Last year I bought some beautiful cannas. At the end of the season I dug them up, trimmed and washed them. I put them in my basement. They dried out and were not covered in pete or anythng else. Are they gonners or do I have a chance of haveing them grow & bloom? I believe I did this once before. I planed them in the ground and the grew very slowly. The didn't bloom until frost. If thats the case is there a way to jump start them. Can I soak them in compost tea and plant them in pots on the deck until they start to grow? HOw shlud I fertalize them to maximise and quicken growth?

Thanks for any advice!
