Why do desert roses turn yellow and lose their leaves after flowering?

Desert roses turn yellow and lose their leaves after flowering, possibly due to low temperatures, which is normal to reduce water evaporation and nutrient output in winter.

If you water too much during flowering, it will affect the fall of leaves, although there is nothing wrong with the flowers, but it will also speed up the withering, then the flowers will wither, and the leaves will naturally begin to yellow and fall.

1. Insufficient nutrients after flowering.

Flower friends who often breed plants will know that plants need to supplement nutrients before flowering, and they are afraid that they will not be able to bloom during flowering because of insufficient nutrients.

2. Overwatering.

If you water too much during flowering, it will affect the fall of leaves, although there is no problem with the flowers, but it will also speed up the speed of withering, the flowers will wither, the leaves will naturally begin to yellow and fall, it is recommended to check the root system first, if there is no rotten roots, it is still relatively easy to recover from breeding.

3. Normal phenomenon.

When the new leaves of the plant begin to grow, you will find that the original old leaves begin to yellow and fall, if the subject confirms that there is no lack of nutrients and no rotten roots, you don't need to care about it, and it will be restored later.

After the desert rose blooms, the leaves turn yellow and lose their leaves one after another, and the main reasons are as follows: First, there is not enough light. The subject's desert rose is placed on the indoor balcony for maintenance, which is completely contrary to its growth habits, it is a very light-loving summer succulent, but also resistant to high temperature and heat, so in addition to winter, other times must be placed in the outdoor sunny environment for maintenance, if the maintenance environment is too sheltery, it will affect its normal photosynthesis, and then it will naturally appear yellowing and falling off the phenomenon.

Treatment: Move the desert rose to the open air in time to maintain, and at the same time give it enough light, and avoid rain, after a period of time it will return to normal and grow into a leafy form. Moreover, the desert rose will grow better in the summer, and it will also produce more flowers.

Second, improper watering. Desert rose because the stalk stores a lot of water, so it is very drought tolerant, in the usual maintenance if the potting soil is not dry, do not water it, otherwise the potting soil will be moist for a long time will lead to its rotten roots and rotten stems, etc., and the initial reaction is that the leaves are yellow and fall off.

Treatment: Check if the stalks of the desert rose are soft, if not, move to a sunny and well-ventilated place to maintain, and continue to observe, as long as it does not continue to yellow and lose leaves. If the desert rose stalks are soft, or put them in a ventilated place and the situation is still not improving, then quickly remove the pot to check the root system, and if there is a problem with the root system, repair the roots in time and soak carbendazim for disinfection, and then dry the roots for about 5-7 days and then take them to change the soil and replant.

Third, it is infested by insects. If the desert rose is kept in a poorly ventilated environment, it is easy to breed scale insects and red spiders, and if the insect infestation is severe, it will also cause its leaves to turn yellow and fall off. Solution:

Check the stalks and the back of the leaves of the desert rose in time to see if there are chains dressed with scale hut insects and red spider activities, if there is one, spray immediately to kill, the former can use cocoon and chlorpyrifos, etc., while the latter can use avermectin, dicofol and pyridoxin, etc., and when the insects are eliminated, the desert rose will naturally return to normal.

There are four reasons for the loss of yellow leaves of desert roses: frost damage, root rot, infection with pests and diseases, and improper environment.

1. Suffer from frost damage: Desert roses like warmth, not tolerant to cold, and will be dormant when the temperature is low in winter, and even frostbite plants, which will naturally cause yellow leaves and leaf loss. In this case, it is necessary to raise the temperature and move the desert rose to a warm place indoors to maintain the temperature above 10 degrees.

2. Root rot: Root rot is the main reason for the yellow leaves and leaf loss of desert roses, and the reason for root rot is likely to be too frequent watering, too much and too thick fertilization, etc., and the roots cannot be absorbed and transformed, causing root rot, yellowing of plant leaves, falling, and even plant death. If it is found that there is a rotten root, it should be dealt with in time to avoid a more serious situation.

The desert roses are depotted in time, the rotten roots are removed, the roots are disinfected and sterilized, and then replanted.

