Du Juan, what if the leaves turn yellow?
The yellowing of azalea leaves may be caused by the following reasons, and corresponding solutions can be taken according to different reasons: ** I. Conservation issues ** 1. ** In terms of moisture ** - If you forget to water it daily, the lack of water in the cuckoo will cause the leaves to turn yellow. It is necessary to replenish water in time and keep the soil moist during the growth period. - Azalea liked loose and moist soil. If it was watered too much and too frequently, it would cause the soil to accumulate water, causing the roots to rot and the leaves to turn yellow. At this time, he had to quickly loosen the soil for the cuckoo to promote the water to evaporate. He just needed to keep the soil slightly wet every day. 2. ** Illumination ** - Cuckoos liked cool environments with scattered light. The leaves would turn yellow if they were not exposed to light for a long time or if the light was too strong. The flower pot needed to be moved to a place where there was scattered light in time. It should be properly shielded in the summer when there was strong light. 3. ** In terms of temperature ** - Raising cuckoos required a warm and comfortable environment. If the temperature was low or there was a cold wind blowing, the cuckoo would easily suffer from frost damage, causing its leaves to turn yellow. It should be provided with a suitable temperature of 15 - 25 ° C for growth. In winter, the temperature should be above 10 ° C to safely pass the winter. ** 2. Soil problem ** 1. ** Soil pH-value ** - Azalea flowers like acidic soil, usually with a pH between 4.5 and 6. If the soil is too salty, the leaves of the azalea may turn yellow. One could use an acidic soil conditioner or soil specially made for azalea flowers to adjust the ph of the soil. For example, one could use a mixture of 1:1000 of Ferrous Sulphate and water. After the mixture was dissolved, it could be directly poured into the pot soil. After about 20 minutes, it could be watered with clear water. It could not only supplement iron but also make the soil acidic. Daily maintenance, watering some vermicelli water every month, or watering some vinegar can also improve the soil's acidic nature. 2. ** Soil fertility and texture ** - The soil of the azalea that had been cultivated for a long time might become alkalized, hardened, malnourished, and lack of iron, causing the leaves to turn yellow. Therefore, when planting cuckoos in pots, it was necessary to use loose, fertile, and acidic soil rich in organic matter. In the later stages of maintenance, the soil should be changed once every 2 - 3 years to promote growth. ** 3. The problem of fertilisation ** 1. ** Lacking fat ** - Azalea flowers had high requirements for nutrients. If the soil lacked the necessary nutrients, such as nitrogen, phosphorus, and potassium, the leaves would easily turn yellow. For example, the blooming of azalea consumed a lot of nutrients, and its growth also consumed nutrients. Without fertilizer, the soil would not have nutrients, and the leaves under it would gradually turn yellow. The fertilizer should be supplemented in time. For example, the application of monobium potassium orthonate once a month to promote flowering, the application of multi-element compound fertilizer in spring to promote growth, and the application of fertilizer should be stopped when the temperature is high in summer and low in winter. 2. ** Over-fertilized ** - Although the azalea needed the right amount of fertilizer, excessive fertilizer could also cause damage to it, causing the leaves to yellow. If the fertilizer concentration was too high, it would cause the seedlings to burn their roots and the leaves to turn yellow. They should irrigate the roots with water in time to dilute the fertilizer solution, and place the azalea in a place with ventilation to promote the evaporating process. ** 4. Pests and diseases ** - Some pests and diseases could also cause the leaves of the azalea to turn yellow, such as leaf mites, aphids, and insects. Carefully observe the leaves and plants. If you find any abnormalities, you can take corresponding measures to prevent and control them. For example, after discovering the invasion of germs and insects, you should spray targeted chemicals in time to prevent and control them. Once a week, spraying three times in a row can be effective. ** 5. Special circumstances ** 1. ** New saplings purchased ** - It was normal for the newly bought azalea to have yellowing leaves due to changes in the environment. As long as the cuckoo was placed in a semi-shady and well-vented place, it would be able to grow normally in about a week. 2. ** In terms of trimming ** - After finding yellow leaves, they should trim the cuckoo in time, cutting short the yellow leaves, sick branches, weak branches, and overgrown branches to save nutrients and make the branches reasonably distributed.

What should I do if the leaves of Du Juan's flowers turn yellow and charred?
