Happiness tree is bean tree, it likes high temperature and humidity, sunshine foot environment, can be seen in many families or some office places, growing very lush, also known as evergreen. So, do you know how happiness tree should be potted indoors? The following is the method of learning about potted happiness tree!
1. Maintenance environment
Bean trees like high temperature and humidity, sufficient sunshine environment; they are resistant to high temperature, cold and cold, should be wet, avoid dry, and grow in the valley or plain forest.
The cultivation of bean tree should be loose and fertile, well drained, rich in organic matter loam and sandy loam.
2. How can happiness tree grow well?
Bean trees like warm and hot environment, and the suitable temperature for growth is 20 ℃ to 30 ℃. In midsummer and hot summer, when the ambient temperature is above 30 ℃, it is necessary to build a shed for shading, increase the environment and foliar spray water, or move it to a cool and ventilated place with sparse shade for summer. At the end of autumn, when the ambient temperature drops to about 10 ℃, it should be moved to the shed in time.
During the winter, it is better to maintain a shed temperature of no less than 8 ℃ and at least not lower than 5 ℃.
Family potted plants can be moved to the room with air conditioning or electric heater to ensure that the room temperature is not lower than 8 ℃, so that it can survive the winter safely.
Bean tree is a light loving plant, but also slightly shade tolerant, full sunlight, half shade environment can be. The seedlings are shade tolerant and need to be shaded in summer.
Cultivation of Bean Trees requires a relatively humid soil and display environment. During the dry season, we should pay more attention to the moisture supply in the seedling bed. Potted bean trees, in order to make it not too tall, in spring sprouting new shoots, can be properly controlled watering, to maintain the basin soil more humid.
Potted bean trees should be cultivated in loose and fertile soil with good drainage and air permeability and rich in organic matter. It is usually prepared by mixing 5 parts of garden soil, 3 parts of rotten leaf soil, 1 part of decomposed organic fertilizer and 1 part of river sand. In the growing season, the soil should be loosened once a month to ensure that its roots are always in a good state of permeability.
In addition to adding proper amount of rotten cake fertilizer and 3% compound fertilizer to the culture soil, top dressing should also be applied continuously. In the growing season, the quick acting liquid fertilizer can be poured once a month, usually the rotten cake fertilizer water can be used.
3. Disease control of bean tree
1. Leaf spot disease
In the environment of high temperature, high humidity and poor ventilation, its leaves are susceptible to leaf spot disease.
Whether indoor or outdoor, ventilation and light transmission should be strengthened to avoid long-term stagnant water on the leaf surface and reduce the possibility of leaf spot disease. If a small amount of diseased leaves were found, they should be removed and burned in time. Spray 600 times 50% carbendazim WP regularly, once every half a month, three to four times in a row.
2. Scale insects
Under the conditions of high temperature, high humidity and poor ventilation, especially in autumn and winter, when it is placed in the greenhouse for a long time, its stem and leaves are easy to be damaged by scale insects.
If a small amount of live insect body is found, it can also be glued off with transparent tape. The nymphs were sprayed with 25% chlorpyrifos at the peak of hatching.
4. What reason is the leaf turns yellow, how to solve?
1. Water yellow
The long-term wetting of basin soil results in soil anoxia, which weakens the ability of root system to rot, absorb water and fertilizer. The young leaves are dark yellow and lusterless, the apex of new shoots is atrophied, and the branches and stems are small yellow green.
The soil should be loosened, watering should be controlled, fertilization should be stopped, the heavy can be removed from the basin, and the soil ball should be dried at the shade before the basin is put on.
2. Fat yellow
The yellow leaves caused by excessive fertilization or concentration, especially partial application of nitrogen fertilizer, showed that the new leaves were thick and glossy, but the concave convex surface of the leaves was not extended, and the old leaves gradually turned yellow and fell off.
Stop fertilization and increase the amount of water properly to dilute nutrients, potted flowers lack of fertilizer and water or plant big pot small, pot root senescence or too dense.
3. Alkali yellow
It is shown that the veins, especially the main veins, are still green, and the phenomenon of yellow green alternation is very obvious.
With the aggravation of yellowing degree, the veins of leaves gradually lose their green, and then the whole leaves turn white, the leaf edge is scorched, and the leaves wither. In serious cases, the top of branches and even the whole plant are dead. For this "yellowing" phenomenon, acid fertilizer or acid substance can be applied to improve it, or alum fertilizer water can be often applied.
4. Yin Huang
Flowers like sunshine, often due to insufficient indoor light, resulting in withered leaves, at this time should be moved to outdoor pot ventilation lighting. For semi negative flowers, such as asparagus, leaves will turn yellow under strong light, so to avoid exposure to high temperature and strong light in summer, they should be moved indoors or stored in a shade shed.
Due to long-term no watering or less watering, the leaves turn yellow or brown end and brown edge, and the old leaves wither and fall off from bottom to top. However, the new leaves generally grow normally. When this phenomenon occurs, water should be added to make the soil no longer lack of water.
