roses with canker your remedies?
Dangit! I have a significant number of roses with canker...I've done a little research. Seems I need to cut 6" down from the brown, sterilize my pruners and follow up with fungicide.
I don't want to use fungicide. Is this going to kill my roses?
What can I (realistically) do to prevent it? Seems it is primarily on my grafted roses.
Thanks for any guidance!