The yellowing and charring of the azalea leaves may be caused by the following reasons, and corresponding solutions can be taken according to different reasons: 1. ** Conservation issues ** - ** Insufficient or excessive water **: Azalea has small roots. Water shortage, drought, or rotten roots will cause the leaves to turn yellow and scorched. Daily watering should be done in a timely and adequate manner, but it should be done to prevent water accumulation and root rot. During the growth period, the soil should be moist but not wet. In winter, the soil should be slightly dry. When the environment is dry, increasing the air humidity can improve it. If you water too much, make sure the soil is well drained to avoid water accumulation; if you water too little, replenish water in time. - [Light Discomfort: Azalea flowers prefer soft scattering light environments.] If the light was too strong, it would cause the leaves to turn yellow and the edges to dry up. Long-term lack of light was also detrimental to the growth of the plant. It was easy to cause the branches to grow long, the leaves to be thin, the leaves to turn yellow, and the leaves to fall. It could even cause the phenomenon of no flowers or few flowers. The sunlight in spring and autumn was mild, so the potted cuckoo could receive scattered light. In summer, the light intensity was high, so it was necessary to cover the shade and block the sun. In winter, the light was obviously weakened, so it could be placed under the sun to be sun-dried, which was conducive to the formation of photosynthesis and reduce the phenomenon of yellow leaves. - [Uncomfortable temperature: If the temperature is too low or the cold wind blows on the azalea, it will cause the yellow leaves to wither.] The surrounding temperature should be controlled between 15 - 25 ° C. In winter, move indoors as soon as possible, control the room temperature above 10 ° C, and keep it in a sunny place. 2. ** Soil problem ** - ** Soil is too salty or hardened **: Azalea flowers like acidic soil, usually between 4.5 and 6. If the soil was too salty or watered all year round, it would cause the soil to harden, and the plants would not grow well and the leaves would turn yellow and scorched. During the growth period, it is advisable to irrigate the soil with water or vinegar once a month, or adjust the soil to be slightly acidic with dilute solution of iron and sulfuric acid; change the soil once every two years, and purchase slightly acidic sandy soil rich in humus, loose and airy, so as to maintain fertility. 3. ** Problems with fertilizers ** - ** lack of fertilizer **: Azalea flowers have high requirements for nutrients. If the soil lacks the necessary nutrients, such as nitrogen, phosphorus, and potassium, the leaves will easily turn yellow and scorched. You can use an appropriate amount of azalea fertilizer and apply it according to the product instructions. - ** Too high fertilizer concentration **: The roots of the cuckoo are relatively thin, and its absorption ability is not strong. If the fertilizer concentration is too high, it will cause the roots to burn and the seedlings to burn, causing the leaves to turn yellow and scorched. Daily fertilizer application should pay attention to thin fertilizer and frequent application. Once thick fertilizer is used, it should be watered with large water in time to dilute the fertilizer solution, and maintained in a well-vented place to promote soil drying; If the situation is serious, it should be turned over in time to remove the plant from the pot, trim the rotten root system, and then use 0.2% potassium Permanganate solution to disinfect the root system. After the root system is dried, it should be replaced with cultivation soil and planted in the pot, and then placed in a cool and well-vented place for maintenance. 4. ** Pests and diseases **: Some pests and diseases may also cause the azalea leaves to turn yellow and scorched, such as leaf mites, aphids, and insects. Carefully observe the leaves and plants. If you find any abnormalities, you can take corresponding measures to prevent them. Open the windows frequently, raise the cuckoo in a place with good ventilation, and spray it with medicine regularly to effectively kill aphids, red spiders, scale insects, and so on. Once pests and diseases were discovered, targeted drugs should be used once a week for three consecutive times. 5. ** Irritated **: The leaves of the cuckoo are fragile, improper use of daily pesticide, residual dosage, sudden changes in the environment, and sudden cold and heat can cause the leaves of the cuckoo to turn yellow and scorched. Maintain the azalea in a warm and comfortable environment to maintain a gentle and constant temperature, promote ventilation, and increase the humidity of the air. In addition, if the azalea special nutrient solution was used, it could be used according to the product instructions. For example, some nutrient solutions did not need to be diluted and could be sprayed directly on the leaves or roots. It could be used in the morning or evening and sprayed once every 10 days or so. It could improve the condition of yellow leaves, wilting, bud dropping, and no flowering. If you are unable to determine the exact cause of the problem, it is recommended to consult a gardener or bring the photo to the flower shop for help.