3. Infection with pests and diseases: If the growth environment is not properly maintained, it may breed pathogens, which may lead to infection of pests and diseases, and the leaves will turn yellow and fall, which will have a greater impact on the growth of plants. Usually pay attention to the cultivation method, to prevent the appearance of pests and diseases, once the pests and diseases are found, cut off the diseased branches and leaves in time, and spray the corresponding pesticides.

4. Improper environment: During the maintenance period, insufficient light in the growth environment and poor ventilation will also lead to yellow leaves and falling. You can increase the amount of light, keep it in a sunny place, and maintain good ventilation.

Desert Rose Introduction

Desert rose, in fact, it is not a rose that grows in desert areas, and it has no close relationship or resemblance to roses. Also known as: Tianbao flower, oleanderaceae, which is a plant of the oleander family.

Temporo is a succulent, also known as a succulent plant. Succulent shrubs or small trees, up to ; The trunk is swollen.

Leaves simple, alternate, clustered branches, obovate to elliptic, up to 15 cm long, entire, apex obtuse with short point, fleshy, nearly sessile. It likes high temperature, dry and sunny environment, is resistant to scorching heat, not cold-tolerant, and is named desert rose because of its proximity to the desert and red as roses; Native to Kenya and Tanzania in Africa, the flowers are beautiful when they are in full bloom and are often cultivated for ornamentation.

The yellowing of desert rose leaves is due to: lack of water, lack of fertilizer, weak light, repotting, etc.

1. Lack of water

One of the main reasons for the yellowing and loss of desert rose leaves is that they have not been watered for a long time, that is, due to lack of water. The principle of watering a desert rose is to water it thoroughly in a timely manner when the potting soil is dry. I don't know when the potting soil is dry, you can pinch off his roots, a little soft, proof of lack of water, just water it in time.

2. Lack of fertilizer

In one of the causes of its leaf shedding is the lack of fertilizer, there are so many potting soils, there are no nutrients in it, and it can't get nutrients, and the leaves will turn yellow and fall off. Therefore, it is necessary to fertilize it, and after fertilization, the roots will absorb nutrients, and gradually it will shed its leaves.

3. Weak light

There is also a situation that causes the leaves to fall because there is no light, that is, the light is weak, but if this situation occurs, the color of his leaves will be light. Moreover, the long leaves are thin, and the leaf spacing will be relatively long. If this is the case, it can be clearly distinguished, and it can be mitigated by adding light appropriately.

4. Change the pot

If it's a freshly bought desert rose, it's the kind of bare-rooted, or it's repotted after you bought it. It will hurt the root system, and the root system has not yet grown new roots, and its nutrients will be insufficient, which will lead to the yellowing and falling off of its leaves.

Desert Rose Growth Habits:

It likes high temperature, arid, sunny climate environment, likes calcium-rich, loose and breathable, well-drained sandy loam soil, does not tolerate shade, avoids waterlogging, avoids thick fertilizer and raw fertilizer, is afraid of cold, and grows at a suitable temperature of 25 to 30.

In summer, it can be placed outdoors in a sunny place, without shading, and fully watered to keep the soil moist, but not waterlogged. In winter, watering should be moderate, and the overwintering temperature should be maintained above 10 to make the leaves dormant. During cultivation, organic fertilizer is applied 2 to 3 times a year as appropriate.

Propagation can be selected in the summer about 10 cm of 1 to 2 years of branches to intercept, after the cut is slightly dry, cuttings in the sand bed, 3 to 4 weeks can take root. It can also be propagated in the summer with the high-altitude strip method. If seeds can be collected, they can also be propagated by sowing.

The yellowing of the leaves of <> desert roses is caused by improper light, watering, temperature, and fertilization. Keep in full sunlight every day to promote the growth of branches and leaves. Each watering to keep the potting soil slightly moist environment, the most suitable growth temperature is stable between 20-28 degrees, the growth period is applied once every half month, and the phosphorus-containing fertilizer is applied once before wintering.

First, the light is not appropriate to guide the grandson.

Insufficient light or exposure to the sun causes the leaves of the desert rose to turn yellow, because it likes to grow in a more sunny environment, so it is necessary to carry out proper sun exposure, pay attention to the summer when the light is stronger, it is necessary to properly shade to prevent the occurrence of sun exposure.

2. Caused by improper watering.

Desert roses prefer to grow in a humid environment, and long-term watering too much or too little will cause the leaves to turn yellow. Therefore, you can water more during the growth period, but there should be no standing water. In autumn and winter, it is gradually cold, so you can control the amount of watering and keep the potting soil slightly moist.

