The latest culture methods of blue beans

Blue bean is a rare perennial herb of crassulaceae, and it is also a rare fragrant succulent plant, native to northeastern Mexico, with light blue leaves and oblong leaves. The leaf color will become very beautiful blue and white during the strong light and the temperature difference between day and night or during the low temperature period in winter. Let's take a look at the cultivation methods of blue beans.

Growth habits of Blue Bean

Blue beans like a warm, dry and sunny environment, resistant to drought and avoid dampness. If placed in the shade for a long time, the plant shape is loose, the leaves are sparse, and it is difficult to blossom. Usually watering should not be too much, so as not to cause plant rot caused by too wet soil. Pay attention to good ventilation at high temperatures in summer.

Propagation methods of Blue Bean

The reproduction of blue beans can be combined with changing pots for split plants, and the strong and full fleshy leaves can also be cut flat in the sandy soil during the growing season, keeping the basin soil slightly moist after cutting, and many new buds will grow at the wound at the base. When these new buds are slightly larger, take them and plant them alone to become new plants.

Culture method of Blue Bean

1. Soil: blue beans like sandy loam rich in humus and can adapt to barren soil. The basin soil should be made of loose and fertile sandy soil with good air permeability, which can be mixed with 3 parts of rotten leaf soil, 3 parts of river sand, 1 part of garden soil and 1 part of slag, and mixed with a small amount of calcareous materials such as bone powder.

2. Watering: blue bean watering should master the principle of "no dry, no watering, watering thoroughly" to avoid stagnant water in the basin soil, otherwise rotting roots will occur. Water can be sprinkled around the plant when the air is dry, but the leaf surface, especially in the center of the leaf clump, should not accumulate water, otherwise it will cause a rotten heart, especially to avoid long-term rain.

3. Sunshine: blue beans are resistant to high temperature and hot sun, but the leaves with too strong light are easy to aging, which affects the ornamental effect, so when the temperature is hot, they should be arranged on the balcony or windowsill with light in the morning and evening. The leaf color of blue bean will become very beautiful blue and white in the strong light and the temperature difference between day and night or during the low temperature period in winter.

4. Temperature: blue beans are placed 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 maintain such a high temperature, we should control watering, keep the basin soil dry, stop fertilization, make the plant dormant, and be able to withstand the low temperature of 5 ℃.

5. Fertilization: mature thin liquid fertilizer or compound fertilizer with low nitrogen and high phosphorus and potassium is applied every 20 days or so in the growing season of blue beans, but it is OK not to apply fertilizer. Do not splash fertilizer and water on the leaves when applying fertilizer. 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.

6. Insect pests: blue beans are often harmed by rust, leaf spot and root-knot nematodes, which can be sprayed with 75% chlorothalonil wettable powder 800 times and root-knot nematodes with 3% carbofuran granules. Pests are harmful to black weevil and are sprayed with a 500-fold solution of 25% carbaryl wettable powder.
