Knock Out Roses Yellow Leaves

Zone 8 | rosepedal added on March 11, 2013 | Answered

We have several Knock Out roses. They have some new growth but the old growth has yellowing leaves with black spots on them. What is this and is it a common problem? What should we do to remedy and keep it from reoccurring? Thank you!
