When is the florescence of banana?

Canna has large and colorful flowers, rich colors, good plant shape, easy cultivation and high ornamental value. It can be potted or planted on the ground. Many people like to keep them in the courtyard, which can purify the air and protect the environment. They are ideal flowers for greening, beautifying and purifying the environment. Let's take a look at the florescence of canna.

When does the canna blossom

Canna is a perennial bulbous herbaceous flower with more than 50 varieties such as milky white, bright yellow, orange, orange, pink, bright red, purple and complex spots. The florescence is usually from June to October in the north and blossoms throughout the year in the south.

How to prolong the flowering period of Banana

1. Enter the house in time: canna is a subtropical flower, which likes warm climate and plenty of sunshine. When the temperature is 25 ℃-28 ℃, the flower blossoms quickly, and it can go from budding to flower appreciation in about 7 days. In the north, if the canna is to bloom in winter, it must be moved indoors before October 15.

2, indoor heat preservation: the indoor temperature should be kept at 15 ℃-18 ℃, and the florescence can be extended to the New year.

3. Sunshine should be sufficient: after entering the room, the sunshine time should not be less than 4 hours a day. If the sunshine is not enough, you can use 60 watt light bulb or 40 watt fluorescent lamp to supplement lighting. Sunshine for 6 hours a day ensures beautiful flowers and tender leaves.

4. Fertilizer and water should be suitable: after the canna is moved indoors, the soil water content must be kept at 40% 50%. Pour dilute liquid fertilizer once a month, add bean cake water, livestock hoof water, or 500 times potassium dihydrogen phosphate solution. However, water and fertilizer should not be too large, and should be watered frequently and less to prevent rotting roots.

Culture methods of canna

1. Soil: the requirement of soil is not strict, it grows best in loose, fertile and well-drained sandy soil, and it is also suitable for the growth of fertile clayey soil.

2. Sunshine: sufficient sunlight is required during the growing period, and be sure to receive at least 5 hours of direct sunlight every day. If the environment is too dark and there is not enough light, the flowering will be delayed.

3. Temperature: like warmth, avoid severe cold, the suitable temperature is 16-30 ℃, 5-10 ℃ will stop growing, and freezing injury will occur when it is lower than 0 ℃. When flowering, in order to prolong the flowering period, it can be placed in a place with low temperature and no sunlight, and the ambient temperature should not be lower than 10 ℃.

4. Watering: after planting, the rhizome should be watered less before it grows new roots. The basin soil should be moist. The soil is too wet and rots easily. After the scape grows, it should be often watered to keep the basin soil moist. If there is a lack of water, it is easy to appear the phenomenon of "flowers in the leaves" after flowering. Watering should be reduced in winter, based on the principle of "dry and wet".

5. Fertilization: in addition to applying sufficient base fertilizer before planting, thin cake liquid fertilizer should be applied 3-4 times a month in the peak growing season. If the scape is not produced 20-30 days before the scheduled flowering period, 0.2% potassium dihydrogen phosphate aqueous solution can be sprayed once to promote the flowering.

6. Insect pests: canna has strong adaptability, extensive management, not spoiled, and few insect pests. Attention should be paid to leaf curling pests from May to August every year so as not to damage their tender leaves and inflorescences. It can be sprayed with 50% dichlorvos 800 times or 50% prednisone EC 1000 times.
