Plant rhizomes 12 to 18 inches apart, covering with two to three inches of
soil. Place the long part of the rhizome horizontally in the ground with the
eye up, if visible. Canna rhizomes do not have a top or bottom, so no worry
of placing it upside down. In colder regions, cannas may be planted in pots
and placed in greenhouse conditions six to eight weeks prior to planting.
When all danger of frost is past, remove from pots and plant outside.

Cannas should be watered thoroughly once a week by slowly soaking the area
around the roots. For optimum performance, add a general all purpose
fertilizer (10-20-10 is fine) at planting time and once during the growing
season. Cannas are not high users of nitrogen. It is not necessary to dead
head the spent flowers and seed pods to induce new blooms, however, your
flower bed will appear more striking without the old blooms.
