Care Guide

Cannas are relatively easy to care for and can be grown in a variety of conditions. Here are some tips for keeping your cannas healthy:- Water: Cannas prefer moist, well-drained soil. Water regularly, especially during hot and dry weather.- Fertilization: Cannas benefit from regular fertilization with a balanced fertilizer. Apply every 2-3 weeks during the growing season.- Soil: Cannas prefer rich, fertile soil that is slightly acidic. Add compost or other organic matter to improve soil quality.- Sunlight: Cannas prefer full sun to partial shade. They can tolerate some shade, but they may not flower as well.- Hardiness Zones: Cannas are hardy in zones 7-10. In colder climates, they can be grown as annuals or dug up and stored for the winter.
