HELP w/ Photinia - Leaf Spot Disease
I know my photinia has leaf spot disease. I am not sure how to treat this as I have read my different opinions. Do I use a spray on it? When do I spray it? Should I trim some of the branches away so it has room to breathe? I believe they were planted too closely.
Also now it doesn't have many leaves on it at all and the leaves that it does have, has the leaf spot. It does show a few new sprouts so I don't think it is dead. Any hints tips, etc would be great on how to take care of this shrub. We have 6-7 in our backyard near a fence as a hedge.
