the bushes now which is middle of May. We have one homeowner who has a "degree" in some type of horticulture and she is adamant that it is too late in the season. Our photina is treated regularly for leaf fungus, so it is very healthy. I feel that we could trim it at this time, but she is putting up a fight. Help!!!
If Photinia leaf spot fungus is a problem in your area, and it must be if you have yours treated, then it is best to only prune in the dormant months. Here is more:

One of my photinia is looking bad. The soul nearby seems wet even though we haven't watered for a few weeks, since we though we were overwatering. Can you tell what is going on?
It does look a lot like it has been sitting in wet soils. Typically, this plant cannot handle saturated soils for very long. Another thing to consider is that they will prefer a lightly alkaline soil.

Hi there I am looking for some advice. Last year at this time my lovely tree was luscious with flat green leaves so much so that I pruned it. This year all the new regrowth of leaves are red and curly, the green leaves don't look healthy and the whole tree looks red and unhealthy. It's an outside tree, the trunk is clean looks fine with no obvious fungus the only thing is on part of the bottom trunk coming from the ground is slightly darker than the rest of the trunk but could be discolouration due to soul being over it I don't know what to do. Would anyone have any advice?
The red growth is normal, which does make identification of the disease. This resembles Entosporum leaf spot. This is a common infection in photinia shrubs. I see signs on some of the leaves. This fungal infection is permanent, unfortunately. Preventing future spread is your only option. I would take samples to any local horticultural extension service, or the equivalent in your area the what we have in the US. They can test to make sure.
