What if the green pineapple leaves turn yellow? What are the solutions to the yellowing of green apple leaves?

Green pineapple is a potted plant that will be often seen at home and in the office environment. Green pineapple is very easy to feed, but if there is too much water or too little sunlight, too much fertilizer will cause the leaves to turn yellow. The situation of yellowing is different, and the cause should be carefully observed and analyzed. According to different yellowing conditions, different measures are adopted in order to raise a good-looking green apple. Let's take a look at the cause analysis and treatment of the yellowing of green pineapple leaves.

Cause analysis and treatment methods of yellowing of green pineapple leaves

1. The sudden change of environment leads to the yellowing of green apple leaves:

The reason for the sudden change in the environment is that the temperature, humidity and light suddenly change too much, or it is necessary to slow down the seedlings when the roots are injured in the pot, and the leaves turn yellow.

Solution: there is no need to worry about this situation, measures can be taken to reduce the degree of change in the environment, waiting for it to adapt.

2. Too much watering causes the green apple leaves to turn yellow (water yellow):

The young leaves were dark yellow and dull, the old leaves had no obvious change, the branches were small yellow-green, and the new shoots shrunk not long, indicating that they were overwatered.

Solution: put the green turnip basin in a cool, ventilated place and wait for the soil to dry before putting it back into the basin.

3. Long-term lack of water leads to yellowing of green apple leaves (dry yellow):

The yellow with lack of water is different from the yellow with more water, the yellow with lack of water is withered and dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal.

Solution: pay attention to watering enough and thoroughly.

4. Exposure to the sun causes green apple leaves to turn yellow (burning yellow):

Strong direct sunlight is easy to cause green radish leaf tip, leaf edge withered, leaf sunrise part of the macula.

Solution: just move to the shady and ventilated place.

5. Lack of sunlight leads to yellowing of green apple leaves (lack of light yellow):

When the leaves were placed in a shady environment for a long time, the leaves could not get enough sunlight and could not form chlorophyll, and the whole leaves turned yellow and fell off.

Solution: move to a place with more light.

6. Excessive fertilization leads to the yellowing of green apple leaves (fat yellow):

The yellowing caused by excessive fertilization or excessive concentration shows that the new leaf tip appears dry brown, the general leaf surface is thick and dull, and the concave and convex does not stretch, and the old leaf is scorched yellow and shedding.

Solution: stop fertilization immediately, seriously rinse part of the fertilizer with a large amount of water, or change the cultivated soil.

7. Long-term lack of fertilizer leads to yellowing of green apple leaves (lack of fat yellow):

The performance is that the color of the young leaves becomes lighter, showing yellow or light green, while the old leaves are more normal or gradually change from green to yellow.

Solution: check the basin soil and change the soil if there is a dry knot. Usually apply thin fertilizer frequently and pour some alum water at the right time.

8. Rotten roots lead to the yellowing of green apple leaves:

The performance is that the color of the tender leaves becomes lighter, showing yellow or light green.

Solution: remove the rotten roots and put them in a ventilated place to dry. Return to the basin after the wound heals, and be careful that there is no stagnant water in the basin.

Maintenance method of green pineapple

1. If you want to remove the yellowing leaves, be careful not to pull them directly. You can cut them from the middle of the petiole with scissors to avoid losing too much water and have a bad effect on the growth of green pineapple.

2. 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.

Experience of potted green pineapple culture

1. There are at least 4 colonized seedlings in the basin. The basin soil should be loose, fertile and rich in organic matter, which is favorable for forming.

two。 Green pineapple is required to grow in an environment with high temperature (room temperature should not be lower than 10 ℃ in winter, otherwise yellow leaves and fallen leaves are easy to occur) and strong scattered light. If it is too dark for a long time, the internodes will be slender and weak, and the leaves will become thinner, lighter and lose luster.

3. In late spring and early summer (April-August), 15-30cm branches are cut, and the leaves with 1-2 basal nodes are removed.

4. Potted directly with culture soil, 3-5 roots per pot, watered thoroughly, planted in a cool and ventilated place, keep the pot soil moist, can take root and sprout in about a month, and grow into plants with ornamental value in the same year.

7 lessons learned from the treatment of green radish and yellow leaves

Lesson 1: green apples bought in winter are generally frozen, so yellow leaves will soon appear indoors, and new leaves will be reissued during the Spring Festival after these frozen yellow leaves have fallen.

Lesson 2: generally, newly bought green apples have an adaptation period of about 1 month to the new environment, and the bottom yellow leaves are normal, but remember: yellow or dead leaves should not be directly peeled off, but should be cut off from the middle of the petiole. in this way, it can avoid direct stripping to cause too much water loss and increase the wound, resulting in yellowing of the upper leaves.

Lesson 3: green pineapple is not afraid of darkness, but a very dark environment can also cause yellow leaves, which can be moved regularly to places with good light. At the same time, it can not be exposed to the sun. Excessive exposure in strong light will not only cause yellow leaves to fall, but also lead to the death of the whole plant.

Lesson 4: when the basin soil is too dry or too wet, both cases will cause metabolic disorders, root damage and yellow leaves.

Experience 5: lack of fertilizer, malnutrition will also appear yellow leaves, fertilizer should be replenished in time.

Lesson 6: you can apply fertilizer with beer appropriately. Method: mix beer with water at 1:1 and spray stems and leaves.

