Canna lily

Question

Canna lily leaves are curling up.

Answer 1

Would it be possible for you to post a picture? Leaf curling could be caused by watering problems, so make sure you are watering evenly so that the plants do not dry out.

Also check inside the curled up leaves for any insects that may be munching inside. However, this would be rare with canna lilies.