Du Juan, what if the leaves are dry?
The withered leaves of the cuckoo could be caused by many factors, and corresponding measures could be taken according to different reasons. If the lighting conditions are not appropriate, cuckoos like half shade or scattered light, should avoid direct sunlight or excessive shade. In the summer, it should be shielded from the sun. In winter, it can be moved indoors to a warm and scattered place for maintenance. If it was a problem with water, the azalea's hair roots would react to water. Long-term water shortage would dry up the hair roots, so they had to be watered in time when the soil was slightly dry. However, overwatering would cause the roots to rot due to lack of oxygen, so it was only necessary to water them thoroughly when the surface of the soil was slightly dry. If a small number of leaves are dry and the soil in the pot is wet, it may be due to excessive watering or poor breathability of the soil and flower pot, resulting in rotten roots. It is necessary to remove the pot to clean up the black and rotten root system, and only keep the healthy root system before planting it in the pot again; if a large number of leaves are dry and the root system is seriously rotten, it is difficult to save it. The imbalance of soil ph could also cause the leaves to dry up. Azalea was suitable for growth in slightly acidic soil. If the soil was slightly acidic, it could be adjusted by adding appropriate amount of iron sulphuric acid or edible rice vinegar during regular watering. Unreasonable air humidity would also affect it. The growth environment of the cuckoo needed to maintain a high air humidity, and the minimum air humidity for home cultivation should be more than 60%. You can often spray water mist around the leaves with a small watering can, or use the method of spraying water 1 - 2 times a day under the premise of ventilation or using a tray to add water to evaporate and moisten. However, you must pay attention to good ventilation. Otherwise, spraying water in an unvented environment will make it difficult for the leaves to dry, causing the leaves to rot, blacken, and dry up. If the fertilizer was sprayed frequently, the leaves might be burned. Normal fertilizer should be poured into the soil and absorbed by the roots. Moreover, azalea had a low demand for fertilizer, so the fertilizer should be light to avoid excessive or too thick. If the application of phosphorous and potash fertilizer was insufficient during the flowering period, it would be easy for a large number of leaves to wither after the nutrients were exhausted after flowering. During the flowering period, the application of phosphorous and potash fertilizers such as Huaduo No. 2 and monocrescent phosphorus should be increased in time. In addition, dry leaves and branches with bad growth positions could be trimmed to keep healthy leaves. The healthy leaves should be sprayed with antimycrotics such as carbendazim, cyanothalonil or mancozeb to reduce nutrient loss and the probability of disease breeding. Also, check if there are any pests, such as indigo, etc. If so, spray carbendazim, thiophanate, and other strong internal fertilizers in time.

Du Juan flowers and fallen leaves?
Azalea leaves fall. The main reasons for its falling leaves were as follows: - ** environmental factors **: - ** Regarding water content, if the soil is dry for a long time, the plants will lose their leaves due to lack of water. If the roots are overwatered, the leaves will fall off due to the inability to breathe. - ** Fertility problem **: Too much or lack of essential nutrients may cause the leaves to wither and fall. - ** Illumination factor **: Azalea prefers a semi-shady environment. Too strong or long-term shade will affect its growth balance, resulting in falling leaves. - ** Biological factors **: - ** Dormancy period **: Some species of cuckoos naturally enter a dormant state during a specific season. At this time, they will lose some leaves. - Insect pests and diseases: Infestation by red spiders, aphids, and fungi will cause damage to the branches and leaves and even cause them to fall off.

Can Du Juan spray the leaves?
Azalea can be sprayed on the leaves. Azalea was a plant that liked moisture. Its leaves were sunken and had hair on them that could absorb moisture from the air. When the air was dry, the leaves sprayed water to increase the humidity of the air and prevent the leaves from drying up. However, there were a few situations that required attention: 1. Flowering period: When spraying water, avoid spraying it on the flowers to prevent them from withering in advance. 2. Under direct sunlight or high temperature: After spraying water, be careful not to let the water droplets stay on the leaves, otherwise the leaves may be sunburned. 3. During the rainy season or when the humidity is high, it is necessary to avoid excessive water accumulation on the leaves to prevent the leaves from turning black or rotting. Generally speaking, in spring and autumn, when the air was dry, water could be sprayed on the leaves once a day; in summer, when the temperature was high, water could be sprayed once every other day; in winter, when the temperature was low, water could be sprayed once every two days; during flowering or rainy season, water spraying on the leaves should be avoided as much as possible.

