The causes and treatment methods of the withering and dying of the rich tree

Because of its special tree shape, and stem base can be processed into different shapes, the meaning of the name is particularly good, so it is often used as an indoor foliage plant is widely cultivated. However, some flower friends often raise rich trees to die when planting rich trees. What is the reason for this? How should we deal with it?

fortune tree

Fortune trees are native to the tropics, like full sunlight and high temperatures, and grow rapidly when sunlight, temperature and moisture are sufficient. However, it is also very resistant to shade, and it can grow well anywhere indoors in the short term. However, every 10 to 20 days, the rich tree should be moved to an outdoor sunny place for a period of time, otherwise the leaves will be too thin. It's best to put it in a place where there's bright scattered light.

The appropriate temperature for the growth of rich trees is 15~30 degrees. In winter, proper attention should be paid to heat preservation. Low temperature is easy to cause deciduous leaves.

Watering is the key content of tree maintenance, summer, when it grows vigorously, water absorption, every 2 to 3 days that is, the need to water 1 time, if it is in the open air, then water 1 to 2 times a day. However, watering is not the more the better, but also the principle of dry and thorough watering, so that the soil dry and wet have an intermittent time.

Fortune tree grows rapidly, in the case of good fertilizer and water, it can grow about 1 meter per year. It must be pruned frequently to maintain a good tree shape. When pruning, most of them adopt the method of flat shear, but they can also be carried out according to personal requirements. No matter how thick or thin the pruned branches are, as long as they have been lignified, they can be cut into cuttings 20~30 cm long and inserted into flower pots for reproduction. However, the cuttings survived generally not easy to grow into a tree with expanded stem base.

How to save money and save money in winter

Lucky name of the rich tree is the best ornamental plants, a small pot at home, sustenance of "lucky" good wishes. However, the cold-resistant ability of the rich tree is poor. When cultivating the rich tree in winter, we should pay attention to several aspects such as temperature, moisture and light. The following small series introduces how to raise the rich tree in winter to save the frostbite!

How do you grow trees in winter?

I. Light

Fortune tree in the full sunlight environment to grow strong, leaf nodes short, wide leaves, dark green leaves, and stem base hypertrophy robust. If long-term growth in weak light, then thin branches, petioles droop, leaf color becomes light green. The best way is to move the potted tree outdoors in the middle and late March of the following year at noon on a sunny day. Start seeing sunlight for 1 - 2 hours a day, and then gradually extend the sunlight time until full sunlight management is restored.

II. Smoke

Winter fortune tree moved to indoor maintenance, to avoid exposure to smoke hazards. Smoke yellows the leaves and reduces their ornamental value. Therefore, try not to put the rich tree plant in the smoke mouth or air conditioning outlet.

III. Temperature

The most suitable temperature for the growth of Fortune Tree is 20℃~30℃, and the winter temperature is controlled above 5℃. Fortune Tree can generally survive the winter safely. If the room temperature is lower than 8℃, and the environment is too humid or dry, and there is no ventilation, the leaves of Fortune Tree will appear water-stained spots, which will first appear bronze and then gradually fall off. If the temperature is lower than 5℃, all the leaves of the tree will fall off or even die.

Therefore, in mid-November, the potted fortune tree was moved indoors for winter, and the next year's grain rain (mid-April) was moved outdoors.

IV. Moisture

Fortune tree is not very strict with water requirements, outdoor flood irrigation or indoor 10 days without watering, can grow normally. But winter watering should reduce the amount of watering. Fortune tree basin soil bogey wet, to slightly damp is appropriate, otherwise rich leaves tip easy to dry coke, even leaves fall off. The room temperature is between 12 and 18℃, and the tree can be watered once a month. diyju.com

How to save frostbite in rich trees

In winter, improper maintenance of rich trees is prone to frost damage. The leaves and roots of rich trees that are not cold-resistant are easy to frostbite. Once frost damage occurs, it needs to be remedied in time. Otherwise, rich trees are difficult to live.

