Why don t the longevity flowers at home grow very long, and even show signs of yellowing?

If it does not bloom, it is likely that your longevity flowers lack some nutrients, do not give them some fertilizer in time, and there is a certain lack of water and soil, so that the longevity flowers can not be developed normally, and they should be properly applied with some phosphorus and nitrogen fertilizers, which can well alleviate the yellowing state of flowers.

Maybe it's because of the insects, I suggest that you can thin the flowers and fruits and cut off the bad leaves. Apply some potassium permanganate water.

In general, it is likely that there is not enough sunlight and ventilation, and if you water too much, it will turn yellow.

The phenomenon of discoloration is mainly related to temperature, light and variety, and the color of the early, middle and late flowers of its rapid flowering will be slightly different, at this time there is no need to worry too much, as long as the plant is in a healthy state, if there are withered flowers, it needs to be cut off in time.

1. Temperature influence

If the temperature is a little higher, its flower color will be darker, and if the temperature is lower, its color will be lighter, as long as the plant is in a healthy state, you don't need to worry too much.

2. Light influence

Longevity flowers appear discoloration, there may be the influence of light, if the light is stronger, its color will be darker, if the light is weak, its color will become lighter, in its flowering period we had better let it have an appropriate amount of scattered light irradiation, so that its flowers will be more beautiful.

3. Variety influence

There are some longevity varieties that are artificially cultivated, the shape of such varieties is not stable enough, in the process of flowering, the color will gradually change, we only need to cut off some of the flowers to wither in time.

The reasons for the discoloration of longevity flowers may be related to temperature changes, light intensity, and variety differences. The flowering period of this plant is very long, when the temperature is high, the color of the ant will be slightly deepened, and when the temperature is low, it will become lighter accordingly, when the light is strong, it will become darker, and when the light is weak, it will become lighter, and some artificially cultivated varieties are not stable and mature enough, and there will be discoloration.

1. Temperature change

The color of the longevity flower may be due to a change in temperature. The flowering period of longevity flowers is much longer than that of ordinary flowers, so it is more obviously affected by temperature, the color of the flowers will become darker when the temperature is high, and the corresponding will become lighter when the temperature is low, as long as the plant is not abnormal, there is no need to worry.

2. Light intensity

The color change of longevity flowers may also be due to the influence of light, the intensity of light can also affect the color of the flowers to some extent, the light intensity is high, the pigment accumulation of flowers becomes darker, and the pigment accumulation is less and becomes lighter when the intensity is low, we had better use scattered light irradiation, so that the color of the flowers is more stable.

3. Variety differences

Some varieties of longevity flowers are not naturally reproduced, but artificially cultivated new varieties, these new varieties because the breeding generation is not enough, the traits of the varieties are not very stable, so in the process of flowering will gradually change, this is a normal phenomenon, we do not need too much manual intervention.

4. Precautions

Although the color change of longevity flowers is not a negative effect, if we find that the flowers become wilted, yellow or black, it is not a normal phenomenon, it is very likely that the plant is infected with imitation resistant bacteria, resulting in the flower is infected, we should cut off the diseased flowers and leaves in time, spray drugs to control pests and diseases.

Hello, this is a very normal situation, and there are many factors that affect the color, mainly the two elements of light and variety, when the light is weak or too strong, the color of longevity flowers will become lighter. There are also some varieties of longevity flowers with unstable flower color, and the flower color will also change in the front, middle and back stages of the flowering period, and the color of this change depends on the specific variety. Relatively speaking, the varieties with more stable flower colors are mostly single-petal varieties and some more common double-petaled varieties, and some new varieties are not stable enough, so I will not give examples here.

The most important thing is that the color change of longevity flowers does not affect the health of the plant, so as long as the plant is healthy, there is no need to worry, for the flowers that are about to wither, it is necessary to reduce the flower pavilion in time, so that there is still a chance to send new branches to continue flowering, and the old flowers are useless to stay on the plant, because longevity flowers rarely produce seeds, so losing them as soon as possible helps to retain nutrients.

Overwatering or lack of water: Kalancho flowers need to be kept at the right amount of humidity, but both overwatering or lack of water can cause the leaves to turn yellow. If the soil is too wet or too dry, it may cause root rot or atrophy.

The solution is to check the soil moisture before watering and make sure the top layer of the soil is dry before watering.

Lack of fertilizer: If the longevity flowers do not receive enough nutrients, the leaves will turn yellow. The solution is to fertilize the kalanchos once a month and use a fertilizer suitable for them to ensure they get enough nutrients.

Insufficient or too much light: Longevity flowers need moderate sun exposure, and if there is not enough or too much sunlight, the leaves will turn yellow. If the kalanthus is indoors, it should be placed in a well-lit location, such as a balcony or next to a window.

Pests and diseases: Longevity flowers can be affected by pests and diseases, such as leaf mites and whiteflies. These pests can cause the leaves to turn yellow and wither. The solution is to treat the leaves and soil with pesticides, make sure they are dry, and make sure that the air circulates well inside the pot.