What if Du Juan's leaves wither?
The wilting of azalea leaves was mostly caused by improper maintenance, which could be solved from the following aspects: 1. ** Slowing down the seedlings **: The newly bought azalea leaves may wither due to changes in the environment. Place it in a warm (18 - 22 ° C), well-vented environment with scattered light, increase the humidity of the air (spray more leaf water), and keep the soil moist but not wet. Do not change the soil or apply fertilizer first. 2. ** Illumination adjustment **: Azalea flowers like soft light. If the leaves wither due to direct light, the potted plant needs to be moved to a cool, well-vented place with scattered light for maintenance. 3. ** Control of temperature and humidity **: Azalea prefers a warm and humid environment (temperature around 20 ° C). When the air is dry, spray more moisture on the leaves and the surrounding environment. 4. ** Pot soil management **: The soil that has been planted for a long time is hardened, and the poor ventilation and water penetration will cause the leaves to wither. Every 2 - 3 years, the soil should be changed to a new soil that is loose and rich in humus. The acid and base value should be adjusted with Ferrous Sulphate every month. 5. ** Water Management ** - ** Water shortage and drought **: If you forget to water and cause a drought, you must water it thoroughly in time (dry and wet). - ** Water Rotten Roots **: When watering too frequently causes the roots to rot and the leaves to wither, loosen the soil and place it in a well-vented place to promote the evaporating of water. After that, water it to ensure that the soil is moist but not wet. 6. ** Fertility Management **: If you don't apply fertilizer for a long time, the leaves will wither due to insufficient nutrients. During the growth period, the fertilizer should be applied once a month. Before the flowering period, the fertilizer should be applied to promote flower bud formation. The fertilizer should be applied frequently (after being sufficiently diluted). The fertilizer should be stopped when the temperature is high in summer and low in winter. 7. Pest control: When attacked by pests and diseases, the leaves will also wither. When infected by germs or pests, you should choose a targeted agent to spray on the affected area after being diluted with water. Once a week, three consecutive times will be effective. Daily ventilation and trimming should be done frequently. The novel "Acanthus Flower Blossoms" is equally wonderful. Everyone is welcome to click and read it!
What if the gardenia leaves turn yellow?
There are many reasons for the yellowing of gardenia leaves, and corresponding measures can be taken according to different situations: 1. Iron deficiency: If the tender leaves turn yellow and white, and the old leaves are normal, it may be iron deficiency. During the growth of gardenia flowers, in addition to nitrogen, phosphorus and potassium, iron was also needed. When the soil is alkali-based, iron cannot be absorbed. If the situation is not serious, you can use a 1:1000 concentration solution of Ferrous Sulphate to irrigate the soil in the pot. If the whole plant is seriously yellowing, it is recommended to change the pot. 2. ** Poor soil quality **: Poor soil quality affects the growth of roots, resulting in poor growth and yellow leaves. The soil quality should be improved to provide a good environment for the growth of roots. 3. ** Illumination problem ** - ** Too strong light **: gardenia flowers do not like strong light. Strong light will burn the leaves, causing the tips and edges of the leaves to be scorched and have yellow sunburn spots. In addition to winter, gardenia flowers should be kept in scattered areas in spring, autumn and summer. - ** Insufficient light **: Although gardenia flowers do not like direct sunlight, they also need sunlight. If the cultivation environment is dark, the leaves will turn yellow and fall off due to insufficient light for a long time. At this time, the gardenia should be moved to a place with good light. When the light is strong, it should be properly shaded. 4. ** Rotten Roots ** - ** Overwatering **: Overwatering will cause the soil to be too wet, the roots will rot, and the water will not be able to supply the plant normally. The leaves will turn yellow, usually starting from the old leaves. The new leaves will gradually turn yellow, but the veins will still be green. The pot should be removed in time, the yellow leaves and rotten roots should be cut off, and the roots should be sprayed with carbendazim. They should be placed in a cool and well-vented place to dry before replanting. - Water shortage: The soil is too dry, and the lack of water supply will also cause yellowing. Generally, the old leaves will start to yellow until they fall, and the new leaves will gradually wither. Watering should be done when the soil is dry and wet. The soil should be watered when it is dry or dry to the touch, but it should not accumulate water. 5. ** Fat damage **: improper fertilizer will burn the roots and affect the growth of the plant. If the new leaves were brown, the veins quickly turned yellow, and the leaves were uneven and yellowed, it might be a fertilizer disaster. He had to remove the pot in time, cut off the yellow leaves, clean the roots, pour water on the fertilizer to dilute it, and then put it in a scattered place to dry before putting it into the pot again. 6. ** Normal Degeneration of Old Leaves **: If the veins begin to turn yellow and gradually spread to the entire leaf and fall off, it may be normal for the old leaves to degenerate. As long as there are not many degenerated leaves per month, it is a normal phenomenon. 7. ** lack of fertilizer **: gardenia flowers need more fertilizer to grow and bloom. If they are not fertilized for a long time, the new leaves will turn light green. The old leaves will start to spread from the veins, and the entire leaf will turn yellow and fall off. Multi-element fertilizers should be supplemented during the growing season, and fertilizers with high phosphorus content should be supplemented before flowering. 8. ** Alkaline water quality and soil quality **: Long-term watering of gardenia flowers with tap water will cause the soil to be alkalized, causing the new leaves to turn yellow. Ferrous sulfuric acid can be added during watering to adjust the soil's ph and promote the formation of photosynthesis. The novel " Smelling the Jasmine Fragrance Again " is equally exciting.

