1. Replenish water: water the jasmine once permeable, and loosen the soil during the watering process. 2. Clean up fertilizer:

Flush out the excess fertilizer with clean water and move it to a ventilated place. 3. Increase the temperature: Move the jasmine indoors for maintenance, and control the temperature above 5 degrees Celsius.

4. Transplanting: Replant with soil with strong air permeability and good drainage.

What to do if the jasmine leaves turn yellow and dry up and lose the leaves.

Jasmine leaves are yellow, withered, and how to deal with falling off.

1. Replenish water.

The yellowing and withering of jasmine leaves may be the cause of lack of water, at this time, it is necessary to water it once, and loosen the soil to allow water to penetrate, and move the jasmine to a place with less light, slow down the rate of water evaporation, so that it can resume growth.

2. Clean up fertilizer:

After the jasmine leaves wither and fall off, check the root system in time, clean up the excess fertilizer, if you apply liquid fertilizer, you can water the jasmine more, dilute the fertilizer in the soil, and then move the jasmine to a ventilated place for maintenance.

3. Increase the temperature.

Jasmine has poor cold tolerance, and if it grows at a low temperature for a long time, the leaves will suffer severe frostbite, resulting in the situation of yellow leaves drying up and losing leaves, so it is necessary to move the jasmine to a warm place and control the temperature at about 15 degrees Celsius.

4. Carry out transplanting.

Jasmine flowers prefer to grow in a substrate with strong air permeability and deep soil, and if the soil is not suitable, it will lose its leaves, so it needs to be dug out of the soil and replanted into nutrient-rich, permeable soil.

African jasmine is native to southern China and Southeast Asia. Prefer a warm, sunny, humid and airy environment. It is a very popular indoor foliage plant.

Causes of leaf yellowing Usually the leaves of African jasmine in the nuclear world suddenly turn yellow, which can be roughly divided into three situations. One is the lack of potassium in the plant, at this time, the leaves of African jasmine will turn yellow, and the second is that the position of the pot is not reasonable, resulting in the lack of sunlight on the plant itself, which will make the leaves lose green and yellow. The last case is that the temperature is not suitable or the ventilation is not enough to accumulate water, which can also cause the above situation to occur in African jasmine.

Coping method In response to the cause of the occurrence, we will sit down and look for a solution.

If the leaves are yellowed due to potassium deficiency, you can choose to add compound fertilizer or potassium nitrate. About once every ten days, top dressing twice, the situation of yellow leaves will improve.

African jasmine, like the sun, if the position of the pot is too dark, resulting in the plant itself can not enjoy sufficient light will also make the leaves yellow, in the face of this situation, we should timely carry and adjust the placement of the pot, so that the plant fully receives the light.

If you find that the leaves of African jasmine are yellow, it is likely to be caused by excessive water accumulation, and the treatment method is to pay attention to the intensity of watering, control the amount of water, open windows frequently for ventilation, and carry out soil replacement work if necessary. In addition, it is also necessary to pay attention to maintaining the indoor temperature, keeping the temperature above 10 degrees Celsius during the wintering period, and changing the hidden limbs to prevent the leaves from yellowing, you can add a small amount of ferrous sulfate during the growing season and fertilization, which is also a good method.

Shedding and drying of African jasmine shoots can be caused by a variety of reasons, such as lack of light, root injury, low temperature, or disease. Here's how to deal with it:

Lack of light: The growth of African jasmine needs sufficient light from the cemetery, do not put it in a corner or too shady place to maintain, to avoid poor light or long-term in a dark place, it is easy for African jasmine branches to rot.

Root injury: In the process of repotting, repotting, potting, transplanting or transporting African jasmine, you must be very careful not to let African jasmine hurt the roots or branches, and keep the root soil ball intact. Once the roots of African jasmine are accidentally rotted, then the branches, leaves, and flowers will be affected, and the branches and leaves will stop before they bloom.

The temperature is too low: The indoor temperature needs to be kept above 10 in the winter chain season to meet the growth needs of African jasmine. When maintaining indoors in winter, do not place African jasmine potted plants in cold air vents or near windows.

At the same time, it is necessary to reduce watering in winter, and generally do not water African jasmine if it is not too dry. In winter, just keep the soil moisture at 20-40% fine.