First, move the potted plant to a warm place. Then, check the degree of frost injury of the tree, if only the leaves are damaged, spray the leaves with butyl naphthylacetate and gibberellin solution, and irrigate the roots with naphthylacetic acid and other chemicals. Once every 3 days, after the tender leaves grow out, once every 7 days, generally 5 ~6 times can recover.

When the roots of Fortune Tree are found to be damaged, the solution of 200 times of B-Mn wettable powder with a concentration of 70% can be injected, and then the Fortune Tree potted plant is placed in a warm and dry place to resume growth.

How to make a rich tree yellow leaves?

I believe many people will put a pot of fortune tree at home or in the office. First of all, the meaning of fortune tree is very good. In addition, the tree shape of fortune tree is very beautiful, with bright green leaves all year round. It is a very beautiful foliage plant. However, improper maintenance of the rich tree will also appear yellow leaves. The following is a description of the cultivation method of the rich tree and the treatment method of yellowing the leaves of the rich tree.

The cultivation method of rich tree

I. Choice of environment

Fortune tree adaptability is strong, like light and shade, full sunshine, half sunshine or shade are growing well. But if you grow in the dark for a long time, your chances of survival will deteriorate. In summer, it is better to shade 50% so as to avoid scorching sun to make leaf tips and leaf margins dry and scorched.

In indoor culture viewing should be placed in a certain scattered light, not for more than 30 consecutive days, such as the phenomenon of poor growth, should gradually accept sunlight, avoid rapid exposure to strong light, in case not adapt to death.

II. Selection of basin soil

Most of the rich trees bought now are the soil brought by the merchants. Flower friends do not have to change the soil at the first time after buying them. They raise them first and then consider changing the soil later. If the soil is changed, the potted plants of rich trees generally use loose vegetable garden soil or peat soil, rotten leaf soil, coarse sand, and add a small amount of compound fertilizer as base fertilizer and cultivation soil.

Third, the rich tree watering

The root system of Fortune Tree is very underdeveloped. Many flower friends die of Fortune Tree because of rotten roots. Some flower friends will ask, how often does Fortune Tree need to be watered and how much water is watered at a time? It should be clearly said here that the situation varies from place to place, and the pots and soil used are also different, so there is no fixed watering standard.

How do you water it? Generally speaking, watering once a month is not too little. In addition, tell the flower friends a tip, that is, the plants will not die soon after water shortage, and will recover soon after watering. However, if the water is basically waterlogged, it cannot be saved. The rich tree can usually spray more water and water less.

Third, rich tree fertilization

Under normal circumstances, if the soil is fertile enough, no fertilizer is needed. If it has been raised for a long time, you can consider giving thin fertilizer instead of thick fertilizer. Fertilization can use some common leaf fertilizer. Remember to be thin fertilizer.

Note: Generally speaking, the fortune tree is cut off, so every spring, flower friends can also give appropriate pruning, on the one hand, it can be beautiful, and on the other hand, it can promote the growth of new branches.

IV. Pay attention to the occurrence of diseases and insect pests

Such as the discovery of black stem epidermis or exposed black filamentous fiber, is stem rot disease and caused by rich tree rotten stem. At the initial stage of the disease, 50% Bactericide should be sprayed with 1000 times of water-soluble powder, sprayed once every 10 days, and continuously controlled 2-3 times.

Anthracnose can be controlled by spraying 800 times 50% chlorothalonil wettable powder or 600 times 50% carbendazim solution every 7-10 days. Such as cabbage caterpillar, geometrid, red spider can regularly spray 40% omethoate 800 times or 50% dichlorvos 1000 times liquid, every 7 days 1 time even spray 2-3 times.

What about the yellow leaves?

1. Too much watering

Basin soil long-term too wet, resulting in lack of oxygen in the soil, so that part of the fibrous root rot, hinder normal respiration and absorption of water and nutrients, causing yellow leaves off. After the first young leaves become pale yellow, and then the old leaves gradually yellow, should immediately control watering, suspended fertilization, and often loose soil, so that the soil ventilation is good.

