In the process of growth, the leaves of Fugui tree often turn yellow, which is caused by the imbalance of cultivation and management. Too much or too little water, too strong or too weak sunlight, and too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is not the same. We should carefully observe and analyze the causes and correct them. The following small make-up for you to sort out the reasons and solutions to the yellow leaves of Fugui tree, come and have a look.
The reasons and treatment methods of the yellow leaves of the rich and precious trees are as follows: 1. As a result, the young leaves are dark yellow and lusterless, the top center of new shoots is atrophied, and the branches and stems are small yellow green.
Solution: in this case, soil should be loosened, watering should be controlled, fertilization should be stopped, the heavy can be removed from the basin, and then put into the basin after drying the soil ball in the shade.
2. (Feihuang) yellow leaf caused by excessive fertilization or concentration, especially partial application of nitrogen fertilizer. The new leaves are plump and glossy, but the concave and convex surface of the leaves is not extended, and the old leaves gradually turn yellow and fall off.
Solution: at this time, fertilizer should be stopped and the amount of water should be appropriately increased to dilute nutrients. If potted flowers are short of fertilizer or water or the plants are big and small, and the roots in the pot are aging or too dense, the leaves of flower plants will become thin and yellow. At this time, the pots should be changed and the soil should be changed, usually when the rain comes to the beginning of summer.
3. (alkali yellow) potted plants like acid flowers, such as camellia, Milan, Michelia, azalea, jasmine, etc., often cause chlorosis and yellowing due to alkaline soil reaction. It is shown that the veins, especially the main veins, are still green, and the phenomenon of yellow green alternation is very obvious. With the aggravation of the degree of yellowing, the veins of the leaves gradually lose their green, and then the whole leaves turn white, the leaf edges are scorched, and the leaves are withered, and even the whole plant is dead.
Solution: for this "yellowing" phenomenon, acid fertilizer or acid substances can be used to improve, or often apply alum fertilizer water.
4. (Yin Yellow) flowers like sunshine, often due to insufficient indoor light, resulting in withered leaves.
Solution: at this time, the basin should be moved to outdoor ventilation and lighting. For semi negative flowers, such as asparagus, leaves will turn yellow under strong light, so to avoid exposure to high temperature and strong light in summer, they should be moved indoors or stored in a shade shed. 5. (dry yellow) due to no watering for a long time or less watering, the leaves turn yellow or brown end and brown edge, and the old leaves wither and fall off from bottom to top. However, the new leaves generally grow normally. When this phenomenon occurs, water should be added to make the soil no longer lack of water.
6. (scorching yellow) potted flowers like Chlorophytum, evergreen, and Hosta, etc. when exposed to strong sunlight, their leaves also have brown ends and brown edges.
Solution: this phenomenon occurs, the basin can be placed in the Yin.
7. (hot and humid) yellow leaves of potted flowers that are not resistant to high temperature and humidity, such as Malus pendula, are caused by poor ventilation and improper shading in midsummer.
Solution: therefore, high temperature and high humidity can easily cause the leaves to turn yellow, which can be prevented by ventilation and cooling, and the basin soil can not be too wet.
The maintenance principle of the rich and noble trees: the rich trees are happy with the light. When they are kept indoors, they should be placed in the place with bright light as far as possible. In addition to the high temperature season in summer, other seasons can accept full day light. If placed in a place without light for a long time, the leaves will gradually turn yellow and fall. Fugui trees do not require much water. They prefer a semi dry and semi humid environment. When watering, it is best to "see the dry and see the wet". If the water content is too large, the root system will be injured and pathogenic. However, if the environment is too dry, the leaves will wither and curl. Usually spray water on the blade, the water temperature should be the same as the room temperature, especially in winter, when the water temperature is too low, the blade will be injured. Spray water at the same time to keep the leaves clean, you can often use a soft cloth dipped in some beer to wipe the leaves, so that the leaves will be more healthy and shiny, this method is also applicable to most foliage plants.
The soil of potted rich and noble trees is limited. Remember topdressing. In addition to applying organic fertilizer as base fertilizer, you should also apply fertilizer and water every ten days or so during the peak growth season. If the flowerpot is small, it will limit its root development and affect the absorption of nutrients. In winter, when the indoor temperature is low, the trees will stop growing and enter the dormancy period. At this time, the branches that are not growing well can be cut off to keep the beautiful appearance of the plant. However, if there is heating supply in the room of Huayou in the north, the rich and noble trees will not sleep normally. It should be noted that ventilation should be maintained, heating outlets should be avoided, and the amount of water poured should be reduced. To achieve the above points, it should not be very difficult to raise rich trees.
