The jasmine leaves crumpled and curled down

Jasmine leaves curls down, may be caused by the soil in a moist state for a long time, the later maintenance of jasmine needs to be reasonable watering, found that the soil is dry, timely watering and moisturizing. It may also be caused by an aphid attack, which can be sprayed with dimethoate solution on the leaves**. It may also be caused by unstable temperature, and the ambient temperature needs to be stabilized between 15 and 25 when maintaining jasmine in the later stage.

Jasmine flowers are suitable for growing in a moist environment, but if the soil is moist for a long time, it will cause jasmine to grow poorly and the leaves will curl. Therefore, when watering jasmine in the later stage, it is necessary to take the method of "not drying and not watering, watering and watering thoroughly" to replenish water, and find that the soil is dry and white, and it is necessary to water and moisturize in time.

After jasmine leaves are attacked by aphids, it will also cause jasmine leaves to curl and the leaf surface will be uneven, so it is necessary to prune off the curly leaves and spray dimethoate solution on the leaves**. When cultivating jasmine in the later stage, it is necessary to ensure that the environment is ventilated and breathable to reduce the breeding of pests and diseases.

Jasmine flowers are suitable for growing in a warm environment, and if the temperature difference changes too much when cultivating jasmine, high temperature or extreme cold weather will cause the leaves to turn yellow. Therefore, when cultivating jasmine in the later stage, it is necessary to stabilize the ambient temperature between 15 and 25.

Jasmine is a sun-loving plant, and its branches and leaves can only grow vigorously in a sunny environment, but if there is a lack of attention for a long time, it will cause the jasmine leaves to turn yellow and appear curly. Therefore, it is necessary to place jasmine flowers in a bright place for maintenance every day, and only need to do shade measures when the light is too strong.

Jasmine leaves turn up, and the roots are difficult to absorb water for drought; The jasmine leaves bend downward, and the big roots of the pot are suffocated by the wet water; The temperature fluctuates, and the new leaves are cold and deformed; Improper fertilization in spring, wrinkled and hypertrophied old leaves, ugly and ugly new leaves, and deformed; Jasmine insect pests suck leaf sap, and the leaves are turned back and rolled inward to form difficult to form; Jasmine suffers from infected nodules, and the new leaves are naturally deformed; Jasmine injuries accumulate, and new leaves are twisted and difficult to flatten.

Raise flowers and roots. The roots are good and the leaves are spread and flattened. In the maintenance of jasmine, it is common to have symptoms such as uneven distortion after the sprouts are formed and the leaves are spread, and the tips of the sprouts are black and falling. The main reasons are still there: light, soil, fertilizer, temperature, and the focus is on ventilation.

Pest controlJasmine is susceptible to insect pests such as red spiders, so ventilation should be strengthened, attention should be paid to observation, and once insect hazards are found, dicofenol should be used for prevention and control in time. Jasmine leaf spot is a common disease of jasmine, which generally begins to occur from May to June, and the peak of the disease is from July to August. At the beginning of the disease, light brown spots are produced on the infected leaves, which then expand to the periphery, and the diseased part becomes thin and brownish transparent, round or irregularly shaped, and the diseased part becomes thin, translucent, brown, and the edge of the lesion is obvious.

Finally, the lesions are covered with black granules. Diseased leaves should be removed in time and destroyed in a centralized manner. During the onset period, spray 65% zeb wettable powder 600 times to 800 times, or 75% chlorothalonil wettable powder 800 times, spray 3 to 4 times, with an interval of 10 to 14 days, the curl of African jasmine leaves may be the cause of sun exposure or too dryness.

African jasmine does not like direct sunlight, prefers semi-shade, and requires good ventilation. Likes moisture. In summer, it should be cultivated in the shade, and the amount of water should be strictly controlled in winter, and it is better to be dry.

1. Excessive sunlight: In summer, jasmine is exposed to the scorching sun for a long time, which will burn and cause the leaves to curl.

2. Diseases and pests: Jasmine is not properly maintained, if it is infected with pests and diseases, it will cause the leaves to curl and dry up.