Avoid exposure to the sun and move it to a cool place. Watering too much root rot can also cause the leaves to turn yellow. Exposure to cold winds can also cause yellow leaves. The suitable temperature for growth is 15 to 25

Gently pull it out and see if the roots are not, if.

If not, there is a lack of fertilizer.

Kalancho flowers are very leathery, but they also have yellow leaves, and according to personal experience, they basically occur from flowering to the end of flowering.

The reason for the analysis is that the long-lived flowering is very large and has a high consumption of nutrients, while for the plant itself, the flower is the most important part of the plant, so it needs to absorb nutrients from the leaves.

It is necessary to replenish a large amount of nutrients before flowering, and you can use potassium dihydrogen phosphate solution to water the flowers, and the concentration can be appropriately higher.

The best time to supplement fertilizer is when the flower bones appear, and now you can make up some appropriately, but the bottom leaves are estimated to fall off and cannot be avoided.

Now I will talk about the experience of breeding longevity flowers in recent years, I hope to help you:

1. The plant likes sunlight, do not place it in a shady place, it is easy to cause yellowing of the leaf surface and a large area of leaf shedding 2 like drought, it is better to dry the soil in the pot, watering too frequently, it is very easy to appear foliar yellowing and rotten leaves 3 Cold tolerance is poor, and the indoor temperature should not be lower than 15 degrees in winter, otherwise the whole pot of plants will be frozen.

Is it the reason for too much watering, longevity try to water as little as possible, wait for the soil to dry before watering, and bask in the sun more. But it doesn't matter from the picture, a little yellow is not a big problem.

1. Caused by too much watering:

Due to the yellowing of the leaves of longevity flowers caused by long-term watering, we all know that longevity flowers generally do not need to be watered too much, too much watering will make paper, young leaves do not have rigid rules, and old leaves do not change much. The roots are relatively small, and if there is too much water, it will affect the respiration of the roots of the longevity flower, so that it can absorb nutrients.

Solution: Watering should be controlled, as long as you water thoroughly every 3-4 days, keep the potting soil slightly moist. What to do if the leaves of longevity flowers are yellow, control watering in winter when the temperature is low and in the rainy season to avoid root rot.

In the peak growing season, thin compound liquid fertilizer can be applied every 2-3 weeks.

2. Due to drought:

If it is because the owner has no time to manage, the drought will also cause the leaves of the longevity flower to turn yellow, and under normal circumstances, if there is a lack of water, the old leaves will wither and fall off from the bottom up, and the growth of new leaves will be normal.

Solution: Be diligent in management, understand the growth cycle of longevity flowers, and the watering habits of each period. Increase the amount and frequency of watering appropriately.

3. Caused by fertilization:

If the fertilization is too much or the concentration is too large, the top of the new leaves will appear brown, the old leaves will appear dry and scorched and yellow, and the leaves of longevity flowers will be yellow.

Solution: Fertilization should be controlled. If necessary, you can take out a detector to check the moisture situation. Find out the moisture status of kalancho flowers.

Longevity flowers like fertilizer, and can be applied once after flowering with nitrogen-based liquid fertilizer to promote their rejuvenation. The rest of the time in addition to the summer stop, can only apply nitrogen, phosphorus and potassium compound fertilizer, do not make fertilizer on the leaves, otherwise the leaves are perishable, 4, too strong light or too little light caused

Kalancho flowers like full sun, but we know that too much light at noon in summer can also cause the leaves to burn and turn yellow.

The chlorophyll in the leaves of longevity flowers is reduced due to the lack of light for a long time, so that the green color of the leaves gradually disappears, showing albinism.

Solution: It is advisable to shade a little outside at noon in midsummer, and place it in a sunny place for the rest of the time, and you must be able to see direct light for at least 4 hours a day to grow robustly. What to do if the leaves of longevity flowers are yellow, although they can also grow in the semi-shade, but the stems are thin and the leaves are thin and the flowers are less and the color is light, if the shade is easy to fall off the leaves without flowers, the most suitable temperature for the growth of longevity flowers is 15 to 25, and they can bloom in December.

5. Damp and hot yellow:

Longevity flowers are not resistant to high temperatures, and yellowing is caused by hot summer, poor ventilation and improper shade. This phenomenon occurs in a hot and humid environment, and attention should be paid to ventilation and cooling, and the potting soil should not be overheated.

6. Low temperature yellow:

In the cold winter, if the indoor temperature is low, some flowers that are afraid of cold will also turn yellow and fall off. In addition, flowers that are damaged by pests and diseases can also cause yellow leaves to fall off. What to do if the leaves of longevity flowers are yellow, if a few leaves in the lower part of the plant turn yellow and fall off, it is a normal phenomenon.

The appearance of yellow leaves, depending on the characteristics of its occurrence, has the following situations:

One is water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;

The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;

The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;

Fourth, hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning;

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.
