Apple Tree Rust and Cedar

Asked June 18, 2017, 12:19 PM EDT

I planted an apple 3 years ago and every year the leaves curl and get yellow spots. I spray in the spring with orchard spray and I have also used copper fungicide. Does not help. I have a pine looking tree nearby, but I do not know if it is a cedar and is actually causing the problem. Can you tell me if the pine is a cedar tree and is the cause of my apple woes. Also can you provide any information on how to fix the leaf problem.

Your apple does appear to have a rust disease. but it's not coming from the plant in the second and third photos.
Your evergreen is not a pine or a cedar, but a yew (Taxus), and a healthy good-looking one at that.

You have a red cedar, which are native, growing wild in a roadside field, or cultivated in someone's yard, and the disease can travel miles.

Take a look at this page, which also has links to a spray management schedule which must be closely timed and repeated to get what most people consider acceptable tree fruit in Maryland: http://extension.umd.edu/growit/diseases-apples-and-pears