Disease causes: If you find that the branch is diseased, you need to cut off the diseased branch immediately to avoid affecting other branches. In addition, we must pay attention to environmental ventilation and reduce humidity in maintenance, which can increase the disease resistance of plants and avoid aggravation of harm.

Reason: African jasmine is a very light-loving flower, and it is best to give it full sun when raising it. If it is left in a dark-deficient environment for a long time, it will cause problems with its growth, and some leaves will be soft and drooping.

Treatment: Transfer it to a very sunny place for maintenance. Especially when the light is relatively weak, try to keep it in places such as dusty reeds and balconies, and not let it lack light.

Reason: If this problem occurs in winter, it may be because the temperature of the environment in which it grows is too low, causing it to freeze.

Solution: Move it to a heated room and raise the temperature appropriately to ensure warmth. Be careful not to place it next to a window where cold air blows.

Reason: If you usually water it too much, causing its root system to rot, then it will also cause it to have soft leaves.

Solution: Use a shovel to loosen the flower soil slightly, then take out the plant and shake off the flower soil adhered to it. After that, use a knife to slowly remove the rotten area and disinfect it, and then plant it in new flower soil and slowly maintain it.

Problem description: The African jasmine I raise has lost its leaves. I don't know what to do.

Analysis: There are several situations for your reference: Nitrogen deficiency: The plant is thin, the branches are slender and hard, and the leaves are small and the flowers are small. The leaf color gradually fades from the old leaves to the new leaves, and then appears reddish-purple, until it turns yellow and falls off, and in severe cases, the whole plant loses its green color.

Prevention and control methods: Increase the application of well-rotted human feces, cake fertilizer, manure or ammonium sulfate, urea, ammonium nitrate and other fertilizers.

Phosphorus deficiency: The leaves turn dark green to copper, and the veins (especially petioles) are yellow with purple in color. Flower buds are difficult to form, and the flowers are small and few and the color is pale or thick, resulting in poor fruit development and even early wilting.

Prevention and control methods: increase the application of bone meal, fish meal, poultry fertilizer or superphosphate, ammonium phosphate, potassium phosphate (phosphorus, potassium compound fertilizer), generally with about 0 10 aqueous solution as root top dressing.

Potassium deficiency: The plant is short and the stem is soft and lodging. The leaves are often shrivelled, and the old leaves appear black-brown spots along the leaf edges from the tip of the leaf, and the surrounding leaves turn yellow, while the middle and leaf pulse are still green.

Control methods: increase the application of plant ash, 1 2 potassium chloride aqueous solution (bulb and root flowers should not be used), 0 30 0 permeable potato 50 potassium nitrate aqueous solution as root top dressing, potassium phosphate and other inorganic fertilizers can also be used.

Calcium deficiency: young leaves are green and shrivelled, leaf margins are curled with white streaks, flowers are blocked, and new leaves are difficult or diseasefully twisted.

Prevention and control methods: Half a month before sowing or potting, apply an appropriate amount of calcium chloride in the soil, which can play a role in increasing calcium and disinfection (acid-loving flowers should not be used), and calcium nitrate can also be used as top dressing.

Magnesium deficiency: The plant does not grow vigorously. The old leaves gradually lose green and turn white from bottom to top from the leaf margin to **, and various spots appear on the leaf veins, and finally the whole leaf turns yellow.

Prevention and control methods: spray 3-4 times continuously with 0 20 0 40 magnesium sulfate aqueous solution, with an interval of 7 10 days each time. In the soil with severe magnesium deficiency in Tuanshan, 5 10 kg of magnesium sulfate per mu is used and mixed with basal fertilizer in autumn or winter and applied to the soil.

Sulfur deficiency: The young leaves begin to yellowish from the veins and finally until the whole leaf turns yellow, and the root system is not developed properly.

Iron deficiency: yellowing from young to old leaves.

Sulfur deficiency and iron deficiency prevention and control methods can be sprayed with 0 30 ferrous sulfate aqueous solution, 3 times in a row, with an interval of 1 week each time, and the fog point should be fine and uniform when spraying. At the same time, 0 20 urea iron solution can be used for extra-root top dressing.
