I grow almost all of my cannas in big pots, and yes you can cut back any of them. They are so vigorous, they will send up plenty more. I did just that last summer when the jap beetles at the hell out of the leaves. I would select the worst ones and as they fill in continue to cut out the bad ones. check out my canna photos too!