2. Drought dehydration

Flower cultivation leakage watering or long-term irrigation half-waist water (that is, wet under dry), affecting nutrient absorption, but also easy to cause leaf color dull luster, leaf wilting droop. First, the lower part of the old leaves aging, and gradually from the bottom to the top yellow off. At this time, a small amount of watering and spraying water is needed to gradually restore it and then turn to normal watering.

3. Long-term de-fertilization

Long-term no ammonia fertilizer or no change pot change soil, soil nitrogen and other nutrients lack, resulting in thin branches and leaves, thin and yellow leaves. Need to pour pot in time, change into new loose fertile culture soil gradually increase the application of thin decomposed liquid fertilizer or compound fertilizer.

4. Excessive fertilization

Fertilization too much will appear new leaves hypertrophy, and more uneven, old leaves dry tip yellow fall off, should immediately stop fertilization, increase watering, so that fertilizer from the bottom of the drain hole out, or immediately pour the pot, wash the soil with water and then re-planted into the pot.

5, hot and high temperature

Summer if the sex like cool flowers (such as cyclamen, fuchsia, begonia) on high temperature to let the strong direct sun, easily cause young leaf tips and leaf margins withered coke, or leaf yellow fall off. It should be moved to a well-ventilated cool place in time.

6. Excessive shade

If the flowers like sunlight are placed in shade or insufficient light for a long time, it will lead to yellowing of branches and leaves.

7. Alkaline water and soil

The soil and water in most areas of the north contain more saline and alkali. When planting acid-loving flowers, such as rhododendron, camellia, Michelia, gardenia, orchid, white peony, osmanthus, etc., the leaves will gradually turn yellow due to the lack of soluble iron and other elements that can be absorbed by the soil. Acid soil should be selected for planting, and alum fertilizer should be often poured during growth.

8, not ventilated

If the nitrogen fertilizer is too much, the branches and leaves grow into luxuriant, plus long-term unpruned, resulting in insufficient light in the inner bore branches and leaves, easy to cause yellow leaves to fall off. Fertilization should be rational and pruning should be strengthened to make it ventilated and transparent.

9. Air drying

When indoor air is too dry, some flowers that like humid environment, such as spider orchid, orchid, etc., often appear leaf tip dry or leaf edge scorched and so on. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

10. Improper temperature

Winter room temperature is too low, for high-temperature flowers are often vulnerable to cold damage, resulting in yellow leaves, serious yellow and death. If the room temperature is too high, the transpiration of the plant is too strong, and the root water nutrient is in short supply, which will also make the leaves yellow. Please pay attention to adjust the room temperature in time.

11. The soil is acidic

The red soil in the south is slightly acidic, magnesium element is easy to lose, planting alkali-resistant or light-sensitive soil flowers and trees, such as oleander, boxwood, Yingchun, etc., often prone to green and yellow phenomenon between the veins of old leaves. Calcium magnesium phosphate fertilizer or magnesium sulfate solution can be applied.

12. Pest damage

The leaf spot disease caused by fungi and other pathogens is easy to cause local necrosis of leaves, yellow spots or patches appear, and the whole leaves are withered and fallen off in severe cases. After being infected by mosaic virus, yellow and green mottled appear on the leaves; by scale insects, red spiders, etc., the leaves will also become partially yellow and withered, and even the whole leaves will be withered and fallen off. All should be timely spraying control.

13. Strong sexual stimulation

The use of pesticide concentration is too large when controlling diseases and insect pests, or it is polluted by toxic gases in the atmosphere, or suddenly irrigated with cold water when the temperature is high, etc., which are easy to cause leaf tips or leaf surfaces to be partially yellowed and withered, or even the whole plant to die.

Therefore, attention should be paid to the rational use of pesticides, try to eliminate air pollution sources. Avoid watering flowers with cold water around noon in midsummer. Finally, it should also be mentioned that pot flower yellow leaves are sometimes caused by a cause, but often due to a variety of factors, should make a correct diagnosis, can prescribe the right medicine.

The above is the breeding method of the rich tree introduced for everyone, and some answers to the question of how to do the yellowing of the rich tree leaves. I hope everyone can understand it. Please pay attention to more knowledge of household plants.
