How to care for Canna Lily
Light. Grows best in full sun. It tolerates less sun if it is well cared for.
Water. Keep it well watered. Cannas grow in most soils as long as they get enough water and fertilizer.
Soil and feeding. Rich, organic soil is ideal. Feed with a balanced fertilizer such as Shrub Special monthly, or a controlled-release fertilizer less often.
Size. Grows to about 3 ft. Canna cultivars range from a few feet to over 15 ft.
Pruning. Remove spent flowers to keep new ones coming. If cold damages the plant, cut it back to 6–8 inches; it regrows when warm weather returns.
Problems to watch. The canna leaf roller can be a major pest, so check the leaves often.
Good to know. Divide crowded clumps after blooming or in mild weather. Replant each piece quickly, with good roots and leaves. 'Pretoria' is also sold as 'Bengal Tiger'.
