Why potted desert roses kept at home are easy to yellow

Improper watering can lead to yellow leaves, too much water or excessive drought can also lead to yellow leaves in desert roses, and if infected with pests and diseases, it will definitely cause the leaves of desert roses to turn yellow.

If the leaves of the desert rose are spread from the petiole to the tip of the leaf, it is due to lack of light and excessive drought of the soil, and too much watering will also lead to yellow leaves!

There are many reasons for the yellowing of desert rose leaves, the first point is that the water storage capacity of the desert rose plant is not particularly large, if the water is overwatered, it is easy to turn yellow, and the second situation is that the root rot disease occurs. The third case should be the burning of seedlings caused by excess fertility.

Reason: Desert rose is very drought tolerant, if it is often watered or poorly ventilated and often exposed to rain, it will definitely have yellow leaves, and it may rot in serious cases.

Solution: Change the current breeding environment according to its growth characteristics, and move it indoors in time if it is often placed outdoors by rain.

Reason: Desert roses are very drought tolerant, and if they are watered frequently or frequently, it can easily lead to root rot and yellowing of leaves.

Solution: First of all, control the amount of watering, and the frequency of watering should not be too frequent, if the roots have been rotten, you can cut off the rotten roots.

Reason: If the fertilizer is applied excessively, the root cells will also die easily, which will cause the leaves to turn yellow.

Solution: Fertilize reasonably, don't fertilize too much or too often.

Reason: If the ventilation is not good, it will also cause the leaves to turn yellow, and if it is serious, it will also die.

Solution: Move it to a well-ventilated location, or open a window often, or place it on a window or balcony.

Reason: The roots of the desert rose also need to breathe, if the soil is relatively sticky and not breathable, it will cause the roots to rot, and naturally will not be unable to absorb nutrients, and yellow leaves will follow.

Solution: You can replace the soil with better air permeability for it, or you can re-loosen the soil.

Desert rose is often classified as a succulent, its stem is larger, can survive in an arid environment, desert rose is not tolerant of humid environment, so if you water too much, or let it rain too much in the rainy season, coupled with air can not circulate, light is weak, it will cause the desert rose to appear yellowing of the leaves, if serious will also lead to the whole plant of desert rose rot and death.

Solution We need to understand its growth habits in daily maintenance, and maintain it reasonably according to the condition to prevent it from happening.

Excessive watering is also an important reason for the yellowing of the leaves, desert roses are not resistant to moisture, so the amount of watering should not be too much, otherwise it will cause water accumulation in the roots, resulting in rotten roots, which will make the leaves yellow and fall off, and even wilt.

Solution Cut off the rotten roots, and pay attention to the reasonable watering of the desert rose, do not make too much watering, watering less, desert rose is drought tolerant, so it does not need too much water.

The winter climate is cold, the temperature is low, the desert rose enters the dormant period at this time, it will have the situation of drying up and losing leaves, in order to reduce the evaporation of its own water, self-protection, at this time the fertilization can not be too much, not too thick, otherwise it will lead to yellowing and even death of the leaves.

Solution Maintain a suitable temperature, the amount of fertilizer is reasonable, not too much, it is best to put desert roses in a greenhouse for cultivation.

Desert roses love temperature and prefer a ventilated growing environment, and poor ventilation will cause rotten roots and yellow leaves.

Solution Place the desert rose potted plants in an indoor ventilated position, which is conducive to balconies, window sills and other locations for cultivation.

Pests and diseases are also an important cause of the yellowing of desert rose leaves, and its main pests and diseases are scale insects, which will cause the whole plant to fall off and grow sluggishly until death.

Solution If scale insects are found, they should be sprayed with 2000 times of 40% dimethoate emulsifiable concentrate in time for spraying and control.

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.

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.

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.

Environmental changes. Desert roses are often classified as succulents by us. They have large stems and can survive in arid environments.

Desert roses do not tolerate humid environments. So, if there is too much watering, or if there is too much rain during the rainy season, the air is not circulated, and the light is weak, the leaves of the desert rose will turn yellow. In severe cases, the entire desert rose will rot and die.

Solution. We need to understand its growth habits in daily maintenance, and carry out reasonable maintenance according to the condition to prevent problems before they occur.

Overwatering. Overwatering is also a great cause of yellowing of the leaves. Desert roses do not tolerate moisture, so do not overwater them, as this will cause water to accumulate in the roots, causing root rot, causing the leaves to turn yellow, fall off, and even wilt.

Solution. Cut off the rotten roots, paying attention to the proper watering of the desert roses. Do not water too much or too little. Desert roses are drought resistant, so they don't need much water.

Fertilization at low temperatures. Winters are cold and the temperatures are low. At this time, the desert rose enters the dormant period, and it will dry up and lose its leaves to reduce the evaporation of its own water and protect itself. At this time, the fertilizer should not be too much or too thick, otherwise it will cause its leaves to turn yellow or even die.

Solution. Maintain the appropriate temperature, apply a reasonable amount of fertilizer, and do not overdo it. Desert roses are best cultivated in greenhouses.

Poor ventilation. Desert roses prefer to grow in a warm and airy environment. Poor ventilation can lead to rotten roots and yellow leaves.

Solution. Placing potted desert roses in a ventilated place indoors is conducive to propagation on balconies, windowsills, etc.

Pest. Pests and diseases are also an important cause of the yellow leaves of desert roses. Its main pests and diseases are scale insects, which will cause the whole plant to fall off, stagnate or even die in severe cases.

Solution. If scale insects are found, they should be sprayed with 40% dimethoate EC2000 times solution in time to kill.

Prefer high temperature, arid, sunny climate environment, like calcium-rich, loose and breathable, well-drained sandy loam, not tolerant to shade, avoid waterlogging, avoid thick fertilizer and raw fertilizer, afraid of cold, growth temperature 25-30.

Sunshine: Good sunshine helps desert roses bloom. In addition to the vigorous growth period, the desert rose still needs plenty of sunlight to overwinter even during the dormant period.

Desert roses like to grow in a high-temperature and ventilated environment, and in the summer of the south, that is, the growth period of the desert rose, the average temperature is around 30, making it very suitable for growing in the south; In winter, desert roses are indoors for cultivation due to their poor cold tolerance.

Watering: Desert roses should be grown in a humid environment. Even during the growing period, there should be no excessive water, and before each watering, make sure that the surface of the potting soil is completely dry.

Do not water the plant during its dormant period, as this will only make the plant more susceptible to cold damage and wilting.

Fertilization: The spring and summer rainy seasons are the growing season for desert roses, so a little fertilizer should be added at this time to adequately the nutrients consumed during their growth. However, due to the fast and slow growth rate of desert roses, it is better to use slow-acting fertilizers, such as well-rotted compost.

As for autumn and winter, it is the dormant period of the desert rose, its growth is very slow or even stops, therefore, it is important not to fertilize during this time.
