What about the yellowing of green pineapple leaves? the cause of the yellowing of green pineapple leaves.

What if the green turnip leaves turn yellow at home. If you are still worried about the yellowing of the green pineapple leaves raised at home, I will tell you how to deal with such a situation.

First, what if the green pineapple leaves turn yellow?

On the whole, the leaves of green pineapple are yellow. if they are cultured in hydroponics, there are bacteria in the water, and if they are cultivated in soil, the roots may be rotting. Relatively speaking, the probability of yellow leaves in hydroponic green pineapple is higher than that in soil culture.

First, the reasons for the yellowing of green apple leaves.

The main causes of green apple leaves yellowing are: 1 too much watering, 2 lack of sunshine, 3 lack of fertilizer

First of all, the green pineapple itself is not resistant to low temperature, low temperature for a long time and large water will lead to root rot, resulting in insufficient water supply to the root, and finally the root leaves begin to turn yellow, and the top leaves lose their luster and feel soft with their hands. Try filling the roots with rotting spirit. If it doesn't work, you can only cut off the branches without yellow leaves and re-insert them. In winter, the potted soil is kept slightly dry and unwatered.

Secondly, there is another situation, if there is no problem with the root system, it is the reason for the lack of fertilizer, and the long-term lack of nitrogen fertilizer will also lead to the yellowing of the root leaves, in which case the top leaves still have texture.

Second, how to deal with the yellowing of green apple leaves

1. Illumination: the original growth condition of green pineapple is in the forest sheltered by towering trees, and the positive direction is not strong. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, its illuminance should be increased. The way is to put the green pineapple in the place with the best indoor light, or move to the sealed balcony to bask in the sun at noon. At the same time, open windows as little as possible when the temperature is low, because the leaves may be frostbitten in a very short period of time.

2. Temperature: in the north, the green pineapple can survive the winter safely when the room temperature is above 10 degrees. When the room temperature is above 20 degrees, the green pineapple can grow normally. In general, it is not a big problem for families to reach this temperature, we should pay attention to avoid excessive temperature difference, and at the same time, we should also pay attention to the leaves not close to the heating equipment.

3. Humidity: refers to the water content of the air in the plant growing environment. Under the condition of ensuring normal temperature, increasing humidity is very beneficial to the growth of plants. The following methods can be used to increase the temperature. Keep the plant close to the humidifier, which opens for more than 5 hours a day, and the plant can enjoy the water mist emitted by the humidifier; spray water on the leaves, stems and air roots of the plant with a sprayer adjusted to the fog scale, several times a day; keep the right amount of water in the flowerpot tray and increase the local temperature of the plant through its evaporation Gently wipe the leaves with cold wet towels or toilet paper or apply them lightly for a short time (1m / d for 2 hours); cover the plants with transparent plastic film to create the effect of a small greenhouse and replenish the plant's water by evaporating water vapor in the soil for less than 2 hours a day. Too long time will affect plant ventilation and photosynthesis.

4. Water: the amount of water in autumn and winter should be strictly controlled according to room temperature. Before heating, the temperature is lower and the soil evaporation of the plant is slower. In order to reduce watering, the amount of water should be controlled between 1/4 and 1/2. Even after heating, watering should not be too frequent, watering should be less watered into the basin, and should be oozed by brown silk. In addition, water should be sprayed to the aerial root growth of the brown column to reduce the insufficient water absorption of the root caused by rapid evaporation. Winter water to dry after a day of water is better, the water is too cold easy to damage the roots.

Fertilizer: in autumn and winter in the north, plants grow slowly or even stop growing, so fertilizer should be reduced. Before winter, liquid inorganic fertilizer is mainly poured and sprayed, and the time is about 15 days. After winter, fertilizer is mainly sprayed on the leaf surface, mainly sprayed through the stomata on the leaf surface, and the fertilizer is absorbed through the stomata on the leaf surface, and the fertilizer effect can act directly on the leaf surface. Foliar fertilizer should use special fertilizer, ordinary inorganic fertilizer is not easy to be absorbed by foliar.

III. Solutions

Because the green pineapple can be cut and propagated, it has a leaf bud on each root, so it can grow as long as one node is planted.

Therefore, when the leaves of the farmed green gong are yellowed seriously, the rotten roots can be removed, and the yellow leaves can be removed and re-planted, and pay attention to the replacement of new water in hydroponics.

You can also cut off the branches that do not have yellow leaves and replant them. In the process of planting, it is necessary to bury two to three sections, hydroponic culture is also two to three sections, and in three or four days to change the water, cold boiled water is better.

When just planting, it can not be directed by strong light, but can be placed in a position with weak light, and the newly planted green gong will take root and grow in about 20 days.

Second, the green pineapple leaves are black.

First, the main reason is: the first is that there is too much water. The second is that there may be mold.

2. How to deal with:

1. The treatment method of pouring too much green radish water

Local people should pay attention to water control, otherwise there will be lack of oxygen. Green pineapple grows slowly, so watering should be strictly controlled.

2. The solution to the occurrence of mold in green pineapple.

Green pineapple is easy to raise, but it is also easy to mildew the roots. For some green pineapple that has been cultivated for a long time, I cut it out and insert it again. When the original soil is turned out, you will see a lot of moldy roots. It takes a long time to be exposed in the sun before you start to use it again.

And remove the yellow leaves for re-planting, pay attention to the hydroponic culture, to be replaced with new water.

You can also cut off the branches that do not have yellow leaves and replant them. In the process of planting, it is necessary to bury two to three sections, hydroponic culture is also two to three sections, and in three or four days to change the water, cold boiled water is better.
