ID leaf spot on Rhodo
Hi, could use some reassurance please. 36" Rhodo 'Rocky White' planted last spring, from Lowes. Mounded for good drainage, overwinter with a mulch of pine needles, northeastern exposure but protected from winter winds. Pretty mild winter in these parts. It at first reminded me of Rust, but I didn't see any yellow spores, I think it could be chemical damage possibility from contractors who just do there job without regards for surrounding. They were spraying with a sealer type thing for brick chimney and grill protection.
I am sorry the pictures are so bad. If they don't work, I will try again.
Thank you in advance.
