Last year my cannas were doing fine in the beginning, however, the leaves started turning brown and crusty and were not opening properly. When I peeled one open, at the base of the leaf there was a moist clump of something similar to mud. Could this havebeen caused by grasshoppers?

Sounds as though your Cannas have developed a fungal disease known as Southern Blight (Sclerotium rolfsii). To stop the spread, rogue out and destroy the affected plants. If you want to grow Cannas again, plant new ones in a different location in the garden. Cannas grow best in loose soil with good drainage. Remove faded flowers after bloom and after all flower clusters have bloomed, cut the stalks to the ground.
