Would A Laurel Bush Kill Of A Privett

Question

I have a very long privett hedge and the first bush died back so we replaced it with a laurel bush and then the next one did the same and so on and so on each time I replace it with a laurel bush any ideas why the privett which is healthy suddenly dies off?

Answer 1

Are the laurel bushes shading the privet? Sudden shade may have weakened them. It also could be the privets have a disease such as verticillium wilt that has nothing to do with the new laurels.
