What are the reasons for the yellowing of the leaves of the fortune tree?

Everyone likes the fortune tree . Planting the fortune tree is to bring feng shui and wealth to the home. The cultivation method of the fortune tree needs to be treated with caution. What should we do if we find that the leaves of the fortune tree turn yellow during the planting process ? Let's talk about the cultivation information of the fortune tree .

What causes the leaves of the fortune tree to turn yellow?

1. Improper watering: The fortune tree likes a warm and humid climate environment, and the pot soil should be moist. However, for indoor cultivation, the pot soil is generally not dry before watering, and water thoroughly when it is watered. Because if it is not watered thoroughly, the top is wet and the bottom is dry, which will affect the absorption of nutrients, causing the leaves to be dull and lusterless, and gradually wither and fall off from the bottom to the top. In this case, it is necessary to water it in small amounts and spray it frequently to allow it to gradually recover before switching to normal watering.

2. Unsuitable light: The fortune tree likes light, but cannot tolerate strong direct light. It is suitable to be in semi-shade or scattered light.

In the late April, you can choose a sunny and warm noon, move the pot outside or to the balcony, expose it to direct sunlight for 1-2 hours, and gradually extend the time, which will have a good breeding effect. If it is kept in the shade or dim light for a long time, the leaves will turn yellow and fall off, and in severe cases, it will die.

3. Disease and pest control: Leaf spot disease is a common disease of the fortune tree. The symptoms are that a few spots appear first, and then the spots gradually expand and extend to the entire leaf and fall off. Garlic juice can be used for spraying to sterilize. As for insect pests, the main hazards are red spider mites and scale insects. Red spider mites are small, with a body length of less than 1 mm. They can be effectively controlled by mite net, mites, trichlorodiphenyltrichloroethane, etc. Scale insects vary greatly depending on the species, but they have one common feature, that is, they are round or oval, generally do not move, and suck juice from the stems or petioles of the plant. When there are few, you can wipe them clean with a cloth strip, because the scale insects will die as soon as they leave the plant. When there are many, you can spray a 0.2% solution of wind oil and laundry detergent for prevention and control.

4. Too much fertilizer: Generally, during the growth period of the money tree, fertilizer should be applied regularly to ensure the lush growth of the plant. Generally, thin fertilizer should be applied every 20 days or so, and well-rotted basal fertilizer should be added when repotting. If too much fertilizer is applied, or the fertilizer is not well-rotted, it will cause the roots of the money tree to burn and the leaves to turn yellow and fall off.

5. Dust on the leaves: If the dust on the leaves is too thick, it will not only affect the appearance, but also affect the respiration and photosynthesis of the plant, thus causing the leaves to turn yellow. The dust should be wiped clean in time.

6. Incorrect soil replacement: When changing the soil, incorrect operation will also cause the leaves of the money tree to turn yellow. When changing the soil for the money tree, try to minimize root damage. The added substrate should be sterile, breathable, fertile, and slightly acidic. The potting soil should be filled without leaving any gaps. If there are gaps, no matter how much water is poured on the plant, it will still lack water, causing the leaves to turn yellow.

7. Low environmental temperature: The money tree likes warm and humid environment. Its suitable temperature for growth is 20-30℃. If the temperature is lower than 18℃, the money tree will stop growing. It can also adapt to temperatures as low as 10℃, but the minimum temperature cannot be lower than 5℃, otherwise frost damage will occur, and the leaves will turn yellow and scatter in mild cases, or die in severe cases.

8. Heat and high temperatures: For the money tree that likes a warm and humid environment, if it is exposed to high temperatures, the plant's transpiration will be excessive and the roots will not be able to meet the demand for water and nutrients, which can easily cause the leaf tips to burn or the leaves to turn yellow and fall off. It needs to be moved to a well-ventilated, cool place in time.

9. Tight and poor ventilation: If the branches and leaves of the money tree grow too lush and have not been pruned for a long time, the inner branches and leaves will not receive enough light, which can easily cause the leaves to turn yellow and fall off. Pruning should be strengthened in time to allow ventilation and light to pass through.

10. Alkaline soil: The soil and water in most areas of the north contain more salt and alkali, which is not suitable for planting the acid-loving money tree. Because the soil lacks iron that can be absorbed by the tree, the leaves of the money tree will gradually turn yellow. Therefore, you should pay attention to the use of acidic soil when planting, and frequently irrigate with alum fertilizer during the growth period.
