Canna Glauca Care

In the spring, after the last frost, plant the rhizome 4 to 6 inches deep. If the plant has been grown in a container, you can submerge the container in ponds or water gardens with the crowns under no more than 8” of water.

Cannas grow on rhizomes, and like most rhizomes plants, they need to be cut down to the ground once the plant is done actively growing. The best time to do this is a few days after the first hard frost of fall. The frost kills the aboveground parts of the plant. Let them dry out, and then prune them.

Cannas are not picky when it comes to fertilizer. Cannas easily bloom all summer without much effort. But for those of you who want to give your plants an extra boost, apply a 5-10-5 or 10-10-10 in the spring and, if you wish, two more times during the growing season.

Full sun (6 or more hours of direct sunlight a day)

Heavy (clay) soils and prefers well​-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils.

Lift the containers in fall, cut back the plant tops and overwinter the containers in cool, dry, frost-free locations until spring.
