If they are too big to handle, you can split them into 2 groups or 3 groups. In the spring finish your splitting, put into some potting soil under lights, and see which ones come up. Those are the ones you want to transplant. If you don't split, they get too large, and tend to rot once indoors.

Thanks for the quick response, but there is still one thing I'm not sure about. Do I split in the fall when I dig them up, or in the spring before potting up? Also, when I split them, do I leave the raw area to harden and calous over before storing and before planting? Thanks again.

You can do either fall or spring splitting. They are different from dahlia however. My cannas I prefer to split in the spring when I can see the growing eye. If they accidently split ( or on purpose), I would let the wound harden, and then add the fungicide. ....just my thoughts.

Excellent advice! I will plan on splitting in the spring,let harden and then plant in potting mixture and start indoors under lights. Hopefully, I will end up with many plants to share, as I have gotten many requests for some. Many thanks.

My Canna Lilies still have stalks, they are mixed brown and green and starting to wilt. Do I wait for them to go in the ground before digging up the bulbs?
Do I dig them up today and cut off the stalks?
