Well, she got it mostly right. Thankfully, she does state it is necessary to destroy roses with the disease.

The acres of Knockouts used in landscaping around here has turned into acres of witches brooms. And no one is doing anything other than hard pruning to get rid of the growth. So far, about 80% of the KOs seem to be living just fine with the disease. The existing non altered canes continue to produce normal growth and blooms. And the affected canes produce monstrosities. The hard pruning that the blow and go guys practice rarely kills them. They just continue spreading the disease far and wide on the wind, with no one caring to do anything about it.

I've lot around 200 roses to RR.

I'm not planting any more.

It's too heartbreaking.
