What should we do at this time? In fact, it is very simple to find out which cause it is, and then solve the problem. Here are the causes and solutions for the yellowing of the leaves of 6 kinds of pineapple.

Second, the causes and solutions of pineapple leaves yellowing.

1. Environmental change

Many flower friends' pineapple flowers are bought directly from the store, at first it is still good, but after a period of time, the pineapple leaves yellowing symptoms appear. At this time, we should consider the problem of environmental changes. Pineapple may change greatly because of the growth environment, and can not adapt for a while, resulting in yellowing symptoms of leaves.

The solution: if you buy online, say hello to the shop owner about the growing environment of the pineapple, and then we slowly change the environment to let the pineapple gradually adapt. I believe that in less than nine years, its leaves will return to health.

Solution: when watering too much: stop watering immediately, loosen the soil, and then move the pineapple to the ventilated place to blow. Or more simply, directly change the basin and soil to make the pineapple flowers refreshing again; when watering too little: properly water, and add a small amount of water to the leaf tube. After a period of time, the pineapple returned to health.

4. Lack of light

Pineapple, originally grown under trees in tropical forests, likes a semi-shady environment, but proper light is also necessary. So some flower friends do not let it shine enough light for a long time, which is also one of the reasons why the leaves of pineapple turn yellow.

Solution: it is found that the leaves turn yellow caused by lack of light, and flower friends should keep them in adequate light every day. The sun is too big for shade in summer, and at least 4-5 hours of light for a period of time in winter.

5. Excessive fertilization or lack of fertilizer

In the process of flower growth, proper fertilization is critical, as well as for pineapple. However, improper fertilization is also very troublesome, which will cause the leaves of pineapple to turn yellow. Excessive fertilization, the new leaves are thick, the old leaves will appear yellowing symptoms, accompanied by shedding; lack of fertilizer: pineapple branches will become thin, leaves will become thin, and yellowing symptoms will appear.

Solution: excessive fertilization: immediately stop fertilization, proper watering and dilution, make fertilizer flow out of the drainage hole at the bottom of the basin; too little fertilization: need to pour the basin in time, change into new loose and fertile culture soil and gradually apply thin mature liquid fertilizer or compound flower fertilizer. After doing this for a period of time, the pineapple will return to health.

6. The temperature is too high or too low

In addition to the above reasons, there is another reason for the yellowing of pineapple leaves, that is temperature, which is easy to be ignored. If the temperature is too high, the growth of pineapple will slow down, and the leaves will slowly turn yellow; if the temperature is too low, there will also be yellowing.

Solution: the best growth temperature of pineapple is 21-28 ℃. When the temperature is too high, it can be ventilated and poured with proper amount of water; when the temperature is too low, antifreeze can be sprayed and the temperature can be raised appropriately.

Because the original state of pineapple is parasitic under a tree in the tropical rain forest and so on, habits like semi-shade, should prevent hot sun exposure, should be placed in half-shade or bright indoor or window.

When dispensing fertilizer, it is directly mixed with deionized water. Generally speaking, the proportion of nitrogen, phosphorus and potassium in it is 201020, because pineapple does not like too much phosphate fertilizer. If there is too much phosphate fertilizer, it will affect the growth of its root system.

Then nitrogen and potassium are preferred, but if there is too much nitrogen fertilizer, it will also cause the leaves to grow excessively. Generally speaking, the ratio of nitrogen fertilizer to potassium fertilizer is about the same, nitrogen, phosphorus and potassium 201020. The general fertilization cycle is about half a month, and during its growth, you can take it out of the basin and observe the color of its root system. If the color of the root is dark, it proves that its fertilizer concentration is more suitable for its growth. If the root is a little white, you can appropriately increase its concentration or shorten the interval period. When applying fertilizer, we should pay attention to increase the application of potassium fertilizer and magnesium fertilizer, reduce the amount of phosphate fertilizer, and strictly control the application amount of copper and boron.

Culture methods and precautions of pineapple plants of different genera tolerate different degrees of light. Some people can withstand full tropical sunlight, while others may soon burn. In general, however, pineapple plants prefer well-lit, bright windowsills rather than direct sunlight. A south, west or east window is often perfect. Yellow plants may receive too much light, while plants are dark green, or elongated, and may receive too little light. The temperature of the water Phoenix pear flower is very resistant to drought.

4. Poor drainage caused the root of the pineapple to rot.

Pineapple is native to the tropics and is afraid of the cold, so the temperature should reach more than 5 ℃ in winter, so as to avoid pathological changes. Because the original state of the pineapple itself is parasitic in the tropical rain forest, so the need for sunlight is not too high, but more sunlight, but also lead to yellow leaves, flower tips dry and so on. Therefore, the place where the pineapple flowers are placed had better be in a semi-overcast and ventilated place to prevent the exposure of the hot sun.

The conditions for raising pineapple flowers also need water. Generally speaking, we breed pineapple flowers in pots at home, so the potted soil of pineapple flowers keeps the surface slightly dry and can not be too wet. If it is more than wet, it will easily soak the roots. How to keep this moisture? There is a leaf tube at the root of the pineapple leaf, and there is a sink in the leaf tube, as long as there is water in the sink. But the water inside had better be changed every half a month so as not to stink. Usually sprinkle some water on the flowers and leaves.
