Once established, cannas need to be kept moist. They also require monthly fertilizer that is relatively higher in phosphate for continual bloom. It's usually necessary to dig up and store canna rhizomes in the fall. They can also be overwintered in pots and allowed to grow throughout the winter season. In spring they can be replanted or moved back outdoors. You can also divide the plant during this time if necessary.
- Light Needs: Full sun
