I know nothing about roses. I think they smell bad and they tend to attack me when I get too close. But these little guys were healthy before the snow and now they are decidedly not. To my very untrained eye... It looks like powdery fungus and black spot. Am I right? And if so, how should I go about fixing it? The black spots are on both of the parent roses, and the powdery stuff on just one.
The trouble is, I am in the process of... Doing a thing to make more rosebushes. I've got canes from the larger of my roses bent over, partially buried, and am attempting to root them. (I figured since they're there, I may as well try and multiply them). Is a fix going to require me to start the process all over again? Because if that's the case, I'd rather just dig them out and replace them with something I like.
Thanks for any and all advice. I'm out of my depth here.
