Rose, Knockout Rose Problem with Herbicide

QUESTION:
This Knockout rose bush is 2 years old. Last spring it came out just fine. The pictures show how it looks this spring. The leaves won’t grow or develop. What can I do to get this rose bush healthy again?

ANSWER:
That looks like herbicide (RoundUp) damage!! My experience has been that the roses will NEVER grow out of this damage and should be removed. As Milton Glueck often says: “KISS IT GOODBY and enjoy the images you took of it last year!” You can plant in the same location; just be careful using the weed killers around ALL roses. For killing grass amongst the roses, you can safely use kills-grasses-ONLY products such as Grass-B-Gon, Fusilade, Over-the-Top, Poast, etc.

This is NOT Rose Rosset which can be seen at:
