Planting Cannas in full sun produces the best foliage color and the number of blooms. Loosen the soil and place the rhizomes, horizontally with the eyes/growing points facing up, 4-6 deep and 2 apart for tall varieties, 1 apart for medium and dwarf varieties. Water thoroughly after planting. Keep soil moist but not soggy thereafter and fertilize once per month during the growing season. Feel free to cut the flowers, which does not hurt the plant. Most people grow Cannas for their lush, colorful foliage. Do not cut or remove the foliage. The plant needs the nutrients from the foliage for the next years growth. Remove leaves once they have died off
