Culture method of Blue Bean

Blue bean is a rare perennial herb of the family Crassulaceae. It is also a rare fragrant succulent plant. It originates in northeastern Mexico. The leaf color of the plant is light blue. The leaf color is oblong. The leaf color will change very beautiful blue and white in strong light and temperature difference between day and night. Let's take a look at the breeding method of blue bean together.

The growth habits of blue beans

Blue beans like warm, dry and sunny environment, drought resistance, avoid water wet. Long-term placed in the shade, the plant shape is loose, the leaves are sparse, and it is difficult to flower. Usually watering should not be too much, so as not to cause the soil too wet plant rot. Pay attention to good ventilation in high temperature in summer.

Blue bean propagation method

The propagation of blue beans can be combined with pot change for plant division, or in the growing season, the robust and full fleshy leaves can be placed flat in the sand for cuttage, after insertion, keep the pot soil slightly moist, the wound at the base will grow a lot of new buds, and when these new buds are slightly larger, they will be taken down and planted separately to become new plants.

Culture method of blue bean

1. Soil: Blue beans like sandy loam rich in humus and can also adapt to poor soil. Basin soil should be loose fertile, sandy soil with good permeability, available 3 parts of rotten leaf soil, 3 parts of river sand, 1 part of garden soil, 1 part of slag mixed preparation, and mixed with a small amount of bone powder and other calcareous materials.

2, watering: blue beans watering master the principle of "do not water, water is poured through", avoid pot soil water, otherwise it will occur rotten roots. When the air is dry, sprinkle water around the plant, but the leaf surface, especially the center of the leaf cluster, should not accumulate water, otherwise it will cause rotten heart, especially to avoid long-term rain.

3. Sunshine: Blue beans are resistant to high temperature and scorching sun, but the leaves are easy to age when the light is too strong, which affects the viewing effect. Therefore, when the temperature is hot, they should be arranged on the balcony or windowsill with light in the morning and evening. Blue bean leaf color in strong light and temperature difference between day and night or winter low temperature period leaf color will change to a very beautiful blue white.

4, temperature: blue beans in winter indoor sunny place, if the lowest temperature at night in 10℃, and there is a certain temperature difference between day and night, can be properly watered, appropriate fertilization, so that plants continue to grow. If you can't keep such a high temperature, you should control watering, keep the pot soil dry, stop fertilizing, make the plant dormant, and also withstand a low temperature of 5℃.

5. Fertilization: apply decomposed thin liquid fertilizer or compound fertilizer with low nitrogen and high phosphorus and potassium every 20 days or so in the growing season of blue beans, but do not apply fertilizer. Do not splash fertilizer water on the leaves when applying fertilizer. Fertilization is generally carried out in the morning or evening of sunny weather, and the evening of the same day or the morning of the next day is watered once to dilute the residual fertilizer in the soil.

6. Pests: Blue beans are often damaged by rust, leaf spot and root-knot nematode, which can be controlled by spraying 800 times solution of 75% chlorothalonil wettable powder, and root-knot nematode can be controlled by 3% carbofuran granules. Black weevil pest damage, with 25% carbaryl WP 500 times spray kill.
