I am in TX and do not need to dig up my canna bulbs for winter...when and how far back should I cut the leaves and stalks?

I would cut the spent Canna canes down to the ground. Then allow the other canes to flower.
Cannas do need to be lifted and divided once a year and spring is the best time to do this.
Before lifting the plants, cut them down to about 5 to 6 inches high.
