The causes and solutions of yellowing and blackening of white palm leaves and how to do it?

The yellowing and blackening of leaves is a signal to people when plant life is in crisis. Usually the blackening of the leaves of the plant is a sign of dying, but the cure chance of yellowing of the leaves is relatively large. In view of this situation, we need to take timely measures to remedy.

The cause of blackening of white palm leaves and its solution

First, reasons

1. Watering

The main reason for the blackening of leaves in white palms is that they are watered too much. White palm is generally raised indoors, a common feature of indoor plants is poor ventilation, so it is easy to accumulate water in the flowerpot, one of the consequences is that the leaves of white palm will turn black.

2. Fertilization

Fertilization will also affect the leaves of white palm, make it black, this is mainly in the case of too much fertilization will occur, because too much or too thick, will produce the phenomenon of burning roots.

3. Lighting

In the cultivation of white palm, it needs scattered light, strong direct sunlight will make it burn and blacken the leaves, so it must be avoided.

II. Solutions

1. Prescribe the right medicine to the case

If the leaves of the white palm turn black, we must first find out the reason why the leaves are black.

If it is too much watering, first aid measures should be taken to remove the whole plant from the flowerpot, handle it to dry, and then replant it. After that, we need to pay attention to watering, depending on the condition of the basin soil, dry and re-watering to avoid stagnant water.

If you apply fertilizer, you can apply fertilizer with a lower concentration, not too often. And pay attention to maintain the appropriate scattered light.

2. Daily attention

When raising white palm indoors, it is best to pay attention not to change the position frequently, and if you keep it in a cool backlit place for a long time, do not suddenly put it under the strong light, so as to avoid stress reaction.

Pay attention to watering and fertilization, as long as in the daily maintenance of reasonable water and fertilizer management, can play a role in preventing leaves from blackening.

If the white palm blackening leaves are relatively few, only one or two, then you need to wait patiently, usually in the spring, it still grows new leaves. If the quantity is a little more and cannot be recovered, cut it off. Of course, if your white palm leaves are too black, it will be a big problem. Let's see if there are rotten roots.

The solution to the yellowing of white palm leaves

The main results are as follows: 1. Environmental mutation leads to yellowing of white palm leaves: the cause of environmental abrupt change is that the soil, temperature, humidity and light suddenly change too much, or the leaves turn yellow due to the need to slow down the seedlings when the roots are injured in the basin.

Solution: reduce the degree of change in the environment and wait for it to adapt.

2. Too much watering leads to yellowing of white palm leaves (water yellow): although white palm can be hydroponically cultured, it does not mean that soil culture needs a lot of frequent watering, especially when the amount of watering is small and the number of times is large, the water is easy to stay at the joint of the rhizome and cause the growth point to rot to death. It shows that the tender leaves are dark and yellow, and the new shoots are shrunk.

Solution: in this case, the number of watering should be reduced, and each time the water in the matrix is slightly dry and then watered again.

3. Soil alkali leads to yellowing of white palm leaves: White palm likes acidic soil. If planted in the north, due to alkaline water quality and soil quality, long-term application will lead to gradual fading, yellowing and even shedding of leaves.

Solution: the easiest way is to pour fermented rice washing water or Rain Water.

4. Exposure leads to yellowing of white palm leaves (burning yellow): strong direct sunlight is easy to cause withering of leaf tips and edges, and macula appears in the sunny part of leaves.

Solution: just move to the shady and ventilated place.

5. Lack of sunlight leads to yellowing of white palm leaves (lack of light yellow): White palm needs better light in winter and early spring, do not shade.

Solution: gradually shade the sun when the light is getting stronger, and if you enjoy it in the shade, you can't put it in the sun directly. Otherwise, there will be discomfort due to rapid changes in the environment, such as wilting, yellow leaves, and even death.

6. Temperature discomfort leads to yellowing of white palm leaves: the growth of white palm requires a semi-shady place, and leaves are easy to yellowing when the temperature is lower than 5 ℃ or higher than 35 ℃. The leaves are dull and lose their luster. Long-term cryogenic liquid will cause withering and yellowing of the ground.

Solution: adjust the temperature, special circumstances can be moved to the air-conditioned room!

7. Excessive fertilization leads to yellowing of white palm leaves (fat yellow): too much fertilization shows that the old leaf tip turns yellow and withered, and the new leaf is thick and shiny, but the concave and convex does not stretch.

Solution: you can sprinkle a layer of cabbage or radish seeds on the surface and pull them out a few days after emergence to consume nutrients.

8. Diseases and insect pests lead to yellowing of white palm leaves: if harmful mites are harmful, the leaves show bad symptoms such as wilting, gloss desalination, yellow blight and so on.

Solution: special mites can be sprayed for control, such as triclofenac, Nisolang, pyridaben and so on.

2. The basin has not been changed for a long time

Family breeding white palm should timely loosen the soil to change the basin, every early spring to change the basin, check the soil condition, if more caking, it is recommended to break up in the sun after replanting. When planting, half of the old soil is dumped and replaced with loose soil, which is beneficial to the growth of the root system. During normal maintenance, loosen the soil every half a year to increase the oxygen content in the soil. Slow seedling

3. Improper retarding of seedlings

The newly bought white palm should first put the plant in a ventilated and cool place with scattered light and water it properly. It will be transferred to normal maintenance after a week.
