How to grow Canna lilies? Detailed guide to planting methods and care tips

Canna lilies are as elegant and beautiful as a beauty, with bright, large flowers and high ornamental value. Many people grow Canna lilies in their courtyards. Canna lilies are easy to cultivate and can be grown both in pots and in the open ground. Below, we introduce how to plant Canna lilies and the planting methods for Canna lilies.

I. Canna lily planting methods

Sunlight: Canna lilies require sufficient light during the growing period, ensuring at least 5 hours of direct sunlight every day. If the environment is too shady and light is insufficient, the flowering period of Canna lilies will be delayed.

Temperature: Canna lilies like warmth and are intolerant of severe cold. The suitable growing temperature is 16-30°C. Growth stops at 5-10°C, and cold damage occurs below 0°C. When Canna lilies are flowering, to prolong the flowering period, they can be placed in a low-temperature, sunless location, but the ambient temperature should not be lower than 10°C.

Watering: Before the rhizomes of Canna lilies have grown new roots, water less. The potting soil should be kept moist; overly wet soil easily causes root rot. After the flower scape emerges, water frequently to keep the potting soil moist. If water is lacking, Canna lilies are prone to the phenomenon of "flowers hidden among the leaves" after blooming. In winter, reduce watering, following the principle of "water when dry, stop when wet."

II. Canna lily care

1. Watering and fertilizing: After planting, before the rhizomes have grown new roots, water less. The potting soil should be kept moist; overly wet soil easily causes root rot. After the flower scape emerges, water frequently to keep the potting soil moist. If water is lacking, the phenomenon of "flowers hidden among the leaves" easily appears after flowering. In winter, reduce watering, following the principle of "water when dry, stop when wet." In addition to applying sufficient base fertilizer before planting, during the peak growing season, apply 3-4 times a month of thin cake liquid fertilizer as a top dressing. If the flower scape has not yet been produced 20-30 days before the scheduled flowering date, spray the leaves once with a 0.2% potassium dihydrogen phosphate aqueous solution to force flowering.

2. Flowering period control: If you want it to bloom for the "May First" holiday, in January cover the stored rhizomes with soil mixed with a small amount of fertilizer. The ambient temperature should be 30°C during the day and about 15°C at night. After 10 days, they will sprout. After sprouting, plant the rhizomes with 2-3 buds kept into pots, keep the potting soil moist, and apply fertilizer as appropriate. Flower buds appear in early April; pay attention to ventilation, and it can bloom by "May First."

3. Rhizome digging: In cold regions, after 1-2 frosts in autumn and when most of the stems and leaves have withered and yellowed, cut off the aboveground parts, dig out the rhizomes, dry them appropriately, and store them indoors in a pile. They can overwinter safely at a temperature of 5-7°C. In warm regions, they can overwinter in the open ground in winter and do not need to be harvested, but after 2-3 years they must be dug out and replanted, and the planting scale can also be expanded at the same time.

III. Uses of Canna lilies
