Canna varieties, such as, for example, “Lucifer” (60 cm/2 feet high), “Suevia” (90 cm/2.9 feet), “Hungary”, “Pfitzer”, “Chinesecoral” (70-90 cm/2.3-2.9 feet) can be used for planting in containers on balconies, in the design of outdoor terraces, where they will contribute to the creation of an unusual southern flavor.
Canna is convenient to store in large containers in the garden in summer, in winter in a cool but frost-free room. At the same time, you can get flowering in June, and then again in December in the winter garden.
The germination of rhizomes begins in February, otherwise the canna will bloom only in the fall, and in the cool summer it may not bloom at all. Part of the rhizome with 1-2 buds and roots is planted in a box with raw sand to a depth of 5 cm (2 inches), covered with glass and put in a warm place (+18-+20°/64.4-68°F). When you see the sprouts, remove the glass and spray the seedlings every day. In March, when the third leaf begins to develop, each plant is planted in a pot with a diameter of 22 cm (8.6 inches) with humus soil, transferred to a bright, cool place. In the first half of May, the plants are transplanted into containers measuring 30x30x40 cm (1x1x1.3 feet), in a substrate of equal parts of leaf, turf, humus, peat and sand. When the threat of frost passes, the container is buried in the garden.
Canna will bloom in June and will delight you until the coldest weather. In the second half of September, they need to be transplanted again into larger containers of 50x50x60 cm (1.6×1.6×2 feet) and transferred to the winter garden. There they will bloom in December.
In winter, you can not water the canna, as this can lead to root rot. In February-March, after flowering, the plants are cut off, removed from the container and, without clearing the ground, dried for a week. Then divide and put on germination. Before planting, it is good to hold the rhizome for about a day in a 0.1% solution of potassium permanganate.
