This is about Photinia trees - maybe 10 - 15 ft tallThey got a [ ? Maybe ] red leaf spot disease. I used a Fore 80 WP . I did a lot of looking last year. It didn't go away. I trimmed all of them back to stems and trunks. Not a leaf left, but it seems to be back. Little spots spreading to adjacent leaves. Three of them [ trees ] died completely. The closest to the infection [ of last year ] the leaves are brownish and wrinkle e rather than the bright red as they've always been. Some have like a nibble ing track while some start as a dot. It seems to be spreading to the oleanders and some other bushes that I don't know what they are. It all started after a massive snow storm maybe 2 years ago. Help please, thanks Tom