Why are the dried leaves and tips of the Du Juan flowers?
The dried tips and leaves of the azalea could be caused by the following reasons: 1. ** Watering problem **: Too little or too much watering can cause this. When the summer temperature was high, the weather was sunny, and the air humidity was low, the potted soil could not be short of water for a long time. The lack of water would make the leaves dry and wilted, and even the yellow leaves would fall. However, if the watering was too much, the potted soil would be wet for a long time or the rain would accumulate water, causing the roots to be stuffy, which would also cause the leaves to dry up. In addition, if there was heating indoors in winter, the air would be too dry, and the azalea was a southern flower that liked humid environments. It was also easy to cause the leaves to become dehydrated, and the leaves would dry up or fall off. 2. ** Light factor **: If the azalea is exposed to the sun during the high temperature in summer, the leaves are prone to problems. It is best to give it shade, place it in a place without direct light, or place it under the tree to shade, so that the leaves will be in good condition. If the light is too strong, it will also cause the leaves to dry up. 3. "** Inappropriate fertilizer **: Too much fertilizer may cause the leaves to turn black, yellow leaves to fall off, and other dry leaves. Especially when the summer temperature reaches 30 degrees, it is easy to cause fertilizer damage and cause the leaves to turn yellow. 4. Soil problem: If the soil in the pot is not changed for a long time, the soil will become barren and hardened, which is not conducive to the growth of azalea, resulting in dry leaves. 5. ** Air humidity **: When the air humidity is too low and too dry, especially when there is heating indoors in the winter in the north, the azalea leaves are easy to be dehydrated, which will lead to dry and yellow leaves or fall off.

What is the reason for the yellowing of Du Juan's leaves?
The yellowing of azalea leaves can be caused by the following reasons: 1. [Conservation problem: Azalea needs suitable growth conditions.] If they don't get enough water or sunlight, the leaves may turn yellow. For example, exposure to strong sunlight in the summer and exposure to ultraviolet radiation could easily cause yellow and scorched leaves. Long-term exposure to dry soil in the basin could also cause the leaves to turn yellow and scorched. Winter is not cold-resistant. If it is not moved indoors for maintenance in time after winter, and the stable temperature is above 10 ° C, yellow leaves and scorched leaves may also appear. 2. ** Soil problem **: Azalea flowers prefer acidic soil, and the pH value is usually between 4.5 and 6. If the soil was too salty, or if long-term cultivation caused the soil to become salty, hardened, malnourished, and lacked iron, the leaves would easily turn yellow. 3. ** lack of fertilizer **: Azalea flowers have a high demand for nutrients, and they consume a lot of nutrients when they grow and bloom. If the soil lacked essential nutrients such as nitrogen, phosphorus, and potassium, the leaves would easily turn yellow if they were not fertilized in time. The bottom leaves might gradually turn yellow and fall off. 4. ** Pests and diseases **: Some pests and diseases can cause the leaves to turn yellow, such as leaf mites, aphids, and insects. 5. ** Over-fertilisation **: Although azalea flowers need fertilizer, excessive fertilisation may cause damage to them and cause yellowing of the leaves.

