Culture methods of longevity flowers

1. Soil selection for longevity flower culture:

Longevity flowers should not be cultivated in clayey soil, otherwise it will lead to poor growth, rotten roots and leaves, and in serious cases, plant death. The basin soil was mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone powder. This kind of cultivated soil is loose and fertile, has good drainage performance, and shows a slightly acidic reaction, which is beneficial to the development of root system.

2. Fertilization methods for longevity flower culture:

Longevity flowers should not be cultivated in clayey soil, otherwise it will lead to poor growth, rotten roots and leaves, and in serious cases, plant death. The basin soil was mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand, plus a small amount of bone powder. This kind of cultivated soil is loose and fertile, has good drainage performance, and shows a slightly acidic reaction, which is beneficial to the development of root system.

In the peak growing season, thin compound liquid fertilizer can be applied every 15 to 20 days to promote robust growth and luxuriant flowering. If 0.2% potassium dihydrogen phosphate or 0.5% superphosphate is applied twice after flower bud formation in November, the flowers will be more, the color will be bright, and the florescence will be long.

3. Watering methods for longevity flower culture:

Longevity flowers, like other succulent flowers, contain more water and have a strong ability to resist drought, so they do not need a lot of watering. During the growth period, as long as every 2-3 days to water once, keep the basin soil slightly moist. Watering should be controlled when the temperature is low in winter. If the watering is too much, the drainage is not smooth, and the basin soil is too wet, it is easy to cause root rot.

Although longevity flowers are more drought-tolerant, they can not be short of water in the growing season and can be watered every 2-3 days. In the stage of vegetative growth, the soil must be kept moist and watered at the right time. In summer, longevity flowers can be watered once a day in the environment of high temperature, strong sunshine, large evaporation and dry air. Cold winter, longevity flowers into the dormant period, it should be controlled watering, or even not watered for a short time.

Long-term cultivation of longevity flowers, if the long-term lack of light, not only slender branches, leaves thin and small, affecting the plant shape beautiful, but also reduce the number of flowers, flowers are not bright, but also cause a large number of leaves to fall off, the loss of ornamental value.

5. Temperature requirements for longevity flower culture:

The most suitable temperature for longevity flower growth is 20-25 ℃. More than 30 ℃ or less than 10 ℃, it obviously stopped growing and entered a dormant or semi-dormant state. In winter, if the temperature is lower than 10 ℃, move into the greenhouse to survive the winter. If there are conditions, the indoor temperature can be controlled at 16: 20 ℃ during the day and 10: 15 ℃ at night, so that longevity flowers can blossom on New year's Day and Spring Festival.

The room temperature in winter should not be lower than 12 ℃. It is better to use 15: 18 ℃ in daytime and more than 10 ℃ at night. If the temperature is as low as 6: 8 ℃, the leaves will turn red and the flowering period will be delayed.

The heart-picking method of longevity flower culture:

In the early stage of vigorous growth, we should pay attention to pick the heart in time, promote more branches, in order to facilitate the fullness of plant shape and improve the ornamental effect. Cut off the remaining flowers in time after the flower fade, so as not to consume nutrients and affect the number of flowers next time.

If you can not accept sufficient sunlight for a long time, the branches will become weak, the flowers will be dim and the flowers will wither, and the leaves will soften and fall off and affect the ornamental.

3. The ambient temperature should be maintained above 12 ℃. If the temperature is too low, the edge of the leaf will turn red and the flowering will be delayed.

4. Longevity flower is a kind of short-day flower, which can differentiate only when the temperature is 20 ℃ and the sunshine is 8 hours. After the flower bud is formed, according to the light demand of the plant blossom, let it receive scattered light before 10:00 and after 4pm every day in summer, avoid the strong sun at noon, and cover 40% of the light with a sunshade net. Try to keep it under fluorescent lamps at night, so that summer can continue to bloom. During the growing period, in addition to shading in the middle of summer, it is also necessary to maintain a light transmittance of 60%, and give sufficient light in other seasons.
