The Q&A Archives: cannas

Question: I had to dig up some cannas for foundation work. They are still green. I live in Zone 6. Do I put them back in the ground until the first frost or just keep them in my garage?

Answer: I think I'd heel them in - either in pots or in the ground until frost nips the tops. This exposure to frost will signal the plants that it is time to go into dormancy and they will winter better if they can go through the natural process of ripening their leaves before their rest.
