What is the matter with the yellowing of the leaves of the beckoning tree, and the yellowing of the

Leaf blight control methods:

1) Remove the diseased leaves in time and destroy them.

2) In the cultivation process of the fortune tree, the maintenance management should be strengthened, timely watering and fertilization, and foliar fertilizer can be fertilized 2-3 times per growing season, such as 200 times of potassium nitrogen phosphate dihydrogen phosphate or double-effect micro-fertilizer.

3) Before the seedlings are transported from the south to the north, the foliar spray of protective fungicides, such as 70% chlorothalonil 800 times solution, or 18% multibacterial copper milk powder 200 times solution, or 50% antibacterial special 600 times solution, after being transported to the north, should be planted in time, strengthen fertilizer and water management, and prevent dehydration and fertilizer. The cultivation of fortune trees in southern China can be sprayed every 10-15 days with 50% carbendazim 800 times, or 70% chlorothalonil 800 times, and 75% methyl tobuzine 1500 times every 10-15 days.

This condition may be caused by different factors, if you look closely at the wilted area, the wilted edges are darkened, and there are small brown dots or black dots on them, indicating leaf blight. Leaf blight means that your plant itself is not growing well. If it is not leaf wilt, it may also be caused by malnutrition.

Here are some experiences in raising a fortune tree and hope it will help you. The fortune tree has a beautiful posture, the leaf crown is majestic, the leaf color is emerald green, and it is placed in the family living room, which is both elegant and generous, and attracts people's love. Fortune tree for.

1.Improper lighting

Too strong light: The beckoning tree likes light and avoids strong light. While giving it enough light, shade it out when the light is strong. If the flower friend exposes the beckoning tree to direct sunlight in the summer, it is easy to cause burns, and there will be symptoms of yellowing and falling leaves of the beckoning tree.

Solution: Move the maneki tree to a ventilated semi-shaded place and water it properly until the yellow leaves slowly fall off and then grow new shoots.

Lack of light: During the cultivation process, if the tree is not pruned in time, the branches and leaves will grow very densely, and the leaves hidden at the bottom will turn yellow due to insufficient light and lack of ventilation.

Solution: Lucky trees grow faster. We should prune once a year. Don't be reluctant. Only when it is done will it become more beautiful.

2.Overwatering

The tree has strong drought tolerance, underdeveloped root system, poor water absorption ability, and should not be watered too much. Once you water too much, it will cause water to accumulate in the pot, which is easy to cause the root rot of the plant. As a result, the leaves of the lucky tree turn yellow and fall off.

Solution: Stop watering and move the maneki tree to a ventilated area to allow the water in the pot to evaporate quickly. To speed up the process, you can spread a layer of absorbent cotton cloth on the bottom of the pot. If there are rotten roots, cut them off and replant them with soil.

3.Excessive fertilization

After talking about watering, let's talk about fertilization, which is also one of the reasons why the leaves of the beckoning tree turn yellow. The Lucky Tree likes to fertilize, but if it is too much or too much, it will burn the rhizome, causing the leaves of the plant to turn yellow, and even die in severe cases.

Solution: Can be diluted with watering; But if it is found in time that the roots are badly burned, the potting soil needs to be replaced and the rotten roots cleaned up. After a period of maintenance, the plant will regain its health.

4.Temperature discomfort

Lucky trees prefer warm environments, are not tolerant to high temperatures or cold, and are optimally grown at 20-30 temperatures. Once the temperature is too high or too low, it will affect the growth of the lucky tree, resulting in the symptoms of yellowing of the leaves.

Solution: Adjust the temperature. In summer, move the plants to a cool place and sprinkle water to cool down; In winter, move it indoors to raise the temperature. After a period of maintenance, the leaves of the beckoning tree will regain their brilliance.

5. Pest and disease infestation

In the process of cultivation, beckoning trees are often pests and diseases due to improper maintenance or poor environment. This is also one of the reasons why the leaves of the manekiki tree turn yellow and fall.

6. The soil is alkaline

If the above points can be ruled out, then the yellowing and defoliation of the maneki tree may be caused by alkaline soil. It is known that lucky trees prefer acidic soils. If pots are not replaced frequently, the soil will become more alkaline, and the roots of the plants will affect nutrient uptake.

As a result, the leaves will slowly turn yellow.

When breeding the beckoning tree, you need to control the frequency of watering, you can water it every half a month, and you should place the lucky tree in a well-lit environment, and apply liquid fertilizer every two months.

When breeding the beckoning tree, it is necessary to control the frequency of watering, you can water it every half a month, and the beckoning tree should be placed in a well-lit eggplant environment, and apply liquid fertilizer every two months.

Low temperatures cause the Fortune tree to be adapted to high temperatures, growing between 25-30 degrees Celsius. Before the weather changes from warm to cold, the temperature is cold, and the leaf tissue will be injured and fall. Water less at low temperatures. If it's the south, it won't be fine, water less, and water it after the pot dries.

Problem 2: Too much water, causing the roots to rot, although the main stem has not yet seen the rot, but the leaves will appear, just like a person is sick, the first will be shown on the face. The truth is the same.

Problem 3: Excessive fertilization will cause the edges of the leaves to burn or turn white as the whole leaf. The soil in the pot cannot be moved in this season, and the soil in the pot may hurt the roots, and it is not easy to heal in this season.

Only remove the floating soil on top with visible fertilizer. and water to dilute. Watering a few more times after the water has flowed out A few days later it is enough to water the soil after it has dried.

Question 4: Just bought after the fortune tree, in winter should be careful not to use the phoenix to blow, for a long time by the cold wind to blow, the outdoor temperature is 6 degrees, on the transport of the car on the top of the about 2 degrees. The leaves turn yellow when they arrive home.

When buying, pay attention to the need for protection of leaves. Wrap in newspaper or plastic paper.

Xiaoyou gives you two tricks, the first is to water too much caused by the yellowing of the leaves and fall off, check whether the root system is healthy, directly turn the pot, cut off all the rotten roots, and soak it in mancozeb or carbendazim solution for half an hour! The second point is that the leaves are yellow and fall off due to the temperature being too low, and thermal insulation measures should be taken in winter, and they should not be placed outdoors or on open balconies.