Lesson 7: too much topdressing can easily cause root burning, causing leaves to turn yellow and wilt. You can dilute fertilizer with water to allow nutrients to flow away with the water.

Let's understand the reason why the green pineapple leaves turn yellow.

? The reason for the yellowing of green apple leaves: first, the problem of water. Improper watering is one of the reasons for the yellowing of green radish leaves, green pineapple is very particular about the absorption of water, it is a kind of vine plant that likes wet growth environment, although it likes damp, but the amount of water needs to be appropriate when watering. Excessive watering or no watering will cause green radish leaves to yellowing, if the leaves are dim and no luster belongs to excessive watering, the dry tip or edge of green pineapple is caused by insufficient watering. Second, the problem of lighting. Green pineapple this kind of vine plant generally likes to grow in the shade, exposure or strong light will cause the leaf tip and edge of the plant to wither and the leaves appear macula, which affects the beauty. If placed in a dark environment for a long time, the leaves of green pineapple will also be yellowed because of inability to carry out photosynthesis, so it is best to put it in appropriate light when breeding green pineapple, such as incandescent lamp. Third, the problem of fertilizer. The amount of fertilizer in green pineapple culture is also one of the reasons for whether the leaves are yellowing or not. if green pineapple culture is fertilized too much, too much concentration and lack of fertilizer may lead to the yellowing of green gong leaves. When fertilizing too much, the leaves of the green gong will become thick, dull and comfortable, and the old leaves will turn yellow and fall off. At this time, we need to rinse to reduce fertilizer. When there is a lack of fertilizer, the green radish leaf color will become light green or yellow.

? Green pineapple leaves yellowing how to do-solution 1, green pineapple is a kind of plant that likes the warm and humid growth environment, so the soil condition when breeding is very important, it is best to grow in loose soil, fertile and well-drained soil to effectively reduce the probability of yellowing leaves, while the matters needing attention when potted green pineapple culture is to choose fertile, loose and well-drained rotten leaf soil, if it is slightly acidic. Second, because the green pineapple is a very shade-tolerant type of vine, so unsuitable light conditions will also cause the green pineapple leaves to turn yellow, so what if the green pineapple leaves turn yellow? at this time, we have to provide the green pineapple with suitable light conditions. when growing in the sunny part of the room, remember that you can't get exposure or strong light, and you can't have no light at all.

The water quality had better be clean tap water, do not drink the rest of the water to pour into the pot at will, the soil is too moist will cause the roots of the plant can not breathe, resulting in yellow leaves and rotten leaves. Fourth, to prevent green apple leaves from yellowing, it is necessary to apply appropriate and timely fertilization. it is best to apply thin fertilizer frequently, a small amount of fertilizer for many times, and remember not to apply too much fertilizer at one time, otherwise it will lead to overnutrition, plants can not be completely absorbed, resulting in root burning, yellow leaves and other phenomena, it is best to use organic fertilizer when fertilizing, or you can use beer properly, and spray the stems and leaves of green apple with water according to the ratio of 1: 1 beer.

Conclusion: green pineapple is a typical foliage plant with high ornamental value. Its rattan leaves are well developed and bright green.

What about the yellowing of green apple leaves? what about the yellowing of hydroponic green apple leaves?

Causes of yellowing of hydroponic green pineapple leaves

Environmental abrupt change

Generally, the newly bought green apple has an adaptation period of about 1 month to the new environment, and the bottom yellow leaves are normal, but remember: yellow or dead leaves should not be peeled off directly and should be cut off from the middle of the petiole so as to avoid direct peeling causing too much water loss and increasing the wound; as a result, the upper leaves will still be yellow.

Discomfort of light and temperature

Green pineapple likes high temperature, humid, semi-overcast environment, can not bear cold, and the overwintering temperature is not lower than 10 ℃. It is sensitive to temperature, avoid direct sunlight in summer, and it is easy for leaves to turn yellow and fall off under strong light. It can grow well under the bright scattered light indoors in winter, and has a higher requirement for water during the growth period.

The water quality is poor

Hydroponic green pineapple may also be due to bacteria in the water, if it is tap water culture, it may be due to the high content of bleach in the water. Green pineapple itself is not resistant to low temperature, low temperature for a long time and large water will lead to rotten roots, resulting in insufficient water supply to the roots, and finally the root leaves begin to turn yellow, and the top leaves lose their luster.

The solution to the yellowing of green apple leaves in hydroponic culture

There is plenty of sunshine

It should be placed where the scattered light is sufficient, and water is often sprayed to the leaf surface during the growth period. Spraying 0.2% potassium dihydrogen phosphate can restore the stripes on the leaf surface. Use a large culture container as much as possible, and oxygen can be added to the water if possible.

Fertilizer application

Spraying 1% urea is OK, any creature has a life cycle, it may be old and let nature take its course. Only when it is withered and yellow will it send new leaves. There is no need to worry.

Change water frequently

Then there is the change of water once a week in hydroponics. If you have the conditions to put some Maifan stone or small stone, it will effectively reduce the occurrence of yellow leaves. Rinse the roots well when changing water, and cut off the diseased roots. Don't put too much water, just don't have a root. When raising water, it is recommended to wrap the roots, soil and sawdust of green pineapple with cloth and put them in water.
