Thanks Sue for that tidbit....if I had only kept them potted for a couple of weeks longer, the rust would have shown up and I could have isolated the plants. Lesson learned when getting new cultivars...isolate for the first season.
I clean the dead leaves and other debris from the beds every other day...hope this will help with any rust on the ground. Not sure how low the temps must get and for how long to kill the rust, but we should have a few more below freezing days ahead.
