Knockout Rose Bushes

Shot Hole Fungus

Anonymous added on June 7, 2015 | Answered

Looks like pictures of Shot Hole Fungus on my Knockout Rose. First tried the baking soda and water treatment then purchased a mildew product. It got worse and now almost all leaves have the holes or some small white streaks. Should I cut the bush back since there is so much damage and hope it will try to recover these next few warm months we have in Tennessee? Thanks for any suggestions. Never did have the Green Thumb!! :(
