You’re in luck. In warm climates (USDA hardiness zones 8 to 10), canna lilies can simply be left outside in the ground. If you live in a colder climate, you can lose them so dig up the roots and throw them in a pot to put in the garage.
In terms of pruning, you really don’t have to do anything if the foliage looks good. If the leaves look trashy, you can trim out the dead foliage and giving it room to grow new foliage. At the end of the season, in cooler climates, you may see that the cannas die back as the nights get colder. You can chop them down to the ground and they’ll come back again next year.
If you have canna in pots, you can clean them up throughout the season. Sometimes if it gets really hot, the leaves can get sunburnt. You don’t ever want to cut the main stem. Just trim off the brown leaves at the bottom near the stem. You can also just trim the tops of leaves if they’re brown (like a haircut).
