When is the latest blooming season for canna lilies? A detailed explanation of blooming time
Canna lilies have large, brightly colored flowers and rich colors, good plant shape, are easy to cultivate, and have high ornamental value. They can be grown in pots or in the ground. Many people like to grow them in their courtyards. They have the effect of purifying the air and protecting the environment, and are ideal flowers for greening, beautifying and purifying the environment. Now let us take a look at when the blooming season of canna lilies is!
When do canna lilies bloom
Canna lilies are perennial bulbous herbaceous flowers. Flower colors include creamy white, bright yellow, orange-yellow, tangerine, pink, bright red, purple-red, multi-colored spots and more than 50 varieties. In the north, the blooming season is usually from June to October, while in the south they bloom all year round.
How to extend the blooming season of canna lilies
1. Move them indoors in time: Canna lilies are subtropical flowers and like a warm climate and abundant sunlight. At a temperature of 25°C-28°C, they bloom quickly, and it usually takes about 7 days from bud appearance to flower viewing. In the north, if you want canna lilies to bloom in winter, they must be moved indoors before October 15.
2. Keep them warm indoors: Keep the indoor temperature at 15°C-18°C, and the blooming season can be extended to New Year.
3. Ensure sufficient sunlight: After moving indoors, the daily sunlight time should not be less than 4 hours. If sunlight is insufficient, you can use a 60-watt light bulb or a 40-watt fluorescent lamp for lighting to supplement light. With 4-6 hours of sunlight per day, you can ensure bright flowers and tender leaves.
4. Fertilizer and water should be appropriate: After moving canna lilies indoors, the soil moisture content must be kept at 40%-50%. Water with dilute liquid fertilizer once every half month, add soybean cake water, livestock hoof water, or apply a 500-fold potassium dihydrogen phosphate solution. However, water and fertilizer should not be excessive; water frequently and lightly to prevent root rot.
How to grow canna lilies
1. Soil: They are not strict about soil requirements. They grow best in loose, fertile, well-drained sandy soil, and also adapt to fertile clayey soil.
2. Sunlight: During the growing period, sufficient light is required, ensuring at least 5 hours of direct sunlight every day. If the environment is too dark and light is insufficient, the blooming period will be delayed
3. Temperature: They like warmth and fear severe cold. The suitable growing temperature is 16-30°C. Growth will stop at 5-10°C, and cold damage will occur below 0°C. When blooming, to extend the blooming season, they can be placed in a low-temperature place without sunlight, and the ambient temperature should not be lower than 10°C.
4. Watering: After planting, before the rhizomes have grown new roots, water less. Keep the potting soil moist. Soil that is too wet easily causes root rot. After the flower stalk grows, water frequently to keep the potting soil moist. If water is lacking, the phenomenon of “flowers hidden among leaves” is likely to appear after blooming. In winter, watering should be reduced, following the principle of “dry and wet alternately”.
5. Fertilizing: In addition to applying sufficient base fertilizer before planting, during the peak growing season, apply thin cake liquid fertilizer 3-4 times a month. If the flower stalk has not yet emerged 20-30 days before the scheduled blooming period, spray the leaves once with a 0.2% potassium dihydrogen phosphate aqueous solution to promote flowering.
6. Pests: Canna lilies are highly adaptable and relatively easy to manage. They are not delicate, and pests are also few. From May to August every year, pay attention to leaf-roller pests to avoid damaging their tender leaves and flower spikes. You can spray with 50% dichlorvos 800-fold solution or 50% fenitrothion emulsifiable concentrate 1000-fold solution for control.
