Legume green requires soil humus to be rich, loose, fertile and well drained. 7 parts of leaf soil and 3 parts of river sand can be selected, and a small amount of base fertilizer can be added to prepare culture soil, or 6 parts of peat soil, 4 parts of perlite and a small amount of base fertilizer can be mixed to prepare. When planting, we usually buy potted plants directly, and do not need soil, so we can understand the composition of soil a little.
The green color of bean petals likes warm, humid and semi overcast environment. It is resistant to high temperature. The suitable temperature for growth is about 25 ℃. It can grow normally at 10-15 ℃ in winter, stop growing below 10 ℃, suffer from damage below 5 ℃, and freeze and die below 0 ℃. A small pot of green bean petals is not so easy to raise.
Douban green is more shade resistant. It can be cultured indoors in all seasons with bright scattered light. More light can be seen in spring and autumn, sunshine can be seen near the south window edge in winter, and the North window sill in summer, with proper shading. When the light is suitable, the leaf color is gorgeous. If the light is too strong or too dark, the leaf color will lose its delicate color.
It is suitable to water basin soil dry and wet. In the growth process, spring and autumn is the peak season of growth and development, with more water. It is hot in summer, but the plant grows slowly because of the high temperature. It can be watered once in the morning or once in the evening. The high temperature and wet leaves are easy to rot, depending on the weather and pot soil. The basin soil should be slightly dry, because its stem and leaf are fleshy and thick, and it is easy to rot the root when it is too wet. Especially in winter, because of the low temperature, it is in a dormant state, so the basin soil should be dried.
The cultivated soil is usually renewed once every 2-3 years. During the growing period, liquid fertilizer or nitrogen and phosphorus fertilizer were applied every 15-20 days, the concentration of which was cake fertilizer 15% - 20%, nitrogen and phosphorus compound fertilizer 0.2% - 0.3%. If the fertilizer is not properly applied, the nitrogen fertilizer can be reduced, and the mottling on the leaves can be more significant.
Don't look at the small bowl of Douban green. It's very lovely. It's well raised by others. If you care twice, it will be in vain. So trim it in time. When the green of the bean petal grows to about 10 cm, the heart should be removed to promote the germination of the lateral branches and make the plant fuller.
Usually, the management should pay attention to appropriate light and reasonable water. When the sun is not too strong, the potted plants can be placed outdoors. But in summer, it can't be directly exposed to strong light, especially in the sun, otherwise it will cause yellow branches and leaves.
