Highland blueberry?

Asked June 10, 2017, 9:01 AM EDT

We just moved into a new home and are unsure of these plants, so I'm guessing they are 10 years old. Are these three trees highland blueberry? They grow in full sun, are about 6' tall, leaves are simple, oval and alternate. They appear to be diseased with the leaves changing colors and the fruit appearing inedible. How do we care for the trees and remedy the disease? Thanks!

Baltimore County Maryland serviceberry trees rusts

The trees look like a serviceberry. This looks like a rust disease on the foliage and fruit. Rust on serviceberry can be disfiguring but does not kill the tree. However, it makes the fruit inedible. You did not mention if you are eating the fruit. Serviceberry is more an ornamental and the fruit is eaten by wildlife. Birds will eat the fruit.

There are preventative fungicide sprays labeled for ornamentals. You would have to spray about four times starting at the beginning of the season and throughout the growing season. You do not have to spray as this will not kill the trees.