3. Root rot: Excessive watering and fertilization during breeding will lead to root rot and cause leaf curl.

4. Soil problems: If the soil is compacted and not breathable, it will limit the growth of roots and cause the leaves to curl.

1. Strong light: Strong light in summer will accelerate the evaporation of jasmine water, resulting in curling of leaves. 2. Soil alkaline

Alkaline or compacted soil can cause jasmine roots to breathe poorly. 3. Root ulceration: excessive watering or excessive fertilization can easily lead to root rot and cause leaf curling.

4. Pests and diseases: Jasmine encounters pests and diseases during growth, which will cause leaf curl.

1. The light is strong

Jasmine likes light, but can not be exposed to strong light for a long time, otherwise it will lose a lot of water, resulting in curling leaves, so in summer jasmine should be cultivated in astigmatism or soft light, and you can also build a shade net.

2. Soil alkaline

Jasmine is suitable for planting in loose and breathable slightly acidic soil, soil alkaline or soil compaction will cause jasmine roots to breathe poorly, nutrients can not be transported normally, so that the leaves curl, so in the process of cultivating jasmine, the soil can be loosened regularly, and the appropriate amount of ferrous sulfate is applied to the soil to maintain acidity.

3. Root ulceration

In the process of maintaining jasmine, if there is too much watering, excessive fertilization, etc., it will lead to root rot, and long-term inability to absorb water and fertilizer will cause the leaves to curl, the jasmine is separated from the pot, pruned the rotten roots, sterilized and disinfected and replanted.

4. Pests and diseases

Jasmine is susceptible to pests and diseases during the growth period, which will seriously threaten the growth of the plant, resulting in the leaves being eaten, curled and dried up.

Jasmine is relatively fond of sunlight, and if it is not allowed to see the sun for a long time during the maintenance process, the plant will grow very poorly, and the leaves will not only wrinkle but also turn yellow. The plant should be given as much light as possible, and its leaves will grow normally under photosynthesis, which will not only improve the wrinkling phenomenon, but also make the leaves grow stronger and greener.

It is suitable for growing in a humid environment, but it is more afraid of stagnant water, if it is overwatered, the plant is easy to rot roots if it is in a state of stagnant water for a long time. After the root rots, its leaves will have many undesirable manifestations, such as wrinkling, yellowing, or losing leaves. It should be well drained and controlled, and watered in small amounts.

During the maintenance of jasmine, you can't apply too much fertilizer, otherwise the root system will not be able to absorb it, and if the amount of fertilizer is too large, the leaves will be wrinkled, and in severe cases, the buds on the plant will be burned to death. The amount of fertilizer applied needs to be strictly controlled, and it should be applied in small quantities and many times. However, it should not be left unfertilized for a long time, and the plant will not grow well when there is no fertilizer.

Leaf curling of Amaranth flowers should be a symptom of the leaves being unable to get water from the root system, resulting in dehydration and leaf curling, or caused by pests and diseases.

1) The phenomenon of yellowing and curling of leaves caused by excessive watering, usually watering is not easy to be too wet, and the overly wet soil is easy to accumulate water and produce root rot and yellow leaf curls. It is best to keep the soil dry and watered, so that it is not dry and watered, so that it is conducive to the growth of the root system, so that the phenomenon of yellow leaf curling is not easy to appear.

2) The soil board is hard and impermeable, resulting in the inability of watered water to penetrate into the soil layer, resulting in the inability of most of the roots to absorb water and nutrients, resulting in leaf water loss and dystrophy and leaf curling. The best way is to use a loosening tool to insert the potting soil into the potting soil, gently shake the potting soil to make the potting soil have a cracked feeling, and the proper loosening soil is conducive to soil loosening, ventilation and drainage, and is conducive to root growth.

3) There are pests and diseases that are also easy to cause leaf curling, it can be observed that if the leaves are caused by insect pests, insecticides can be used to kill insects, and if they are caused by fine in, antibiotics can be used to treat diseases.
