How to Plant Canna Durbans

Overview

Canna durban is a tall variety of canna lily plants and a member of the Cannaceae family that consists of 55 species. Canna durban is a flourishing tropical perennial grown from rhizomes that produces large prominent leaves and bright red blossoms from summer until frost. Growing to heights over 5 feet with spreads near 2 feet, canna durban grows best in USDA hardiness zones 8 to 11. Plant canna durban rhizomes after the chance of frost has passed.

Step 1

Plant the canna durbans in locations providing moist soil and full sun to partial shade. Allow enough room to space the rhizomes 18 inches apart.

Step 2

Cultivate the planting area to a depth of 12 inches. Mix in a 2- to 4-inch layer of compost to enrich the soil.

Step 3

Dig a hole with a hand trowel 4 to 6 inches deep. Place a canna durban rhizome in the hole horizontally.

Step 4

Cover the planted rhizomes with soil and saturate with water. Continue to supply 1 inch of water weekly to the cannas throughout the growing season, if rainfall is less.

Step 5

Add a 2- to 4-inch layer of mulch around the planted canna durbans to deter weeds and preserve moisture.

Step 6

Apply a balanced fertilizer as directed on a monthly schedule through the summer season.
