Do canna lilies need sun or shade?
Light: Cannas need full sun to reach their flowering potential. Shade encourages leggy growth that can cause foliage to flop over. Plants in shade won’t produce as many flowers, either. Several varieties are grown for their colorful leaves, which are not as bright in the shade. Cannas need full sun for good flowering and consistently moist soil with a pH of around 6. Add lime before planting if your garden soil is acidic (low pH).Cannas planted in zones 8 and warmer can be left in the ground all winter. Zone 7 is middle ground for determining what to do with cannas in the winter. Digging cannas in the late fall is necessary to overwinter cannas in zones 6 and colder.In the fall, dig rhizomes after the leaves have yellowed, died back or have been killed by frost, but before the ground freezes. Leaving your cannas till after a freeze provides the longest possible growing season so the plant can store food for next year’s growth. Cut back dead foliage to 2 inches.Cannas are hardy to Zone 7 (0°F). In colder climates, they can be overwintered indoors. After the first frost in fall, cut the stems to the ground and lift the clump of rhizomes with a spade or fork. Store in a dry, well-ventilated place where the temperature is cool (50°-60°F).
Do canna lilies grow better in pots or in the ground?
The best time to plant canna lilies is in April and May, and are usually best started off in pots. Cannas have strong underground stems, known as rhizomes. In the dormant season you’ll find rhizomes for sale in bags in the garden centre or nursery. In summer they’re sold as potted plants. Often used in bedding displays, tropical borders or large containers, canna lilies are great value for money, giving years of colour and drama. They flower from June to October.For a stunning container display, plant 1-2 canna lilies per container to allow enough space for their roots to spread.Canna lily (Canna X generalis) is an herbaceous perennial. This means that Cannas will die back over winter and regrow from the root in spring.Canna lilies should be watered once or twice a week depending on temperatures. This could be less if your soil retains moisture well or receives adequate rainfall.
Do canna lilies multiply?
How: Plant the rhizomes horizontally 2-4 inches deep, with any visible buds facing upwards. Canna Lilies multiply quickly, and therefore spacing is usually recommended at 12-18”. However, if you want a fuller look and your soil is rich, spacing them 8-12” will not harm the plants. Bryan Clayton, CEO of GreenPal adds: ‘In my experience, the best time to prune canna lilies is in the late fall or early winter, after the first frost. Frost typically signals the plant to go dormant, which is when you want to start your pruning.Canna Lilies: A Bit of Botany For Gardeners Cannas growing in suitable, in-ground conditions will spread via this rhizome, sometimes aggressively. Plants also produce seed, but it is much more common to acquire them as divisions of rhizomes.Canna lilies typically bloom from June to October. In planting zones 8 and up, cannas will repeat-bloom throughout summer, and throughout the year in zones 9 and above.The Bottom Line.
