Rose Rosette Confirmation?
I have 5 Double Knockouts along the front of my house. Planted them in Srptember 2009. They are on the SE side of my home and have absolutely flourished. They are all around 6' tall and have put on a show each spring and summer.
However, I first noticed a few crazy looking branches last year and have just recently learned about Rose Rosette. If likes one of them is definitely affected, so I cut it down to about 4" stubs this morning. Below are some pics of one of the branches. There were probably about 5 or 6 branches that looked like this on a 6' tall by 5' wide specimen.
Am I right in diagnosing this as Rose Rosette?
Is it a given my other Knockouts ( that are in direct contact with the rose took down today) will be infected?
Before I remove the rest of the Rose, is there any chance it will grow back healthy?
Thank you so much!
