Growing Instructions
Plant Cannas in the spring after all danger of frost has passed. Cannas prefer full sun to partially shaded locations - full sun for cooler areas. The ideal soil is rich and porous and drains well, yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed and incorporate into the soil to a depth of 10 inches. Plant rhizomes 3-5" deep and 4-6" apart. Cover with soil. When planting a large number of Cannas in one bed, excavate the entire area to the recommended depth, work fertilizer into the bottom of the trench, set out rhizomes and then cover all at once. Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach roots. Mulch to keep the soil cool and to prevent the soil from drying out. Apply fertilizer during growing season until foliage starts to turn yellow. After frost has damaged the foliage, dig up clumps, trim foliage, shake off soil and divide into 3-5 eye rhizomes. Place clumps in a plastic bag with peat moss to maintain a nice moisture balance. Add air holes to the sides of the bag to allow a small amount of air flow during storage. Store in a cool, dark place at 45-55ºF during the winter. Be sure to check on them a few times to make sure they are not too moist or too dry. Replant in spring after all danger of frost has passed.
Care Tip
Plant cannas in large containers to add easy, tropical color to your patios and decks. Cannas can be planted after all danger of frost has past but they prefer soil temperatures of at least 65ºF.
