I received some canna tubers from a friend. They did quite well during the summer. I am trying to remember if there were roots on the tubers when I received them. I have dug the tubers and have 6 times as many as I started with and the roots are numerous. I have been reading lots and lots of articles but not one has said anything about taking the roots off or leaving them alone. Normally, I would leave alone but, there are quite a few of them. Can you tell me what I should do? Thank you.

You can trim the roots if they are quite long, but it is best to leave them intact if possible. Here is an article on storing cannas that you may find helpful: https://www.gardeningknowhow.com/ornamental/bulbs/canna/storing-canna-bulbs.htm