3. Improper temperature.

The temperature is too high or too low to cause the desert rose leaves to turn yellow, because it likes to grow in a relatively warm environment, the most suitable growth temperature is between 20-28 degrees, so in the summer breeding time when the temperature exceeds 35 degrees, it is necessary to do a good job of cooling measures. In winter, when the temperature is low, take measures to keep warm and keep the plants warm, so as not to damage the plants by frost.

Fourth, caused by improper fertilization.

Long-term fertilization is too good or severely damaged, which will cause the leaves of the desert rose to turn yellow. Therefore, it is necessary to apply fertilizer regularly and appropriately, during the growth period, you can apply phosphorus and potassium fertilizer every half month, apply phosphorus-containing fertilizer once before wintering, and stop fertilizing or not fertilizing in winter.

Causes of yellowing of desert rose leaves: too low temperature, too much watering, not enough light.

1. The temperature is too low

Desert rose is native to Africa, is a plant that likes high temperature very much, generally suitable for its growth of the temperature between 25 degrees and 30 degrees, it is more afraid of cold, when the temperature is lower than 10 degrees when the growth will be affected, at this time there will be a situation where the leaves will yellow and fall off, so we should maintain a good temperature when maintaining desert roses in winter to avoid freezing.

2. Overwatering.

Desert roses like a dry growth environment, very afraid of waterlogging, during the maintenance period to keep the potting soil moist, can not be watered too often, otherwise it is easy to cause potting soil waterlogging, which will lead to the roots of the desert rose can not be better contact with the air and rot, and the roots rot, the leaves will appear yellow.

3. Insufficient light

Desert roses like a sunny growth environment, we must maintain sufficient light when maintaining desert roses, even if the strong light in summer does not need shade, if the light is insufficient, then the leaves of the desert rose can not better photosynthesize, which will lead to a decrease in the chlorophyll content in the leaves, and the leaves will turn yellow.

Cultivation method of desert roses

1. Suitable soil

Desert rose has strict requirements for soil, grows faster in loose, fertile, and slightly acidic soil with good drainage, and generally selects cinder, perlite, vermiculite, and peaty soil in accordance with the ratio of 5:1:1:3 to prepare soil.

2. Sufficient light

Desert rose loves warm sunlight, the daily light duration is best not less than 4 hours, insufficient light, will cause its leaves to wilt and lose luster, affecting the overall appearance, summer light is stronger, can be moderately shaded, can be moved to the outside in the morning and evening to receive light.

3. Water regularly

Desert rose belongs to tropical plants, rhizomes are rich in water substances, so the demand for water is not large, and too frequent watering should be avoided during the growth process.

Desert rose yellow leaf cause.

1. Overwatering.

Desert roses like a dry environment, very drought tolerant, avoid water and moisture, so you must be careful when watering, don't be too diligent too much, otherwise it may lead to soil waterlogging, resulting in yellowing and falling off of leaves.

2. The temperature is low.

Desert roses go dormant during the low temperature of winter, and the leaves turn yellow and dry up or even fall off, all in order to reduce the consumption of nutrients, which is a self-protection mechanism and do not have to worry.

3. Insufficient light

The desert rose prefers a sunny environment, which is helpful for it to bloom, even during the dormant period, it needs to be sunned, and if it is left in a cool and dark place for a long time, the desert rose leaves will turn yellow and fall off.

What to do if the desert rose leaves are dropped.

1. Once the desert rose loses its leaves, you can observe whether its roots are softened, because if the roots are rotten, it is caused by excessive watering, at this time, you should stop watering in time, place it in an outdoor ventilated place, keep the soil dry, and choose sandy soil with good drainage.

2. If the yellow leaves of the desert rose are caused by too low temperature, you can move it indoors, maintain a suitable temperature, and avoid frost damage caused by low temperature.

Prevent the yellow leaves of desert roses from falling off.

Desert roses like light, every day to bask in the sun, not less than 4 hours, the scorching sun in the summer afternoon in time, the rhizome of the desert rose contains more water, drought tolerance, watering and other soil dry watering, to avoid waterlogging, in addition, the growth stage also needs to be topdressed, with diluted liquid fertilizer on the line, once a month.
