Money tree can purify the air, for indoor lampblack, the removal effect of odor is very obvious.

It is important to keep the money tree well and be familiar with its growth habits. Money tree is a perennial evergreen herb, belonging to the genus Amorphophallus of Araceae. It is an extremely rare foliage plant with underground tubers. It is native to the tropical (grass source) climate with less rainfall in eastern Africa. It is more resistant to drought, but is afraid of cold, avoid strong light exposure, and is afraid of heavy soil and stagnant water in the basin soil. If the basin soil is not permeable, it is easy to cause its tuber to rot. The soil is required to be loose and fertile, well drained, rich in organic matter and acidic to slightly acidic. The sprouting power is strong, after cutting off the thick compound leaves, the tip of the tuber will soon produce new leaves.

How to raise a potted cash tree? The method of cultivation and protection management of money tree is a question often asked by flower friends. Here is a brief summary of the cultivation methods of potted money tree. The specific maintenance and management methods are introduced as follows:

1. Soil

Because of the special climatic conditions of the original place of origin, it has formed a strong drought resistance, so the basic requirement for the cultivation substrate is good permeability. The basic requirement of cultivation substrate is good permeability. The cultivation medium was mainly mixed with peat, coarse sand or washed cinder and a small amount of garden soil, and its PH value was adjusted to between 6 and 6.5, showing a slightly acidic state. Because of its large tuber, developed root system and long pinnate compound leaves, its growth should be observed in time during the growing season to decide whether to change the basin or not. Always maintain the good permeability of the cultivation substrate, in order to create a good root environment with good air permeability and water filtration. Check frequently during the rainy season, and when it is found that there is stagnant water in the basin, turn the basin and change the soil in time.

2. Temperature

The suitable temperature for growth is 20-32 ℃, whether potted or planted on the ground, the average annual temperature change is small, and productive cultivation should be carried out in a greenhouse with controllable temperature. Every summer, when the temperature is more than 35 ℃, the growth of the plant is poor. Measures such as covering the black net to shade the light and spraying water to the surrounding environment should be taken to reduce the temperature so as to create a suitable environment with suitable space temperature and dryness. It is best to maintain the greenhouse temperature above 10 ℃ in winter. If the room temperature is lower than 5 ℃, it is easy to cause cold damage and seriously endanger the survival of the plant. In late autumn and early winter, when the temperature drops below 8 ℃, it should be transferred to the room with sufficient light, and the temperature should be kept between 8 ℃ and 10 ℃ during the whole overwintering period, which is more safe and reliable.

3. Lighting

The money tree likes light and has strong shade tolerance, so it should create a sunny but shaded environment to a certain extent. It avoids strong light, especially should avoid the hot sun exposure after long rain and early sunshine in late spring and early summer and the unsheltered strong light baking for 5-6 hours before and after noon in summer, otherwise it is very easy to cause burns of newly drawn young leaves. In productive cultivation, it should be placed under a shade of 50% to 70% shade from the end of spring to the Mid-Autumn Festival, but it should not be too dark, otherwise it will lead to slender leaves, yellow leaves and sparse leaflet spacing, thus affecting the compactness and beauty of the plant. Supplementary light should be given to potted plants transferred to the greenhouse in winter. If the water in the basin soil is kept dry, the plant can be kept disease-free for a long time. In addition, the newly extracted pinnate compound leaves do not show obvious phototaxis, and the plant type is good.

4. Moisture

In order to protect the potted money tree, efforts should be made to create a wet and dry environment for it. In productive cultivation, the plants placed in the greenhouse should be sprayed with water once a day when the room temperature is more than 33 ℃. Because the plant has strong drought tolerance, it is better to keep the basin soil slightly wet and dry, but the occasional excessive watering and fertilizer will not cause root rot. In winter, we should pay attention to spraying water to the leaf surface and the surrounding environment, so that the relative air humidity can reach more than 50%. After the Mid-Autumn Festival, we should reduce watering, or spray water instead of watering, in order to spend the winter safely in the newly drawn tender leaves yesterday. In addition, in winter, we should pay special attention to the basin soil should not be too wet, it is better to be too dry, otherwise under the condition of low temperature, too wet basin soil is more likely to lead to plant root rot, or even death of the whole plant.

5. Fertilizer

The tree prefers fertilizer. In addition to adding appropriate retted cake fertilizer or multi-component slow-release compound fertilizer to the cultivation substrate, the mixed solution of 02.0% urea and 0.1% potassium dihydrogen phosphate can be applied 2 times a month during the growing season, or 20-10-20 (20-20-20) with a concentration of 200~250ppm combined with calcium nitrate. After the Mid-Autumn Festival, in order to enable it to survive the winter safely, the application of nitrogen fertilizer should be stopped and 0.3% potassium dihydrogen phosphate solution should be applied continuously for 2 to 3 times to promote the hardening and enrichment of its young leaf axis and newly drawn leaves. When the temperature drops below 15 ℃, all forms of topdressing should be stopped so as not to damage the roots under the condition of low temperature.

Problems encountered in farming:

1. "the money tree has a lot of white hairs and black bugs".

Answer: in the environment of poor ventilation, poor light, poisonous soil and excessive humidity, the stems and leaves of Artemisia mandshurica are easy to be attacked by bacteria and sucked by shell insects. Small white hairs, caused by fungi, prevention and control methods:

(1) when a small number of diseased leaves are found, they should be removed and destroyed in time, and at the initial stage of the disease, 50% carbendazim wettable powder or 40% chlorothalonil suspension or 1000 times of Shigao and 1000 times of Remidol should be used alternately. Spraying leaves every 10 days for 3 or 4 times, the control effect is better.

(2) Black bugs can be sprayed with 1000 times of chlorpromazine wettable powder or 1000 times of rapid culling, or 1500-2000 times of imidacloprid. Generally, the insecticidal effect is good when sprayed continuously for 3 times, each time at an interval of 7 to 10 days.

2. "there are black spots on the pole of the money tree, and the leaves are a little scorched. The most serious thing is that many poles have rotted away from the roots."

Answer: the stem of the tree rots from the root, which may be caused by too much water, resulting in the anaerobic respiration of the root. Money tree stem, thick leaves, more water storage, but also more drought-resistant, should not be often watered, generally can be watered once a week or two, and thoroughly. As for the withered leaf tip, it can be sprayed on the leaf surface occasionally.
