Why the leaves of fortune tree turn yellow: cause analysis and treatment

This means that many people who want to plant a chestnut tree or a horse to make a fortune at home. In today's fast-paced life, not everyone has so much time to take care of these plants, so it's easy to get sick, yellow leaves and other symptoms. Today, let's learn how to do with the yellow leaves of fortune tree.

Fortune tree leaves yellow fortune tree leaves yellow reason analysis and treatment methods: 1, environmental change causes fortune tree leaves yellow: environmental change includes soil change. The red loam soil in South China is acid and magnesium element is easy to be lost. Planting flowers and trees that are resistant to alkali or like to be slightly reserved soil, such as fortune tree, belongs to alkaline flowers and trees, so the phenomenon of chlorosis and yellowing between old leaves and veins will appear.

Solution: apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution.

2. Excessive watering will cause the leaves of fortune tree to turn yellow (water yellow): when the water is too much, the soil in the basin will be too wet, which will make the soil lack of oxygen. Once the soil is lack of oxygen, some roots of fortune tree will rot, fortune tree will not be able to do normal "breathing" and absorb nutrients, and the leaves of fortune tree will turn yellow.

Solution: we usually be careful. When the soil surface in the basin of fortune tree is basically dry, we can pour some water on it.

3. Long term water shortage causes the leaves of fortune tree to turn yellow (dry yellow): Although fortune tree does not like water, if it is not watered for a long time, or only a small amount of water is watered after a long period of time, its roots will not be able to absorb nutrients, so this is also a reason for the leaves of fortune tree to turn yellow.

Solution: usually appropriate watering.

4. Exposure to the sun causes the leaves of fortune tree to turn yellow: Although fortune tree is resistant to drying, in the hot summer, if you forget to move it to a cool place, when it is exposed to the strong sun for a period of time, it will also cause the leaves of fortune tree to turn yellow.

Solution: when exposed to the sun in summer, it should be transplanted to the indoor shade.

5. Air drying causes the leaves of fortune tree to turn yellow: when the indoor air is too dry, some flowers that like humid environment, such as Chlorophytum, orchid and so on, often appear the phenomenon of leaf tip drying or leaf edge scorching.

Solution: should pay attention to take water spray, plastic film cover and other methods to increase air humidity.

6. The lack of sunlight causes the leaves of fortune tree to turn yellow. In fact, fortune tree likes the sunshine very much, but you can't expose it to the sun in the hot weather, but if you put it in a cool place for a long time and can't see the sun, it can't carry out normal photosynthesis, so it can't grow normally, so it will also lead to fortune tree The leaves turn yellow.

Solution: shine some astigmatism outside in the right weather.

7. If the room temperature is too high, the transpiration of the plant is too high, and the water and nutrients in the root are in short supply, the leaves will also turn yellow.

Solution: please adjust the room temperature in time.

8. Low temperature leads to yellow leaves of fortune tree: low room temperature in winter makes flowers with high temperature preference vulnerable to cold damage, which leads to yellow leaves, and sometimes withers and dies.

Solution: please adjust the room temperature in time.

9. Excessive fertilization of fortune tree results in yellowing of leaves (yellowing of fertilizer): if too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly. In addition, they will not be pruned for a long time, resulting in insufficient light of branches and leaves in the inner bore, which is easy to cause yellowing and falling off of leaves.

Solution: reasonable fertilization and pruning should be strengthened to make it ventilated and transparent.

10. The long-term lack of fertilizer of fortune tree results in the yellowing of leaves (lack of fertilizer yellow): if we don't apply fertilizer to it, the soil in the basin will have no nitrogen and other nutrients. Once there is no nutrients, the branches and leaves of fortune tree will become thinner and weaker, and then the leaves will turn yellow and fall off.

Solution: pour the pot in time, change into a new loose and fertile culture soil, and gradually increase the application of thin rotten liquid fertilizer or compound flower fertilizer.

11. Rotten roots cause yellow leaves of fortune tree: rotten roots and yellow leaves of fortune tree are generally caused by accumulated water in basin soil.

Solution: just change the soil and remove the rotten roots. At ordinary times, we should pay attention to prevent ponding, do not dry and do not pour. Generally, we should water once a week under normal temperature.

12. Diseases and insect pests lead to the yellowing of the leaves of fortune tree: leaf spot caused by fungi and other pathogens is easy to cause local necrosis of the leaves, yellow spots or patches. In serious cases, the whole leaves wither and fall off, and yellow and green patches appear on the leaves after infected by mosaic virus; when damaged by scale insects, red spiders, etc., the leaves will also become local withered, or even the whole leaves wither and fall off.

The solution should be timely spraying.

Rich tree rich tree maintenance experience: 1, pay attention to the sun. Fortune tree like high temperature, humidity and sunlight, not long shade. Therefore, in the maintenance and management, it should be placed in the indoor sunny place. When placing, the leaves must face the sun. Otherwise, the whole branch and leaf will be distorted due to the light tendency of the leaves. In addition, every three to five days, spray water to the leaves with a watering pot, which is not only conducive to photosynthesis, but also makes the branches and leaves more beautiful.

2. Pay attention to watering. Watering is an important link in the process of maintenance management. If the water quantity is small, the development of branches and leaves will be stagnant; if the water quantity is too large, the rotten roots may die; if the water quantity is moderate, the branches and leaves will be enlarged. The first principle of watering is rather wet than dry, followed by "two more and two less", that is, more watering in high temperature season in summer and less watering in winter; more watering for large and medium-sized plants with vigorous growth and less watering for small plants newly planted in pots. When the amount of water is too large, it is easy to rot the root of the plant, leading to the drooping, tarnishing and even falling off of the leaves. At this time, it should be moved to a cool place immediately, and the amount of watering should be reduced to the minimum. As long as the basin soil is not dry, spray water on the leaf surface several times a day with a spout, and stop fertilizing water. It can gradually slow down in about 15 to 20 days.

3. Pay attention to fertilization. Fortune tree is a kind of fertilizer loving flower and tree, and its demand for fertilizer is greater than other common flowers and trees. When changing pots every year, the proportion of fertile soil can account for 1 / 3, or even more. The source of fertilizer soil is wide, it can collect the humus soil of broad-leaved tree leaves, add a little garden soil and mixed with bone powder and bean cake residue. The effect of this fertilizer is high, convenient and easy to get, but we should pay attention to fully decay, so as not to "burn" the leaves yellow. In addition, in the growth period of fortune tree (May to September), the decomposed liquid fertilizer or mixed flower fertilizer can be applied every 15 days to promote deep roots and luxuriant leaves.

4. Pay attention to temperature and humidity. Fortune tree has high requirements for temperature and humidity. If the temperature is low or the humidity is missing, the phenomenon of falling leaves often appears. In serious cases, the branches are bald, which not only hinders the ornamental, but also easily causes plant death. Therefore, it is necessary to keep the temperature above 15 ℃ and spray water on the branches and leaves to increase the necessary humidity. In late autumn and winter, we should pay attention to the winter cold, antifreeze management and protection.