When autumn is thick, the leaves turn yellow
The main reason why the leaves turned yellow when autumn was getting stronger was that the temperature dropped and the sunshine time shortened, causing the amount of photosynthesis in the leaves to decrease, thus revealing the colors of other vitamins, causing the leaves to turn yellow. Among the autumn scenery, there were many places to enjoy the beautiful autumn scenery where the leaves were turning yellow. For example, in the Changbai Mountain in the northeast, there were many layers of colorful forests in the autumn scenery. Benxi was the capital of maple leaves in China, and the maple leaves were gorgeous. On the red beach of Panjin, you could see the magical landscape of half sea and half flame, and the surrounding leaves would change color according to the season. The trees in the Longwan Group Geoparks would also change color in autumn. The red maple, green pine, and white birch in the Xiaoxing 'an Mountains outlined a colorful world, and the leaves would also turn yellow. The red leaves all over the mountains and plains of Laobian Valley were also a manifestation of autumn. In Beijing, the gingko trees in the Forbidden City turned yellow and the red palace walls gave off a strong atmosphere. The gingko avenue in front of the Altar of Land and Grain in Zhongshan Park was golden in late autumn, and the metasequoia forest would also turn red. The redwoods and ash trees in the Summer Palace were very beautiful in autumn. The Great Wall forest in autumn was dyed. The red maples, yellow houses, and gingko trees in Xiangshan Park were everywhere, and the leaves gradually turned yellow and red. Single-string paizi songs, such as Chaqu, Fu, and other topics, also mostly described the scenery of the middle of autumn, such as gradually turning yellow.

What is the reason why the leaves of Du Juan flowers are dry and do not fall?
Azalea leaves withering could be caused by the following reasons: 1. ** Watering problem ** - ** Overwatering **: If the soil in the pot is too wet for a long time, it will cause oxygen deficiency in the soil, causing some roots to rot, hindering normal breathing and absorption of water and nutrients. Although the leaves had dried up, the dried leaves did not fall for the time being, probably because the connecting part of the petiole and the branch had not completely died. - ** Too little watering **: If the flowers are not watered or watered halfway for a long time (that is, the upper part is wet and the lower part is dry), it will affect the absorption of nutrients. It is also easy to cause the color of the leaves to be dull and the leaves will gradually dry up. However, due to the physiological structure of the plant, the leaves may still be attached to the branches. 2. ** Fertility factor ** - ** Over-fertilisation **: Over-fertilisation will cause the new leaves to be plump and uneven, while the old leaves will be dry and yellow. The excessive fertilizer might have damaged the roots and caused the leaves to dry up, but because the drying process was relatively slow, the leaves had not fallen off yet. - ** Long-term fertilizer loss **: Long-term lack of nitrogen fertilizer or soil change, resulting in a lack of nutrients such as nitrogen in the soil, resulting in thin and yellow leaves and withered leaves. The lack of nutrients may affect the formation of the separation layer, causing the leaves to not fall off. 3. ** Illumination ** - ** Too strong light **: Azalea flowers like semi-shaded environments. If exposed to strong sunlight for a long time, the leaves will be burned, dehydrated, and dry up. However, due to the plant's own regulation mechanism, the leaves might still remain on the branches. - ** Insufficient light **: Long-term insufficient light will affect photosynthesis, causing the leaves to be unable to synthesize enough organic matter, causing the leaves to gradually wither but not fall. 4. ** Uncomfortable temperature ** - ** Too high temperature **: The most suitable temperature for the growth and development of the cuckoo is 15 - 25 ° C. If the temperature is above 30 ° C for a long time, the leaves of the plant will dry up due to the rapid evaporating of water. The dried leaves may not fall off. - [Low temperature: Azalea is not cold-resistant. When the plant is frozen by low temperature, the leaves will dry up. The leaves may not fall off because they are not completely dead.] 5. ** Soil conditions ** - [Soil Discomfort: Azalea prefers loose and airy acidic soil. If the soil is too viscous or is too basic, it will cause problems in the growth of the plant and the leaves will wither.] In the case of poor soil conditions, the dried leaves might not fall because the connection with the branches was not completely broken. 6. ** Unreasonable air humidity **: Azalea flowers like high air humidity. When the room is dry, if it is in a dry environment for a long time, the edges of the leaves will turn black and dry. The dried leaves may not fall for the time being.
