Picasso is new for me this year; it finally came up and started blooming. We've had major rain lately, and today I was able to take a look around the garden and found rust on it. I've looked through the forum, but I can't find any discussions on rust and cannas. Do I have to cut it back to the ground? Is that the only solution? I have other varieties of cannas in different locations, and of course I don't want them to get it (like I could stop that!)... I would greatly appreciate any suggestions.
