Small holes have appeared, and rust-color blemishes, on leaves of a newly planted skip laurel. Similar problems seem to be developing on a nearby newly planted oak leaf hydrangea. These plants have sun in the morning and some shade in the afternoon. Attached are images of two affected leaves on the skip laurel. Also attached is an image taken showing three small skip laurels the day they were planted, last month on April 3; the affected plant is the one in the middle. After the picture was taken all the new plants were surrounded by leaf mulch from the city of Takoma Park. They were about two feet tall when planted, and have grown a bit since then. Your advice on how to proceed would be much appreciated.
