The reasons for the drooping leaves of Avalokitella mandshurica

Sedum family Guanyinlian, also known as Buddha pedestal lotus, is a succulent plant of crassulaceae family. It likes sunny and cool environment. Many flower lovers always encounter drooping leaves in the process of breeding. Most of the problems are one or several of the following. Let's take a look at the reasons for the sagging leaves of crassulaceae.

Growth habits of Guanyinlian of crassulaceae

Crassulaceae Guanyinlian is an alpine succulent plant, which likes sufficient sunshine, cool and dry environment, and is suitable for all kinds of acidic, neutral and alkaline soil. except for proper shading and avoiding hot sun exposure in summer, it should be fully sunny in other seasons, controlled watering in winter, low temperature of-20 ℃, dormancy in summer high temperature and cold in winter, and cooler spring and autumn seasons are its main growing period. Sufficient sunlight is required, if the lack of light will lead to loose plant type, not compact, affecting its appearance and ornamental, while the plants growing in sufficient light, the leaves are thick and full, the plant type is compact, the leaf color is beautiful, and looks very beautiful.

The reasons for the drooping leaves of Avalokitella mandshurica

1. With high humidity and low temperature, the tuber is very perishable or has rotted.

2. If the indoor temperature is lower than 15 ℃, the growth of Guanyinlian is stagnant and dormant, and the aboveground leaves begin to wither gradually, so the amount of watering should be reduced as much as possible.

3, too much watering, resulting in stagnant water, the root system can not breathe, resulting in leaf sagging or even death; it is best to spray, while ensuring humidity, but also does not make the basin stagnant water.

4. Lack of light will lead to loose and drooping plant shape, not compact, while plants growing in sufficient light have thick and plump leaves, compact plant shape and beautiful leaf color.

5, or due to transplanting caused by poor root growth, unable to absorb water, and so on.

The Culture method of Guanyinlian in Sedum Family

1. Soil: the basin soil is required to be loose and fertile and has good drainage and permeability. Half of rotten leaf soil or peat soil, coarse sand or vermiculite can be used, and a small amount of bone powder and other calcareous materials can be mixed and used. Because the soil is moist, the newly planted plants do not need to irrigate too much water to maintain their semi-dry state to facilitate the restoration of roots.

2. Temperature: the growth environment is warm, humid and semi-overcast, the suitable growth temperature is 20-30 ℃, and the overwintering temperature is 15 ℃. In winter, when the temperature is not lower than 5 ℃ at night and above 15 ℃ during the day, the plant can continue to grow and can be watered normally and fertilized properly, and if watering is controlled to make the plant dormant, it can also tolerate the low temperature of 0 ℃. The long-growing grass is not heat-resistant, and the plant growth stops gradually after May. When it enters the summer dormancy period, the family can keep it under the corridor or on the inside of the balcony where there is no direct sunlight, good ventilation and no rain, and control watering and stop fertilizing, so as to avoid plant rot caused by muggy, damp and stagnant soil.

3. Illumination: plants are dormant in high temperature in summer and cold in winter, and the main growth period is in the cooler spring and autumn seasons. Sufficient sunlight is required in the growth period. If insufficient light will lead to loose plant shape, not compact, affecting its ornamental, while the plants growing in the place of sufficient light, the leaves are thick and plump, compact and beautiful.

4, watering: watering master "do not dry, watering thoroughly", avoid long-term stagnant water, so as not to cause rotten roots, but not too dry, otherwise the plant will not die, but the growth is slow, the leaf color is dim, and there is a lack of vitality. In the period of high temperature in summer, the leaf water evaporation is large and the water demand is more, such as the lack of water is very easy to make the leaf wilt, so it is necessary to spray water to the leaf surface frequently and keep the environment moist at the same time, but the stagnant water in the basin must be avoided, otherwise it will cause root rot.

5. Fertilization: apply mature thin liquid fertilizer or compound fertilizer with low nitrogen and high phosphorus and potassium every 20 days or so. Don't splash fertilizer and water on the leaves when fertilizing. Fertilization is usually carried out in the morning or evening when the weather is clear, and the water is watered once in the evening or the next morning to dilute the residual fertilizer in the soil. Put it in a sunny place indoors in winter, if the lowest temperature at night is about 10 ℃, and there is a certain temperature difference between day and night, it can be properly watered and fertilized as appropriate to make the plant continue to grow. If it can not keep such a high temperature, we should control watering, keep the basin soil dry, stop fertilization, make the plant dormant, and can withstand the low temperature of 5 ℃, and some varieties can even withstand the low temperature of 0 ℃.

6. Reproduction: the propagation of long-growing grass can cut the small buds (small rosette-shaped leaf disk) germinated at the base in the growing season, cut them in the sandy soil, keep a little damp after cutting, and take root in 2-3 weeks, and some of them have roots under the leaflet disk, which can be put on the basin directly. Leaf cuttings, although occasionally can survive, but the success rate is very low, so it is rarely used. If the seeds can be collected, they can also be propagated by sowing method. Under the condition of about 20 ℃, they can germinate in 10 to 15 days. Although the seedlings grow slowly, they can get a large number of seedlings at one time.

7. Change the basin: turn the basin every 1 to 2 years in spring or autumn, trim the root system when turning the basin, cut off the withered root or overlong old root, the basin soil is required to be loose and fertile, and have good drainage and air permeability. half of rotten leaf soil or peat soil, coarse sand or vermiculite can be used, mixed with a small amount of bone powder and other calcareous materials. Because the soil is moist, the newly planted plants do not need to irrigate too much water to maintain their semi-dry state to facilitate the restoration of roots.
