Green pineapple leaves turn yellow? The solution is all here.

Green pineapple is recognized by flower friends, one of the best flowers and plants, not only green decoration environment, but also can eliminate formaldehyde, have a certain effect of cleaning the air.

Many flower friends have raised green pineapple, and basically everyone has encountered the problem of green pineapple leaves yellowing. Sometimes, green pineapple leaves turn yellow, and sometimes only some of the leaves turn yellow, and green pineapple does not find any other problems in a short period of time.

Today, several reasons for the yellowing of green radish leaves and ways to avoid them are summarized.

1. Lack of nutrients

Many hydroponic green pineapple will have this problem. The leaves before hydroponic cultivation are healthy and healthy, and the leaves that grow out after inserting water are all yellow and weak. This situation shows that the leaves are lack of nutrients, and it is very likely that there is a problem with the water quality itself.

In this case, you should avoid using tap water for hydroponics. It is best to use cold boiled water or Rain Water. During maintenance, drop one drop of nutrient solution into the water every month, change the water at least once every two weeks and remove the rotten roots. Soil culture will also appear, especially the new leaves become yellow and thinner, thin fertilizer can be applied.

Second, excessive fertilization

The new leaves are thicker, the surface is uneven, the color is dark, and some of the old leaves turn yellow or even fall off (not one or two). It may be that the amount of fertilization is not mastered, resulting in root system burns.

The amount of fertilizer should not be too much each time. Remember to water after fertilization to avoid the yellowing of leaves caused by fertilizer damage.

Third, too much light.

The light here is too strong and does not necessarily appear under direct conditions. In many cases, even under the condition of astigmatism, green pineapple will turn yellow and black at the tip or edge of some leaves. Careful observation shows that the leaves with problems are generally on the side with strong light. The problem of uneven illumination of leaves at this time.

Maintenance, it is best to put in the light around the uniform astigmatism environment, the most do not put near the window, never change the position direction, it is easy to appear leaf tip leaf part yellow and dry.

Fourth, lack of light

Green pineapple is an attractive plant, but if it is placed in places with poor light conditions for a long time, it is easy to affect photosynthesis, lack of chlorophyll, yellowing leaves as a whole, not energetic and not beautiful enough.

Green pineapple occasionally see a mild direct light is also good, such as every morning before 10:00, can bask in the sun, will not cause sunburn problems, but can promote green apple health, make the leaves greener.

Fifth, insufficient ventilation

All animals and plants like fresh air, and so do green pineapple. If the environment is not ventilated for a long time, many leaves will turn yellow together, and other problems will occur one after another.

If the maintenance environment at home is not ventilated, we must pay attention to the proper replacement of ambient air to create a ventilated environment for green pineapple, so as to avoid poor breathing in the roots and unhealthy leaves.

Sixth, diseases

Green pineapple disease occurs, the leaves will partially change color, and spread to other leaves, generally due to improper temperature and ventilation environment, caused.

In such a situation, it is necessary to remove the diseased leaves in time, spray fungicides, pay attention to the temperature is not too high or too low, regular ventilation.

Seventh, the normal old leaves are withered and yellow.

Healthy green pineapple, under normal metabolic conditions, there will also be a yellowing of one or two leaves at the bottom, slowly withering and withering, which is a normal phenomenon. There is no other problem as a whole, so we can ignore it.

Tips for promoting green pineapple health:

1. Scrubbing the leaves regularly or spraying water on the leaves can promote the health and luster of the leaves.

two。 Nitrogen fertilizer is the main fertilizer and potassium fertilizer is the auxiliary fertilizer.

3. Place next to the window in the east, turn the flowerpot the next day, or the middle position of the north-south transparent living room is more appropriate.

4. Stay away from air conditioning, television, heating and other locations where there is wind or thermal radiation for a long time.
