Why are my knockout roses ending up with branches of Victorian style?

I think you're wanting the same answers regarding your roses that I am. I planted two Knockouts about 10 years ago. They were pretty every year and would bloom all summer long until five years ago. They now have very few blooms and some of the branches are huge in circumference with red thorns all over them. Very ugly! The next door neighbor has the same problem. Maybe someone here will come up with answers. Sorry I couldn't help.

This sounds like it might be rose rosacea. If it is, it is fatal and there is no cure. I have lost several rose bushes of different types to this disease You might want to look it up on the internet to be sure.

Thank you Lazas. I looked it up and that is exactly what I have on my Knockout Roses. I appreciate your help:) Vickie
